What's new

2005 Escalade EXT (aka GMT 800 argument thread)

And thats where the awd load comes in.

Gm spec is all must be within 1/2" circumference.

Same goes for posi diffs.

you also understand that 246's never really release the front dshaft, they just back the psi off the clutch pack.
Burning up constantly engaged (whether partly or fully) clutches from mismatch be it left right and/or front to rear makes sense.

Burning up spider gears from hundreds to maybe a couple thousand RPM under mostly no load than they were already under doesn't.

Heck, I ran one of my Subarus for a couple years with 4.10 up front and 3.90 out back (not to be confused with outback :laughing:) until I happened across a matching 4.10 with some other parts. It never engages the rear on the dry unless you mat it so it was fine. Fucker did great donuts. :laughing:
 
Funny guys are complaining about awd eating front diffs, everything is spinning all the time in 4wd also. The front just doesnt nessacarily spin full speed. All the shafts and spiders are rolling at wheel speed and the innermost shorty is actualy spinng backward against the output shaft on the pside. So basicaly 2x as fast.
What about when the hubs arent locked? Sure there is a litle friction to spin them, but not much.

I cant think of any one of the 100+ ive done that was specificaly a awd.

Ive bought awd front and put the 4wd tube on them because it was the only one i could get atm and was the right ratio.

i did deal with one a cust brought in because he couldnt get the d-side shaft out. I burned up so hard it seized the shaft in the spider.


Its not that 400/800 are better/worse, its 1500 problems.
Ive never done a 2500/3500 front 9.25.
Ive only rebuilt 3-5 14bs (9.5 and 10.5)
I just picked up an 03 Tahoe with 200k. It was a grandpa truck and the passenger and back seat were barely sat in. Guy used it for bird watching and died 10 years ago, sat inside a garage for the last 10 years, wife drove it every once in a while until she died. aaaanyway..

It has the front end whine that I can feel/hear with the radio off when it gets over 65-70. Doesn't sound like unit bearings because it doesn't change when I swerve or turn the wheel. What do you see go bad in these things when they whine? Carrier bearings? The shaft needle bearings? Shouldn't be the pinion. Also, mine has 4.10s.

I get a weird converter unlocking/ locking thing at about 50 with a little load on the trans too. Doesn't do it in tow haul.

Should we start a GMT 800 thread?

I have an 02 2500hd that's been great. blackbear tuned it at 23k and I want them to do this one so the trans shifts like it's supposed to. Torque management sucks.
 
If anything's whacky electronically in the escalade, kust pull the negative battery terminal and let it sit in time out and think about what it's done for about 5 minutes. Reconnect, turn key on and let it recalibrate everything for a couple minutes, you'll hear all the HVAC doors cycling and when it stops, start it and go for a relearn drive.

A front end whine at 65+ you have to turn the radio off to notice on a 200k truck; these guys in this thread are right; these things are pure junk.:laughing: double check the fluid level in the front dif, because they occasionally are dry as the sahara :eek:.

i cant think of another IFS 4wd platform that regularly sees 200k outside of toyota and all i have is a 140k lexus to observe there, but I assume the dif being mounted to the frame transfers that noise to the cabin more directly. {a 200k XJ has the solid axle and suspension isolating it and the rattles and squeaks over 60 you'll never hear the whine if its there and are likely too occupied gripping the wheel in case death wobble to notice;:lmao:} I'm not saying its a beefy dif in the half tons, but i noise you cant hear over conversational volume levels isn't out of my realm of acceptability.

thats sort of typical 200k 4l60 stuff; {exacerbated by 4.10's- a short wb (not burb/xl) with the deep gears is pretty unicorn since like 80% or so are 3.73 } that tc lock hunting creates wear, so i'll adjust speed or toggle the tow/haul button on/off as needed to help where i can to maximize the trans lifespan.

i think this is an official hijack acknowledgement and thread title change away from becoming that. :confused::homer: {edit: looks like someone did actually chang the title; sorry for the hijack Pyleit :beer:!}

6.0 or 8.1?- i love my 8.1 2500hd but definitely couldn't tell you if there was a gear whine over 50 mph cause you can't hear shit over the allison whining. :smokin: I called blackbear a few weeks ago and they want $700 to tune it ( including buying the data logger hardware dongle thing.)

At this point in your tahoe's 4l60 lifespan, i wouldn't touch the tuning until there's a rebuild being installed if it were my $. ( and maybe run in tow haul in anything but flatlands.)

very off topic in this thread, but are these people who want to fly for the airlines starting at 40-50 years old? Seems late to jump into that career.

My favorite engineer here is late 30's and is just now starting pilot training from 0. He wants to fly commercial freight. Hopes to be employed flying in 5 yes I think he said.

And Honda. And Subaru. And probably most boring blob shaped crossovers save the few with glaring engineering failures built in.

Times change. 200k means nothing these days old man.

well, ackchyually... your examples are awd and not 4wd 🤓 :clown:, :flipoff2: {unless your going deep into throwback land to subaru loyale/DL/GL and Honda wago-van with the shifter mounted push button...}

I've also owned several MDX's get center diff/tcases replaced to address whining conditions within 200k. {much-less their transmissions made of eggshells which can make a 4l60 seem robust} :stirthepot:

Yes, in the last 13 months I have had a lawyer, landscaper, retired military, car salesmen, realtor, and college professor all come through the new hire program.
Flying sounds FUN! Where do I send my resume?
 
I never will get the fanboi love these things get. Bro these are great trucks just be sure to rat hole 5k for when the:
4l60 goes duuuuuur
Front diff goes
T-case goes
Air ride goes
Stepper motors go
4l60 shits again.
But really bro these are great fucking rigs. Talk about sympathizing with your captor. Yeah that’s what I wanna do. Set aside a spare 5k for my 3k truck. I understand putting some money into a platform you like but fuck me the shit that gets rattled off that goes wrong with these makes them a non starter. Fuck the general.
get a 2wd 2500 and all the problems disapear.

I had a couple TL's, the first one was a 2000 and had a trans around 100 and went to 260k until I hit a curb and bent the frame into the crank pulley. Car was flawless. Second one was an 08 that was flawless except it was a crash magnet. Tagged it, and literally an hour later, got rear ended, fixed, then hit two months later in a perking lot from rear door to decklid, fixed then t-boned a guy who turned in front of me 6 months later. Trans was screwing up so I let them total it out.

Well hell, at this point what's one more derailment tangent in this thread;

40-something midlife crisis non-awd honda product storytime:

the 2nd generation legend (91-95) was probably peak Acura {along the same timeframe as the NSX development}

Rumor has it that it was Acura's S-class killer attempt; they developed it so extensively that they ended up losi money on every one even selling them at like $50k a piece in the early 90's; real wood accents; built super well- as close as the japanese came to bank-vault doors while still being mindful of weight in their jap-ness; it was geared aggressively and so pretty quick and loved the cruise set at triple digits. the 6 speed GS trim manuals are the grail cars.
{Although now i recall that it had a front half of a t-case re-routing a rwd configuration v6 & trans with a drive shaft back up to a front dif that was known for needing maintenance. but it was easy to overlook for the' jap s-class'. }
a clean example would absolutely be on my lottery winner collection list.

the 5 cylinder Vigor of similar vintage was another interesting odd-duck.

The 2nd gen integras were also in the discussion of peak acura.

The first gen tl autos were regularly failing within 60k-80k mi and acura good-willed a metric shitton of replacements to about anyone who produce a single transmission fluid service record. the interiors were a bipolar assortment of very nice and accord parts bin 'meh'.

The 2nd gen TL type S and CL type s were torque steering, tire spinning 320hp vtec handfuls. ( i think i burned 30% treadwear off in a TL type S auto loaner in the 48 hours they had my MDX in the service bay) the interior quality was squarly in the middle of the downhill slide to leather wrapped honda trim quality. And my CL type s 6 speed test drive was short but fun- i hit somewhere approaching 100 at the top of 3rd gear and then asked the salesman wtf I was supposed to do with the other 3 gears that didnt involve jailtime ( to the best of my recollection it was crossing 70 at the 2-3 shift that fawker had legs) and we made a u turn and terminated that drive.

the RL's were always meh to me, the future gen TL's are ugly accords;

Acura cars really should be an MBA school case-study in how fast and far you can torpedo a brand into irrelevant obscurity. Spin-off anyone???
( i've got no hate for the MDX/RDX but they don't have very much marketshare in their categories in recent history.)

The market says it means something. Is it just a legacy of "boomernomics" or are
It doesn't mean nothing but for a mechanically inclined potential buyer it shouldn't mean much if the big stuff checks out (oil pressure, blowby, trans operation).

you just pissed because nobody wants a used-up lesbaru?
You think I sell shit? :lmao:

They wont get that argument. Thats what i tried to point out was that they should be looking at what people wont sell or let the company take after its totaled. But somehow muh resale value more importanter.

I know i said i was out, but this is too rich;

So if my reading comprehension is accurate, your stated premise is that there's not just hundreds, but thousands of guys across this country that won't let their jellybean F-150's with 200k+ on the odometer go to auction, and are buying them back after getting totaled because they recognize quality and that's the reason why there are 2-3x more GMT800's with big odometer readings across literal thousands of datapoints at insurance auction lots with locations distributed across 48 states???

I'll give you one thing you move the goalposts of an argument well. When i countered your first point on great dds about gmt800s then we were suddenly only talking about full size trucks. Now suddenly you assume i mean jellybean f150s. Which again went against the original point but i digress.

I also pointed out that im far more interested in what is still running around and didn't fold up like a wet pool noodle from craptastic gm build qaulity in an accident. What i said was mile for mile a ford was a better vehicle than a gmt anything and i meant it. I have owned and driven alot of original drivetrain high mileage cars. I get a huge kick out of them for some reason. There have been fords and lesbarus and even vws in there. Never a gm product.

But more to the point what im saying is that a vehicle that has been good to me even totaled does in fact get bought back and kept for parts for whatever twin replaces it or to donate to other projects if i cant save it. So yes id say anything that someone let go to auction is a turd..... That said i do know way more people in my life that bought back and fixed fords than anything else in my life since you insist on pointing to auctions.

I know you arent going to have your mind changed because you've said as much. Good for you. Ill keep buying up wrecked fords to put back together and you keep watching gm piles rust in auction sites. Everyone is happy.
 
Enjoying the banter and no dogs in the fight. On the grounds laid out, I feel WTF has the edge.
GMT’s are pretty shitty but it’s so cheap to fix them! :flipoff2: :laughing:

jellybean (97-04) is just the bulk of years that overlap with the 99.5-06 GMT800 , certainly not being predatory

so fords handle a traffic collision impact so far superior to GM that there's less than half as many/ half the frequency of them that getting insurance totaled across thousands of repetition cycles?

that's the way you and i see it, but you'd have to admit that it's certainly not how the majority of the motoring population operates. Shit gets crumpled up; insurance pays out, they go shopping.

I'm just here for the BS and hypothetical discussion. Just about everything i drive is salvage totaled anuction bought and returned to the road; i suspect we might be more similar than you think. 👍 {You leave the GM's to me and you can have all the jellybean fords your heart ever desired:flipoff2:}
disclaimer: I will be snagging a 6.2/6r140 out of an auction somewhere at some point to put in grandpa's bump side F-350 in my barn.

Im not really after the jellybeans. Which is why again i didnt base my argument off overlapping years or full size truck because that wasn't the claim in the original post i replied too. The claim was the gmt 800 was the most reliable pound for pound daily short of a jap car or a diesel and obviously i disagree but i think we both know we arent going to convince the other so we can stop the derail here.:flipoff2: That said i mostly just enjoy pissing in gm fans cheerios for thinking made anything decent after 1972 (they haven't). They are 100% percent disposable tupperware with an ok transplant under the hood. Not a good transplant but ok given the price point.

Ohh and this is more my speed than a jelly bean:flipoff2:

A goodwrench reman 4l60e is 2700, probably 2400 at the counter if you're not a douche.

A local rebuild on the bench should be 1500-2k

Jegs has a reman for 1700. It's not a huge expense considering new half tons are 50k

Mine personally went 186k with no known maintenance, bought used at 164k and previous owner said he had no record of fluid changes. and my friends went 175k with zero maintenance and regular towing, original owner

It's no 4l80e, or 6r140, or zf6, but if it moves a 5500lb truck around for 15 years and costs 3k to get the rest of the pile to 320k, that's pretty reasonable cost of ownership.

*I liked them a lot more 3 years ago when they were $1600 at the dealer counter

My moms truck:flipoff2:. She cant and shouldnt be using it in her 70s. Although for the record i did say the gmt 400 was a way better truck than the 800. I meant that too. Less hp sure but way simpler to work on and better looking. :flipoff2:

well shit that ain't horrible. When I was looking around for my escalade local rebuilders wanted 3-4k, Monster shit rebuild was $2-3k, etc. Never came across GM, wonder who rebuilds for them, if its in house or not

problem in the Northeast is the rest of the shit you touch to get the trans out. Good luck getting the exhaust off. And plan on replacing all the trans lines and cooler, or just ditch it entirely. Everything is gonna be rusted and shitty to remove. Clean truck, sure. Rusty, fawk that job, I'll buy a "new" one for cheaper that's less rusted

Yeah, starting with the right truck makes a difference. I drove 3 of them the day I bought mine, I got the backstory, 2nd owner, knew the original owner, knew the trans was untouched, knew the fuel pump was original. The leather seats were FUCKED. I bought cloth seats from a crew cab and swapped them. A mech buddy had a shop and owed me some labor, so I dropped it off on empty with a new fuel pump, new rear coils, a stack of maintenance parts and let him at it. It was a solid dd/ family trip truck for 4 years before needing another round of PM, I elected to replace it
