What's new

2005 Escalade EXT (aka GMT 800 argument thread)

My brother just shelled out somewhere between $4-5k to rebuild and tune the 6l80 in his 99k mi 2017 Yukon XL that probably still has shiny paint in the receiver hitch,
This one bailed around 75k and was under warranty, they flushed it and threw a new TC in it. Working so far... but... you know.

trade that fucker in while you still can; i can hear that time bomb ticking from here.

I just had a 2021 z71 burb rental in montana that definitely impressed me a ton more than the 15-19's did. It would be really tempting to me if i was a truck payment kind of guy, and didn't have a collection of GMT 800's and parts curated over many many years of auction hunting and marketplace dealings.

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.

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.
 
sounds like the canadian winters fucked his truck up;

however eating brakes is not something i have ever heard as a common issue with the platform, perhaps rusty/ corroded calipers/slides?
Brakes was a combination of calipers failing (rear) eventually but the first two times was a material transfer issue destroyed my rotors. I was running Wagner brakes and flipped to Akebono after the second time. Installed rebuilt calipers up front at that point due to age and not a clamping issue.

Our winters are hard as fuck on things looking back at what I did to that truck.

I sold it before the locals had a third chance to steal it and likely torch on the Rez. Sold it in 2019 because it wasn’t safe to park anywhere

My buddies 07 classic was ripped off about two years ago now… stripped. We need to bring back public hanging
 
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.

All brands are all pieces of shit.
I’d rather repair what I had to do versus cam phasers/chains or turbos on a Ford

That’s like $700 in u-pull parts at regular pricing and there’s dozens of them to select from in every u pull in the country.:flipoff2:

Just fir the record, How many 4l60’s have you personally blown up to the point they wouldn’t operate as a dd?
 
I’ve had two go tits up on me personally. Both led a rather pampered life.

Spinoff of my hate for the general in the Caddy EXT thread. Let’s hear about the good trucks that made you money working. Your personal rig or company rig, and the trucks that cost you dough. Maybe throw in what finally killed them.

96-97 Chevy 1500. Not fit for farming duty. Ate front end parts at a alarming rate not that you could tell because the clapped out interior drowned out any other noise. Interior door handles were purchased in gross. Went through 2 trannies in 140k. Finally parked it when the doors sagged so bad they wouldn’t close. Heinous piece of garbage.

You’re blaming the gmt800 platform for what a gmt400 did to you in a notoriously abusive use case; your playing field is all sorts of slanted.

I can agree that the GMT800 is the same as the 400 in the respect of not being fit for farm duty.
The 800 platform is considered great by those who owned the 400, not anyone else:flipoff2:
Seriously, the only way they are cheaper to operate than the other 2 brands is if you’re doing the work yourself. If you’re paying to have it done all the discounts from the “cheap to buy” parts are used up in labor and the frequency you have it in the shop. Unless you can tolerate shit not working properly a lot of the time or the check engine light being another interior light.

if you're looking for a flawless vehicle that never needs repair, and lights on the dash induce panic, then something that the newest one is 18 yrs old is probably barking up the wrong tree. (you might be able to find that in a camry or accord)

universal truths of the gmt800 after 150k:
the abs light (solder failure in the module) will be a permanent fixture on the dash
the gas gauge won't work accurately consistently if at all.
stepper motors in the gauge cluster will fail on 03-06 trucks
you might chase intermittent CEL for 02 sensors and knock sensors; both of which you can drive with forever with minimal downside; but theyre also < 2 hr book time labor.
the front diff might whine but they usually take until 220+k to fail unless abused/ awd/ driven in auto 4wd all the time ( same for the t-case).
climate control temp adjustment/ blend doors will likely need a few minor repairs along the way.

but outside of a few makes of japanese cars and diesels there's nothing out there that comes close to the number of gmt800's rolling around with 300k plus on the odo and in DD service on US roads today.

tuning out the cats to shut up the 02 errors can be done in HPTuners/etc. think I paid someone $150ish to do it for me, or you can mail in the PCM.

My 2002 electrical was flawless other than the cluster. My 04 driver heated seat has a mind of its' own, and randomly squawks a fake brake system issue, but seems to be OK other than that.


it ain't my 2006 civic, but its way more comfortable/ way more features/electronics, etc. Like others said, just about anything that comes up is well documented and parts are dirt cheap. Except the trans, I couldn't justify spending $3-5k to have a trans rebuilt on a $3k truck that was rotting away. At that point, they're throwaway vehicles IMO. Probably why 5.3's are $400 all day around here

Oh yeah- add 03-06 heated seats will short within 5-7 min of activation to that list. (99.5-02 usually work till you wear through the seat to physically break the heater grids)
 
This just popped up on my IG and fits this thread. :lmao:
the comforting yellow hue of that ABS light just feels like home.

Airbag light however is a potential indicator of why its a rattle trap; but i suspect its most likely that the main ground on a bodymount by the frame that's now primarily bluetooth due to road salt.

mine's brand new last winter. worked flawless for a month? then it got all glitchy in the summer:laughing: dunno if it's the cheap pad, or the switch. so I'll ignore it till summer then probably just unplug it till winter comes again

It's too bad you can't make the ABS light go away, nor the stupid TPMS. Shoulda had the guy who rebuilt my cluster put some electrical tape over them or something. Owell
 
TMPS light can be made to go away by replacing the PDM (passenger door module). At least on the '05 Yukon Denali we had, there was one PN for the module whether or not you had TPMS, and it needed to be programmed for the TPMS to work. I had to replace the module and never had it programmed, and no TPMS light.

We bought it in 2010 with 90k, sold it in 2021 with 170k. Had a few minor issues along the way, but overall it was a great vehicle. We liked it enough that we replaced it with a newer one (2018).
 
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.

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)

Bullshit. First off if we are including cars i bet crown vics running around with that well outnumber the gmt800. Id bet the number of new edge mustangs are close by percentage of production in proportion. And id say ford trucks outnumber chevrolets here about 2 to 1. Probably because people here actually use their trucks for trucks. If anything there are more gmt400s left here than 800s and i live in the south. But the 800 just rusts out that and is such a big piece of shit that an older generation truck outlives it.

My claim is based on salvage auction searches; totaled GMT800 chevy's with 250k+ outnumber similar vintage ford expos/fjuan fiddys with the same mileage by at least 10:1. the local marketplace observations seem to support this too; Fords seem to die (or for some reason stop being listed for sale) between 180 and 210k ( 5.4 eating itself by the cam phasers?). If you broaden the scope beyond half tons to the superdutys it would probably close the gap up a bit, but the 6.0 and 6.4 don't really help the cause there at all.

I might concede to you on the panther platform, but it's not a truck, and taxis and a handful of traveling salesmen are the select few who piled miles on them. the cops crashed a bunch of them, grandparents have a lot of them in the garage with under 100k; so it might not math out either.
I don't think i've seen a new edge mustang on the road thats not a full blown race car in years, i didnt think the v6s which made up 60-70% of production were highly robust, but a copart search could yield some data there.

If you can get your 1st gen tundra to 300k before the frame rots out from underneath you it would probably be a contender.

I have had several new edges north of 300k on the original drivetrain and they are still all over the roads here and marketplace too in varying states of tried to trun my 250k+ miler into a racecar. The best new edges so far for me were my 02gt at 300k plus and an 01v6 that i bought for 200 bucks with 450k plus. I say plus because the odometer was one of the two things that no longer worked:lmao:. As for panthers well there are alot of gms in garages with sub 100k the ex cop cars are all over in private hands and they mostly started their private lives with 200k or more because they were cop cars or taxis or both.

You're looking in the wrong place for robustness is what im getting at. You are looking for what is dead or in the junkyard people want rid of. Im going by what is still running and good enough people DON'T want to offload them. Same applies for the gmt400/f150 claim. Around here they get hit or rusty they get fixed because decent rig. The gmt800s go to the scrapper because nobody can afford that rust repair and the engine is the only good part of the truck.

OK, your anecdotal evidence is better than mine i guess???

So if i got this straight, you believe fords outnumber chevy's but aren't crashed at the same rate??? ( almost all of them (parked cars being the exception) drove to the scene of the crash)

I'm at least telling you I've looked at some data points; you're telling me about 2 mustangs you drove and what you think about panthers (which, again, both aren't fucking full size trucks. )

You understand the difference between just idling along road speed vs having power put through it, right?

Congratulations you already forgot the whole point of the reply was to this claim right here. That the 800 is the most reliable and common high mileage dd out there short of a camry or a diesel. A car in a salvage yard is no longer a dd. Nowhere in there does it say dd doing full size truck things. Especially as if your dding it 99% of the time the bed is hauling nothing but a cooler maybe and some sailboat fuel.

If we are talking dd then anything goes. But for the record i would 100 percent bet there are more fords still kicking as dailys then gmt 800s. I put 50k a year on my daily no matter what it is and i havent had a gm product survive more than a year yet. Because again im looking at what i see on the road and i spend alot of time on the road.... Not staring at auction pages:flipoff2:.

This will be my last response on this subject because while i havent been shy about derailing this thread, this tangent is getting ridiculous.

you got a personal stake in this debate? was your great uncle a member of the Ford family or something?

In the entire states of VA and Md (iirc, the latter being your home state)- Insurance Auto Auctions has a total 28 99-06 expeditions, & F150's with more that 249k there are 70 GMT800's up to half ton- same parameters so just under 3x.
open that search up nationwide it's 761 GMT 800's to 318 Ford/lincolns so 2.5:1
( drop nationwide parameters to odo reading of 150k-249k = 848 ford/lincolns and 1412 gmt800's = 1.7x- much lower delta)


so that statistical regression says the gm's outlive the blue ovals. Again, everything drives to the scene of the crash and the majority of them were on the road within a yr.





now here's a hornets nest I probably shouldn't kick, but what the hell- It stands to reason that perhaps ford owners aren't letting their shit get totaled when they get hit because its worth about 40% less than a GM, and hard to get a functioning vehicle for the values assigned:

from kbb today ( not that kbb is great but it's what an insurance guy will use to make you an offer on your totaled junk):
1707962048444.png



so there- i'm mic-dropping on this tangent now- apologies to all who have endured it.:flipoff2:


Edit: there are exactly 18 new edge mustangs with 249k + in the US and 6 camaros, firebirda & vettes in new edge yrs, and 35 99-06 panthers nationwide with 249k that have been totaled, and await new auction winners..

They gotta be seriously fucking mismatched to do anything to an open diff.
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.
