Carnage share thread

[Brian1]

I bought a D44 TTB for parts many years ago and found this when I cracked it open. Every tooth on the ring gear was rounded/flattened over, I dont remember what the pinion looked like but it couldnt have been good either. Wound up selling the housing for big $ because it was the rare one with the bolt-on bearing/axle retainer.

A LOT. This is the words from the photographer “I don’t think I’ve ever witnessed a car disassembled before my eyes”

Zoom in on these and look at the fluids blowing out of things as their being exploded

The amount of energy released in those photos looks like the car was doing Mach 9.9 when it decided to yeet itself.

Yes. My friends rig. Doing hard trail stuff, water in 42 krawlers. Got it in enough of a side bind to fail the unit bearing.

Would the same thing happen on a traditional hub/spindle?

I must say, I feel like I have carnage in my life but holy shit you take it to another level…and the variety of carnage you post is impressive too

Most likely. The same night this happened, same hole, another guy in the group broke a GM kingpin 60 front knuckle in half. I didn’t get pics of that to share though

Probably from running dry for a long time.

I’ve heard of kingpin knuckles breaking. That doesn’t seem to uncommon. I’m shocked on the unit bearing though

The guts out of one of our ram assist steering boxes. The ram assist ram is a 2 1/2” double ended ram and still got enough force into it to explode the steering box

Was this before you started using the external servo?

 

[JR4X]

Nope. That was this summer. I think July the U4 stampede in NorCal.

Long story short. We put a wrong servo on the car and it didn’t do everything it was supposed to do. We were messing with stuff trying to figure out why our steering stopped being ideal. Dad hit a giant immovable object hard enough to do that to the steering box. That same box had been in the car for every single race from 2015 till July 2022. New box parts new servo new pump and we’re back to the steering we want. It cost us the podium too.

10-4.

Maybe I have missed what steering youre running since that thread hasnt been updated. Is it still the external servo & manual box, or are you running a powered box too?

Still turning power steering boxes, into manual boxes to get the ratio I need. So custom manual box, external servo, DE ram. There are no lines hooked to our steering boxes.

2011 up superduty unit bearing on a 4 wheel steering buggy. Pulled the threads out of the retaining nut and the UB came apart.

That looks like a 99-04 UB

 

[JR4X]

You’re right, definitely not 11 up like I thought. The hole in the drive hub isn’t big enough

 

[gt1guy]

When you crash so hard it rips the front axle out from under the rig and knocks the driver completely unconscious for a while. Put it together and got it on the podium 4 hours later.

Out of curiosity, how did the roll cage hold up? Sure looks like it took some serious hits.

Perfectly intact. Hit hard on the drivers side and didn’t deform at all. Score for good cage design and a little luck

That's one hell of a life span for any part on a U4 car. Does a chassis or axle housing even last that long?

Nope. We had disassembled it and inspected at least once a year and never found a single issue. After breaking a steering box a race from 2012 to 2014 not tearing one up in 7 years was worth the test. Axle housings last 4 years tops.

Bumping this post up.

Friend broke another Spidertrax 40sp stub shaft. Very similar to this one, but no pics.

Current tally is about 1 stub per year. Parts take 2 to 3 months to show up.

Something will have to be done because this obviously ain't cutting it.

Wouldn't using 05+ unit bearings and the Spidertrax big ass stub shafts that fit the big splines in those hubs completely eliminate that problem?

Spidertrax doesn't make anything that fits in a 05+ UB. They only do specific stubs that fit in spidertrax UBs.

Also, my friend's axle has Dana 60 kingpin outers, you can't just swap it to 05+ like that.

Branik makes the big ass stub to completely eliminate the extra drive flange parts.

Yup.

CTM did for a bit (they don't anymore) and Ouverson does too. RCV has big bells with a similar stub shaft (that's what I'm running in my buggy).

None of it is applicable to a kingpin axle though, and unless Sandy Cone makes steering shafts, I am pretty sure that Spidertrax is the best out there.

Sounds like your friend needs to build a new and different style axle if he's breaking the best of the best parts money can buy for a KP axle.

Agreed. But what am I gonna do, bitch at him ?
I'm just a good buddy and I'll help tow his rig out of the woods and put it back together when it inevitably breaks again.

Holy shit that had to be one heckuva ride..

Dang you guys are hard on parts!

That was a teammate of ours. RuffStuff sponsored Travis Riley going for the bad ride.

I did the same thing on the same day at the same place in my rzr though.

 

[bunk]

ouch !

 

[Wades_76_cj7]

ouch..

 

[ParadisePWoffrd]

those bruises from the sub belt?

I camped next to Travis at KoH 2021, nice guy. He had a bunch of youngsters at camp with him with raisined up Yotas. I think their dad owns a transmission shop and let them build in it. Gave me hope for some of the youth these days.

Thats a gnarly bruise, that one on the left looks low. Were his belts not snug or did he get thrown hard enough to get the lower belts that far down his leg?

 

[JR4X]

Lap belts but the clam strap holds them right there. I got spin cycled and the G force of it trying to fling me out of the seat put that much pressure on my legs. With my body I put enough pressure on the clam strap to bend the chassis where it attaches too.

Trav is a good dude. And those bruises are on me. I got slammed into the right side of the seat on initial impact. Belts were plenty tight that’s just where they happened to be positioned when they had to do their intended job.
