that should buff right out
 
Camber change on a Cherokee is almost always bad news...

You guys still finished, right? Pretty awesome that you could fix it or had spare parts to keep going.
 
All it needs is to adjust the camber.
 
The world's first IFS XJ

Got any pics of it while it was airborne?

Yep. BITD official pulled us up out of the quarry to a place where our team could get a welder in. The official sat and watched to make sure that only the 3 banded people worked on the car or even touched any tools or parts. We pulled the housing out and got it aligned the best we could and I used a stick welder on it. I had to fill a lot of gap. Then I welded some angle and other scrap over it. Personally I didn't think it would make it the 15 miles back to main pit...but it did! It took out our front shocks so we had to use our spares, busted 1 front brake line, and a lower control arm.

We had also been having fuel delivery issues all day and the motor quit about a mile from the pit in that big nasty silt bed. The fuel filter was totally plugged with foam from the cell. Fixed that, did a lot of digging to get unstuck, and got it back to main pit. Did a little more welding and we went back out and finished. I cannot believe the repair went 150 miles. We will take the finish. I think we were the last finishing Jeepspeed.

Car was working awesome too. Started 17th and we had passed everyone and were running in the front when it happened.

It wasn't anything major. Spectators said maybe 2-3 feet in the air. And it was soft gravel so there was no big impact. We bent that housing at the MORE race in December and I think it was fatigued. It was straightened and checked for cracks, but... There was no reason it should have broken at that spot on the course.

wow, that sucks but it's awesome at the same time. Glad you finished - keeping the old housing to hang on the wall at the shop?

Might just be me, and I might be talking out my ass, but it looks like the crack is right where the end of that UCA mount gusset lands. Any chance it was weaker there due to hardening from the welding resulting in a weak spot that could start a stress crack?

Heck no! I'm burying it so no one can see my nasty welds!

I'd say you were pretty close with that. There were actually a few things there. Currie added a gusset underneath after we bent it, but the gusset stopped short of the LCA mounts. IMHO it should have gone from mount to mount. So any flex was now concentrated on a 2" section on each side where there was no gusset on top or bottom. It broke about 1/2" from the LCA mount. If you look hard at the second picture you can see where the truss ends about an inch or so back from the break.
 
Thats ugly. Great to see you pull a finish out of it.
