severe impact. permanent damage?


Recommended Posts

so i hit some jumps in my jeep and bent the front coil area so that the bumpstop is cocked forwards and the coil is bending inwards a bit and rubbing in the wheel well. the whole front end is dogtracking and i'm wondering if i can bang this one out. does this not happen to everyone?

I can't speak for "most" of the other members, but I'm a charter member of NAXJA as well as this place and a local club here in CT, I've been on a great many trail rides and such over the years, and I have never seen anyone get all four wheels off the ground. If you hit hard enough to bend a bump stop, you were going FAR beyond the capability of the vehicle. Maybe you aren't aware that the vehicles you see in the movies and those desert racing trucks are specially built to withstand "big air" jumps.

 

Photos would help, but my opinion is that you can't safely straighten a bump stop pillar. And if you bent that, there's probably a lot bent besides that. I am sorry to say that I think you trashed your truck.

coming from someone who has bent their axle, it doesn't necessarily mean the frame is junk. I thought mine was alot worse than it was....and I'm pretty sure all 4 wheels were off the ground (I know everything was out of the bed...)

 

 

 

 

btw, I drove home 240 miles like that...

Agree with Pat... at least on my TJ, I had all 4 off the ground (substantially if you believe the witnesses), bent the front axle tube pretty well, looked about like Pat's pic above, drove it home 180+ miles with bowed wheels... My tie-rod (heavy duty Currie) needed to be pressed straight again, I replaced the front axle assembly and other than some tweaked front fenders (from where the tires were shoved when when the bumpstops "failed") but nothing else structurally wrong with the rig.

i had a friend with a 00 cherokee we lifted and he jumped something(not sure what)but the impact was hard enough to bend the rf axle bumpstop but nothing else.we tried to pound it out straight but no luck.it still drove fine and didn't wear the tires any more than usual but every time he hit a hard bump it would rub the spring and make a boing noise so he eventually traded it in for a hhr.

It would appear that neither you nor Pat hit hard enough to bend a bump stop.

 

I'm betting the OP's unibody is bent.

nope. just hard enough to crack the uniframe where the steering box is mounted...apparently the steering pitman arm didn't turn or allow any give when I landed.

this is how it got bent.

 

this is the olemotive truck (my competition) getting the piss beaten out of it.

 

but in whistler you have all kinds of rich retired rally drivers and 4x4 enthusiasts all crammed into a small village so this kindof $#!& is going on all the time.

 

in the actual rally course there is a pretty decent jump that most vehicles land clean and undamaged. my boss's truck does it every year and he hasn't broken any parts.

 

the truck is in the shop right now and i won't be there untill monday, but everything seems fine. ball joints, bushings, trackbar, are all good except the bumpstop is angled forwards.

 

the lower surface of the rubber on the bumpstop is aproximately an 4cm out of place.

jeeze, that poor j truck. it could be how they are approaching it to, although high speed and off road are way different than the off road most of us do. but most people i'd waiger are hitting the gas just before the jump just like that guy did, if you come around the burm faster, and hit it at a higher speed you're gonna get more damage. that ain't good for any vehicle, and that j truck is not built to do it either.

 

i love at the badlands they've made a race around the whole park, it looks like a blast, but everyone that takes their rigs through it tear them up, its a whole different theory to build an off road rig for hi speed, than it is for tight trails, rocks, and mud.

My bumpstops themselves up front were busted in multiple pieces...

I've seen some good air time in Baby before, not something I want to do again though. My damage list wasn't quite too severe, mainly because I landed almost nose first (I found dirt in the Jeep letters on the header panel that wasn't there before), but did incur some pretty bad damage nonetheless. If your axle is crabwalking, there's something really wrong there, take a good look at everything you can think of, and even the things you wouldn't normally think of looking at.

so the ax15 is in and while we had it up in the air i got a pic of the bumpstop, and we pryed on it using a 5' tire bar.

 

it straightened it so that it no longer forced the coil to rub on the frame and it could probably go straighter but it appears that the coil bucket and frame are unbent.
