Ok so i just got my crap running again...its dana30 front, 8.8 rear disc, 4.10 gears, about 8" lift. adjustable trac-bar....all on 37 Mt/r

Ok so when im going down the road every thing is fine then it hits a bump and the damn tires start wobble violently back and forth..which is why its parked untill i can fix that..It has not had and alinement yet but really didnt mess with the tire rod. I know the 37" are a little massive for the dana 30 and its only temporary...thats why i dont want to spend alot of money on it..What do you guys think may be the problem...is the stock tie-rod turning in to a noodle? Would a heavy duty one fix this issue/ sleeving the stock one?
 
So you thru the 8" lift on and didnt mess with the tie-rods? Its got to be out of alignment.

I just had my first expereince with DW. I put a 3 or 3.5" lift on the XJ a year ago, no major problems, small vibes, etc. I had a professional alignment done afterwards. A few weekends ago I added a 1" spacer to the front and got some major wobbles. I redneck aligned it (poles and tape measure) and found 5/16" toe in. I had a HD tie rod waiting to be installed, so I finally put it on. At the same time, I pulled the alignment in to about 1/8" toe in. That seemed to help, but I still get the DWs, just not as frequently, or the threshold speed increased. I think I'm gonna change the wheel hubs, I had some outer edge tire wear on the driver's side since before the lift. Then get a professional alignment done. Everything on mine looks nice and tight though, so I'm a little, I'm worried I might need some adjustable LCA's to get more caster.
 
Best diagnosis method for DW. Have someone push back and forth from side to side on the front while you lay down and watch for movement in every connesction. Keep an eye out for movement in steering box, pitman, links, wheels, everything. Worst scenerio is a crack in the frame allowing steering box to move. Best case is something like a TRE. But you can't do this by yourself so don't even try...

ok so someone want to tell me what this picture is suppose to tell me? What you changes to leafs.???? thats nice and all but ill stick with my coils that flex.
 
it's just some sarcasm about death wobble...how not to lift the front of a leaf sprung truck
 
Nah, Brett's lifted his right....

I know the guys who put at least 1 version of lift on that cursed red thing...(though I think its been abandoned 3 or 4 times over by now)

You need to check for wear and then get an alignment....

if your front end checks out stearing stablisers can be your best friend on the hiway with anything over 35s:driver:

No.

No.

Stabilizers MAY HIDE the problem.
They WILL NOT fix it.

Thats likee shaving to get rid of crabs, sure you dont itch, but lose the skanks and the problem will actually disappear.

that's actually really true...:popcorn:
 
haha i think what it is is the facet one yes its out of alinement but the big one it think is that shi*ty stock steering and that those 37's are so big that when one tire hits a bump it makes the tie rod flex and causes them to fight each other....

i was not talking about crabs and the first thing i said was if your front end checks out . its hard on stearing componets when you run 37s or biger and your right small tie rods will flex.
 
If your at 8" of lift on an xj its possible your castor angle is all out of wack if you have adjusted the upper arms to compensate for your driveshaft angles...might want to check that out.
 
death wobble

well with long arms i got correct caster and there is not a front driveshaft installed right now so i dont think thats it!
 
Longarms have nothing to do with if your castor angle is right. You can have longarms short arms or whatever and have an incorrect castor angle...it depends on how your arms are adjusted. You can still have death wobble with a bad castor angle and no front driveshaft. Sounds like you need to do some searching on castor angle.
 
Brett, I thought you had re welded your perches to get you at 2-4 degrees, or did I dream that?
 
and now that i look at it why is one of my post from 3/21 coming after a post I made last night??? weird or is my computer just weird?
 
Ok for some reason im not seeing all the post in here, i didnt see the response to caster angle untill i logged out???? but yes i know what caster is and yes mine is set right.....
