Rub Issue

I have been having issues with death wobble lately. This weekend I took off the control arms one at a time and installed bigger bolts that are the correct size to eliminate bolt wobble. Yesterday I noticed when I turn full lock right the tire rubs against the lower control arm; this rubbing doesn't occur full lock left. My jeep is a 2012 jku, 2.5" lift, stock control arms, and stock wheels/tires. It was involved in a wreck however the frame was straightened. Could it be that the frame wasn't straightened properly so the axle is at an angle and that is both why I have bouts of death wobble and a rubbing issues. If I get adjustable control arms upper and lower for the front could it fix both issues? Any advise is appreciated and helpful. Thanks!

Sorry *full lock right*

so you have it lifted with no front lower control arms and no adj front trackbar to center the axle? your factory bolts were fine, not sure who told you you needed bigger bolts.

I did the RK 2.5 stock mod kit. I have an adjustable track bar and adjustable drag link sorry forgot to add that. When I removed the control arms to inspect the bushing, the bushing sleeve had grooves that started to appear from the factory bolts and there seemed to be a little bit of play so i upgraded to 9/16" on the lower control arms only and it seemed to eliminate some slop in the bushing sleeve.

if you have an adjustable track bar, it's possible they did not center your axle - I believe there's a write in the stickies on how to center it.
I always loosen all my control arms when making suspension adjustments - just to allow anything to move into it's sitting position. also so I can shake it and make sure any possible binding is eliminated.
Do you have a rear adjustable track bar? it's not needed because as soon as you load the rear it off center... but I'm a bit ocd that way
 
those rk springs probably gave you close to 3" up front. more than likely your caster is off. you own a torque wrench? check torque and rotate your tires and some front lower arms. so is this a shimmy or actual death wobble?
 
x2 - once you check other things you'll want to make sure your caster is correct. - also a write up in the stickies on how to do it

Actual death wobble. It only occurs occasionally and when hitting certain road to bridge transitions on a highway that is also curving to a side. So you recommend torquing, rotating my tires, and getting a set of lower control arms?

Could the wrong caster be the cause of the rubbing?
 
you are sure your axle is centered? it moves when you drive, just dont know how off it is or centered.
 
I would first check the track bar bushing and assuming you have the rk track bar, the heim joint at the other end. Check the track bar brackets for wallowing as well, if all looks good retorque. Also check ball joints for play. Wouldn't hurt to check the drag link ends and tie rod ends. As far as the rubbing, what's your tire size and wheel back spacing?

just noticed he had factory rims and tires
 
sounds like the axle is just shifting to the drivers side and rubbing. i'd be more concerned with the death wobble. good luck fixing your problems.

3 options for that: center the axle, add a washer to the steerstop, add wheel spacers.
And I too, would be more concerned with the death wobble.

I was having this issue on my shitty procomp 2.5 lift. The reason it wasn't rubbing at full-lock left is because the drag link was hitting the sway bar before it could actually get to full lock left. Which smoked the ball joint in the drag link and gave me death wobble, which smoked both ends of my stock track bar and my ball joints. So, at 1500 miles on my Jeep, the dealership along with 4WP decided that it was somehow my fault that they conned me into knowingly paying WAY too much for a junk lift because I thought I was getting a warranty... so, after proper end links (instead of spacers that drop the sway bar right into the way of the drag link), a new track bar, a new drag link and new ball joints I have fixed the problem and rag on that dealership and 4WP at any given chance.

Long story short. Make sure your drag link isn't contacting your sway bar which would stop it prematurely from reaching full lock left.

ahh good point, I recall a previous post here about this--maybe it was yours?? but also another item to check
 
Nope. Wasn't mine. That's a problem that I had to find on my own after both aforementioned parties couldn't figure what could be possibly causing the problem... :rolleyes:

i had this same issue as well for a bit. my rock krawler front lower right arm was getting in the way. i fixed the rubbing issue by getting the EVO front lower arms. they prob allowed me to get my caster right which prob made a difference. they were the only things i changed out of my set up.

Can I have your factory bolts? I'll pay for shipping :yup:

Did I read correctly that you have an RK track bar? Is it safe to assume it's your driver side tire that's rubbing at a full turn to the right? If so, your track bar is set too long and your axle is shifted to the passenger side of your Jeep.

Yes, have since had a front end alignment unless me taking off the control arms one at a time threw it off.

^^correct stock wheels and tires.
