I have a slight vibration in my steering when traveling straight and turning left. When turning right the vibration disappears. I have a 99 xj with 4.5" coils, lca's adjusted to 16 1/2 stock uca's, rock krawler adjustable track bar. Stock pitman arm and steering. Replaced both hubs and axle u joints. I am running 33-12.50-15 on alum wheels with 3.75 back spacing. It has been lined up recently and drives straight down the road. I replaced the bushings in the stabilizer also. I can't seem to figure this out.

When was the last time you had your wheels balanced?

Gee oh Dee

Axle u joint?

I don't have 5000 miles on the new tires yet. That would be another spot to check.

I have the same exact issues, gets worse turning left but better turning right at speeds around 45-50mph. Almost felt like a rolling death wobble which was weird to me. I chased this around and around until i finally got sick of spending money on keeping the tires balanced, at which point I put bb's in there to dynamically balance them but made it so much worse. Found out the original tire shop was ****ty and I had 3 bent wheels which is why they came out of balance so often.

So check for bent rims and re-balance your tires.

I am going to get the tires balanced in the morning. I will let you know of it works or not.

The problem is a 3 year old hub went bad. I checked both hubs last month when I had my u joints changed and everything seemed fine. But I guess they wear out faster than you think. The stock ones lasted over 150,000 miles and the new ones lasted less than10,000.

Timken bearings are where its at. 3 yr warranty on them

I assume it was the passenger side one..did it growl/whir at all?

dougfrompa

Drivers side. It had a vibration in the steering wheel and makes a loud hum or grinding sound. When turning right the noise and vibration quit. That was the only way I could really tell that something was wrong.

So changing the hub fixed everything? Ive had hubs go bad and didnt cause this issue

multiperpus

Bad enough and the wheel can wobble. Seen em bad enough that with a caliper not working proper the rotor started dragging on the knuckle.

TheJerm

Well me too but never caused the issues he had, one hub came apart when removing it and the ***** fell out, I just added grease and put alittle more torque on the axle nut to get me by
