Steering wheel 'wobble' at 45-50 MPH

I noticed recently that between 45 and 50 MPH I get a shimmy/shake/wobble in the wheel. Going absolutely straight, it's not there, but just put a bit of twist on the steering wheel in either direction and it shakes back an forth.

Any ideas? I don't think this is what others have referred to as "Death Wobble", but I'm not sure. I am taking it in for tire balancing and alignment this weekend, but thought I would ask first so I know what the real experts think.

The tire balancing/alignment should fix all your problems unless you have damaged wheels.

An alignment won't help, it's either a bad tire, an out of balance tire, or the wheel is bent or damaged.

I hope you're right. I've never had a tire so out that it caused the steering wheel to have a rotational vibration, but it sounds reasonable. The weird thing is that I don't feel it anywhere else (dash, seat of the pants, floorboard, shifter, etc.) I'll report back after the balancing.

thx again.

I had the same problem on my TJ, I changed the track bar, and got a adjustable one from teraflex, that solved the problem, I have a 2" lift on my jeep.

I had the same problem after my lift. I changed out the front driverside tire with the spare and...problem solved. Also check that the trackbar is tight (75 ft-lbs, I think).

The loose trackbar didn't cause the vibration, it merely allowed it to develop. Trackbars don't by themselves start vibrating... but tires and wheels do and when the trackbar is loose, it can let the front-end start shimmying even to the point of Death Wobble. Replacing the trackbar with a newer one only masked the symptom like holding down something tighter that was trying to move around on its own. Let go and it starts up again.

i just installed a BB, 1" BL and MML. for the first couple of days i had the tires i'd been using for a year (31" bfg at) and everything was ok. when i put the 33's on, then i started getting a wobble at about 45mph. my rear tires are new, but the fronts are used. i guess i'll try the self-alignment write-up on 4x4xplor. if that doesn't fix it, i'll have to wait and see if new front tires will fix it. hopefully it's not one of my new wheels outta whack.

The exact same thing happened to me the other day. I drove straight to the tire shop and had them rotate and balance the tires. Fixed it.

Just went through the same thing, balancing and alignment didn't help, but one tire was worn unevenly, replaced that and all is well.

I was going to start the same, identical post. Now don't have to. I noticed my 'shimmy' right after I took out my 2" spacers and installed 2 1/2" springs. I did the 'doityourself' alignment and adjusted the track bar also. Still got the slight 'shimmy'. Next is the re-balancing.
