Default Low speed wobble

I have heard about steering wobbles mostly high speed "death wobble" but after searching havent found anything on low speed wobbles.
At low speeds under 40mph i am getting a decent amount of wobble in my steering wheel. As I go faster it settles down w/ no problems.
Any ideas?

Threw a weight from a front wheel? Maybe some mud buid-up in the backside of a front wheel? These are the easiest things to check first.

Don't forget look for evidence of a missing weight on the back side of the wheel, too.

No mud and all weights appear to be intact, and there are lots of them.

Default Great Name!

I got a low speed wobble(shimmy shake), and found the front trackbar to be the problem.

Get someone to turn the wheel left and right against the play, (engine off) as you put your hand on the trackbar, and feel for movement...... Tighten it down. I think specs call for 145lbs. The big thing is to get it to the point where you don't feel it move around .

It could be a few things, wheel balance is another factor, castor at 6 degrees is a good number for stable behaviour, and the same air pressure in both tyres. Another person had rear control arms that weren't tight, and caused wobble. Then check the steering stabilizer, but it is last on the list, as it is a band aid to a problem.

Good luck and post back your findings!

BTW... Your Jeep sounds like the cats meow!!

wheel balancing or uneven tire wear. that's my guess.

Did it just start? Mine did the same thing and I had to use patch weights to get them to balance now it's perfect.

Low speed wobbles are typically tire and wheel related for sure. I'd check for a seperated tire.

Check also aligment. Tires could have worn sufficiently to see whether the alignment is incorrect. Thus at slower speeds the tire might start to follow a slightly different path than at higher speed. This occurs due to the rotational inertia of the heavy tire.
