Odd Steering Wheel Vibration Question (3 Viewers)

[PhillipJFrye]

So I've got a steering wheel shimmy that only appears at 70-75 KPH. No vibrations slower or faster. Shakes less when accelerating, more when coasting, about a half inch shimmy travel each direction on the steering wheel. What kind of gremlin is this?

Vehicle is my 2000 HZJ78 with a 2" TT suspension. 33" tires on 16"x10" rims.

Opinions, advice, polemics are all welcome. Thanks!

Any shimmy I look for loose steering components, deformed tires then bushing conditions. 9/10 time these will be your problem.

an easy thing to try is a different set of wheels and tyres on the front to see what happens to the shimmy

First thing I would check is adjusting/tightening the tie rod ends, then if those are good, I would check front bearing preload to make sure there is no play.

tire balance, uneven wear on tires can contribute, but the above are the primary reasons. Hope you are able to resolve quickly and easily!
