My 1935 has a all new Mustang II front with new Michelins (been sitting off car for years). Had balanced by Pat Goss' Garage on their trick machine and aligned by front end shop with excellent rep. On occasion, about 50% of time if I let go of wheel will get slight shimmy that goes away when I regrab wheel. Don't feel much when holding wheel. Any suggestions?

Try driving on a freshly paved road & see if it still happens.

Check to make sure everything is tight {tie rod ends. ball joints Ect...} check the wheel bearings.



If it still does go get a load force variant balance to see it the wheel(s) is some how screwed up.

Thanks I did notice last night that the tie rod ends don't have cinch nuts but I can't imagine the tie rod ends moving that much but anythings possible. I just hope I can maintain the toe in adjustment when I unscrew to put on the nuts.

You mentioned that you have an all new MII front end. Check the lower control arms and make sure they are parallel to the ground when at rest. If not, you may be experiencing bump steer, which can be confused with tire balance shimmy and general steering shimmy. Some can be adjusted (Chassis Engineering) and other not (Heidts).

It's a Heidts. I put it in according to instructions and the lower arms arms are parallel to the road. If it was off, couldn't one change the spring height to raise or lower the arms? It drives perfect except for this slight shimmy. I think your right that the type of road surface affect the amount of shimmy. On some roads there is none.

[gdubstub]

You can always adjust by changing the spring height, but Chassis Engineering has an adjustment at the top of the tower for setting ride height.

If your lower control arms are parallel, you're fine...it's something else

Thanks. I drove it last night and was fine on certain roads. I'm thinking it's the balance on the tire except it doesn't get worse at speed and at 65 I feel a slight something, but not really shaking, in the wheel but the mirrors are all rock solid. I think first step is to double check balance. I bought the front Michelins new 10 years ago but they basically sat on the car. Maybe they took a set although that should show up on that high dollar Hunter balancer.
