steering wheel wobble.. Help

Just another suggestion...

I've got a Tundra as well and when I put on a plus sized wheel/tire combo, I got a lot of wheel shimmy at around 60. The reason I was getting it was that the Tundra has a hubcentric mount as opposed to lugcentric. The hub is 107mm and my wheel center bore is 110mm. Even though the wheel/tire setup was road force balanced with the Hunter GSP9700, the wheel was slowly shifting until one side was against the hub and there was a gap on the other side causing the vibration. The solution was getting 4 aluminum hub rings machined to take up the slack. If your setup is hubcentric you might want to check this out.

lovehamr,

I have not put an isolator in the steering shaft yet, but will end up putting one of those isolated u joints made by flaming river, if I havn't found the problem soon.
I do have plans to have the alignment checked and/or adjusted.
The headers Im running are FPA in washington, there were no clearance issues.

Bruce:
I have checked all fasteners that hold the rack to the frame, but will check again for bottoming out. I did check and retighten tiny set screws with loctite, at all locations of ujoints etc...
The tech guys at Total Control (Chris Alstons) have been very helpful so far as far as tests and adjustments.

I pulled my rear axles over the weekend, one of the axel bearings felt like it needed attention. They are getting replaced tonight. The pinion bearing felt great.

I dont want to do multiple changes between test drives, I'd like to pinpoint this sucker and find out exactally what was causing this.

Plan:
1)test drive with new rear axel bearings.
2)test drive with new shorter lug nuts (im currently using trans- am long style lug nuts approx 4" long)
3)Revisit rack and pinion mounting locations, and test for play
4) Have tires/wheels balanced while on the car
5) Revisit the alignment specs, test car for straightness
6) Replace entire braking system and spindle upgrade (Global West pro vintage set up)
7) Purchase a 12 pack of beer, and scratch my head some more.

More to come.
