Just mounted my new 315/75/16 General Grabbers on my 07 H3 Tactical and, after fixing an upper control issue, got it aligned. I took a trip to the mountains to go snowboarding and on the way home there was a wobble in the steering and when the wheel is held straight the truck steers to the right. this is the 4th time in a year I have gotten an alignment, first with these tires, and it never holds. Any suggestions?!

 

Does the shop you get it done give hold a 1 year warranty? They should warrant their work to a year. I was told this by a local shop by me.

 

They do and have no problem doing it again its just a hassle. This last time it only lasted about 100 miles. Is there anything I can beef up in the front end to get this to stop? I have the torsion bars turned up and 35" tires. Could these factors cause too much stress and knock it out of line? I haven't heard of anyone else having the problem iether.

 

How about having an alignment done by somebody that has the requisite skills????

I'm just saying...........strike four and you're out?

 

I would throw in that if your steering rack bracket bushing is destroyed or just never tight by design, I guess, the alignment is changing all the time. It's like having a more flexible tie rod, which OEM are to a degree is why they get bent and then broke at times when getting knocked around and larger heavier wheels and tires add to that affect.
If you had upper a-arms replaced it would seem that would fix bushings and ball joint on that.
Like Doc says, it's time to go somewhere else but point out the bushing issue and have it checked.
I don't know about the wobble issue, you might try grabbing the tire and push pull at 3 and 9 angles and top and bottom. A bad hub bearing could cause some of that.
Of course an out of round tire could also be a factor but would seem to do it all the time.

Here is another one at about 10,000 miles.
