OK, so I rotated my tires yesterday and I also cross-rotated them putting the RF on the LR and the LF on the RR. RR went to RF and LR went to LF. Now, passing through about 40mph, the front end wobbles very bad. To the point I consider it unsafe and something is definately not right. It is a very large wobble and not a low frequency vibration or something like that. It definately feels like it's in the steering wheel/front end also. Here's the strange thing, it did not do this before the rotation. The back end of the truck (which is where the tires were) rode great with nothing unusual. I can't find any problems either. Should I get them balanced and see what happens??

 

Oh yea, I may be imagining this but I swear I think it's worse slowing down through 40 (brakes or no brakes) than it is accelerating up through 40...

 

Just friggin GREAT!!! While searching for my cause, I found a bad upper ball joint on the left side...joy!!! If you got any opinions though let me have them because I think the two are unrelated. Don't think at all the ball joint is causing my wobble.

 

Put your spare or another wheel/tire on "ONE" side of the front at a time and isolate the problem corner. It sounds like a wheel/tire problem if the rotation accentuated it.
