took my new 05 screw (700 miles on it) to the dealer to get the roof rattle fixed and mentioned to them there was a slight wobble at hwy speeds...they added foam blocks to the roof and ended up putting 4 new tires on it - the wobble is gone and it rides a hellofvalot smoother too..it had goodyear wrangler at/s' on it and that is what they replaced them with - dealer said that sometimes they just get a bad batch and not everyone who has a 4x4 notices...

 

Thanks for the reply guys...I"m going to try a rotate and I'll torque all the wheels to spec.

I have been eyeing those Bilsteins for awhile now I may have to give them a shot. All in all this nibble is so much better than that vibration problem I was having. That made Happy Gilmore not so happy. I would drive and watch that bed do a dance in the mirror, and I felt like I was in a masaging chair.

I also did check out tire rack and two things jumped out at me. One was that the general tires are only $70 each so that right there explains alot. Second was that is the only tire available in that size, which is pretty interesting.

 

I have 305/55/20 TOYO Open Country's. Never had the nibble until I put these on. It seems change for the worse or the better every time I rotate and balance.(road force) Not acceptable to me. Do a search on nibble and there will be a lot that shows up.
