I Have thisvibration issue at 65 MPH, With my 2006 1500 QC 4X4 with 17 inch wheels, I was gettingthe vibration with the OEM tires but not as bad, They were pretty gone at 30 K, so I replaced the tires with new BFG Long trail from discount, still a vibration. Took to the dealer and they said replaced the front and rear drive shafts and said I have a bad tire. I went back to Discount and they replaced the tire. Still the vibration is there.Discount then replace all my new tires again with new Yakamas, still the vibration at 65, I took it back to the dealer and they said. Nothing wrong with the truck, you need toreplace your Tires with Michelin OEM tires to get rid of the vibration.

any one esle run into this?

 

Sorry for the multiple posts, I recieved a server error so thought the post did not go though

 

yeah i have the same prob except mines at and above 70 my truck came stock with 265/75/17 BFG long trails...and i swapped them out for some used 325/70/17 toyo open country AT's still the same prob...i have a 2004, 2500, QC, 4x4 with the 3.73 ratio.. i thought it might be U joints but if you got both driveshafts changed then i dunno....

 

Has anyone at either the tire place or the dealer removed the tires and spun the rims. When I had a vibration on my 07 I had the tires removed and the rims spun and found that one of the rims was just a slight amount out of round. Very little but enough to cause the vibration. Just a thought.

 

Have them check and make sure the driveshaft(s) are in balance, it's common for them not to be, even off the shelf...
