my 07 g.c. 1500 thunder road has a vibration that starts around 50 mph and continues to ..well i havent been past 80, so to 80, but only on light acceleration it does'nt do it on heavy acceleration,also if i hit a bump such as a road patch or an expansion joint at 55 or higher it "jitters" feels like the rear end hops and twists otherwise i have a ball w/this truck will sway bars help? any ideas? thanks

 

Start at tire balance.

 

yea balance checked this is definetly a drive train vibration but the wheel hop is more bothersome

 

Is everything tight in the drive train? If so I'd hit the dealer if you are still covered by a warranty. Even if you are not covered by a warranty I would still hit the dealer. It really sucks driving down the road and watching your wheel pass you as you come to screeching halt.

 

Does the current Recall on the front hubs effect your truck. I have an '06 and they replaced my hubs. I have a friend that is a mechanic for Dodge and he told me of several cases where a front wheel broke off while going down the road.
