Vibration

[TJNE]

I have a vibration from the right rear, it feels like wheel hop between 45 and 50 mph. I have rotated and balanced the tires and it is still there. What are the odds the rotor is out of balance? Has anyone else had this problem?

Have the rotor turned, check leaf spring bushings, check the rear shocks...

One common problem I’m familiar with is called “ frame beaming” (TSB 1844688). It’s a beam shake vibration that is usually felt in the seat and occurs between 40-60 mph. Severity of the shake may vary from vehicle to vehicle. The diagnostic procedure says to place 200-500 lbs in the bed and if the shake goes away, it’s “beam shake”. The TSB further states it’s a characteristic of the vehicle and that there is no fix (for the 2500/3500HD’s).

On my 03 crew cab I get a slight bounce type vibration at approximately 45mph when the bed is unloaded.. In the winter I run with four 80lb sand bags in the bed and the vibration is gone.
