Vibration

[seaglen7284]

I have an 06 KJ with the 3.7 auto, it vibrates at idle, at 35 to 50 mph and anything above 65 mph. I like it in the steering wheel and when im above 65 on the highway it feels like it wants to drift when i hit bumps. I has it looked at and a shop told me that all the wheel bearings are fine and the suspension is fine. What else could it be???

Alignment, motor mounts, bushings maybe cv axles.
Does it pop when turning or make a whirling noise? At idle when you are parked? Maybe even you R&P.

X2 as above..
Start by taking it in for a front wheel alignment and have them check over the front end carefully!
Inspect ball joints all the bushings looking for cracks, and have them check it all over as above with a fine tooth comb.
What is your rpm at idle and how many miles on this KJ?
