help with yet another vibration diagnosis

[mattmocarsky]

Please help. I own a 2000 XJ with a 3" OME lift. I recently started getting a vibration coming from the front end. It starts at around 60mph and gets progressivly worse with speed. If I put the truck in full time 4wd and engage the front axle the vibration stops. However it only stops when applying the gas, as soon as I let of the gas the vibration is back.

I have already checked all the linkages and balanced all the tires (tires are new). I also recently replaced my passenger side wheel bearing. I am thinking that the vibration could be coming from the other bearing? Any thoughts? Thank you.

Matt

Check your driveshaft and axle shaft u-joints. Make sure your lug nuts are still tight.
