I had all wheels off ground checking for a front end vibration. Both wheels in 4x4 seem to wobble. I took off the wheels and noticed the passenger side caliper was somewhat wobbling while the wheel was spinning.... Would this be wheel bearing? No noise and the bearing seemed tight when I had it off to replace rotors. (both sides)... New ball joints and axle ujoints last month.

Wouldn't I be able to feel play in the bearing with it out?

Thanks

 

Perhaps beearing is good and rotor is warped??????? Do brakes pulse when applied lightly? Does truck pull to 1 side when stopping - opposite side caliper is hanging and caused rotor to warp?????

 

Brand new rotors, ball joints, axle joints. No pulling or pulsating

 

Quick work!
