I have nearly the same story. I have had a vibration in the front for a little while now. I did notice a little cupping on the front tires and thought that might have been the culprit. I had though I was just overdue for a tire rotation , not yet being familiar with the BFG AT KO's needs.
So today in preparation for an upcoming expedition, I rotated the tires. Upon jacking up the front I found the LH wheel bearing was bad. There was quite a bit of lateral movement.
This is the hub assembly that was replaced under warranty at 28,000 miles. I now have 56,909 miles and it failed again.
I purchased a NAPA hub assembly for $175. I comes with a ABS sensor, but does not come with the rubber o-ring seal that goes between the hub and mounting surface. Mine was still pretty good , so I reused it.
Those of you capable of changing your own brakes can handle this job. It is not hard. The socket needed for the axle nut is 36mm. It needs to be a deep socket. You will find that a 1 7/16" socket is only .020" larger and works just fine. I found I had neither in a deep version, so had to invest in one. The standard ( 1 7/16 ) socket was $6 cheaper than the metric socket. Guess which one I bought?
The socket was $24.
I pulled the caliper, caliper bracket, rotor and then used a gear puller to break loose the axle shaft after removal of the nut. Three bolts to take loose the hub assembly and three mounts for the sensor wiring to remove.
Everything went well and Hopefully this NAPA hub will outlast the right hand side which is still original equipment.
Summary: If you feel a vibration in the front, don't assume tires. Consider checking your wheel bearings. If you find a bad one , don't be afraid to fix it yourself.
