So I have been hearing a loud humming noise coming from my front end the last 2 weeks. I finally jacked it up and pushed up on my wheel ( standing with the tire in front of me I pushed at the top of it). To my suprise it moved about an inch. I know that this is not a good thing but I am not positive what it is and how much it is going to cost me.I also noticed that when I spun the wheel the u-joint was also rotating with it even though the hub was set to "auto". I did alot of reading about needle bearing and such. Is it somthing that I can just replace the bearing on or is it the whole assembly? Is there a diagrame with a exploaded view or any instruction that I could take a look at? I need to do this this weekend I am afraid to drive it anymore.

Thanks

Either the ball joints or the main bearings. Lug nuts tight?

I would assume it is the bearing because of the humming noise you mentioned.

Yes the lug nuts are tight and so are the ball joints. Is it just one bearing that I can replace or is it the whole assembly? I have the tools and equipment to disassemble any thing. I also saw alot of grease on the u-joint

Sounds like the bearing.. It is a unit bearing hub, you just buy the hub and install. You will need a new yellow o-ring seal on the hub. Your bigger problem sounds like the outboard side of the axle shaft is heat welded to the hub/needle bearing. If that is the case you will need a new outboard axle shaft and u-joint. The needle bearing will be new with the reman'd hub.

Pull it off and see. I would not drive it with an inch of play. That is a lot of heat. Look for scoring on the axle shaft at the u-joint side where it rides in the hub needle bearing. Hubs are about $300.00 - $350.00, I don't know what the axle shaft will cost.
