911- Help - wheel clang bang
Calling any gurus who may know something. I have family visiting me for Thanksgiving and while driving home from dinner tonight I heard a sudden noise metal clanging from the driver front wheel after going over a speed bump. I was in a neighborhood close to home and a guy heard the noise and saw me pull over.
He let me park in his driveway and take a look. We removed the wheel and first thought the brakes had disintegrated but they look great. Then figured wheel bearing (120k+ on them) but it was tight. Removed the caliper and rotor. Both look great. When I turn the bearing from the lugs, it would catch and not turn, then pop over and clang clang, catch again, clang bang, etc. But it doesn't do it in reverse. Spin it backwards and it works, then forwards and catch, clang bang. Ujoints are 4 years old and look great and tight.
I have to get my parents to SEATAC airport tomorrow and have no idea if it will work or not. I'm scared the Dana44 just grenaded out of the blue.
Everything else is fine: u-joints, brakes, drive shaft, etc. No leaks, or parts out of whack. We re-attached the caliper and wheel and I limped it home but it stopped doing it after a couple blocks. Could the shift collar be trying to engage the driver shaft? Would a vacuum leak cause this? It was dark so I'll go look again in the morning but any help you can give is appreciated. I live in Everett, WA so I'll read any responses by 7am PST. Thanks!
P.S. This is my DD and only vehicle. I was driving all day with them touring the region and had no problems. But been having a strange vibration at certain rpms and when braking that I can't figure out for the past year.

Bearings have some odd and strange failure modes, and you may have just found one of them. You can pull the cover, and see if everything in there looks good, if it does, it would replace the bearing......
