Hi all,
Been searching around for info on what might be wrong with my M1009 front end - there's a lot of noise coming from something down there. It's intermittent, but noticeable.

My mechanic swears it was the passenger's side wheel bearing - which he replaced, and that seemed to help for a few days. I'm wondering if the driver's is having the same problem (seal on the hub locker failed, letting some dirty water in).

I've raised the front end and rotated the wheels by hand - they both make a little noise when rolling, but the passenger's seems to slow much more quickly.

How do I check the wheel bearings, to see if the driver's is full of crud, and to see if the repair on the passenger's side was successful? What do I do to see if it's in the front differential? Should I prepare to open up the diff and check it, or is it more likely something in the bearings/hubs?
