I'm just curious if anyone has replaced their wheel bearings. I'm the original owner of an 03 G35 Coupe, 6MT with over 200K. I changed the front wheel bearings and later the rears about 90K ago. Now it seems the front is making noise again. Has anyone replaced their wheel bearings at about 100K miles?

There are plenty of threads on people having to replace wheel bearings, very common issue. I've done one front on both my G and Fx and they're only at 60k.

You have to purchase the entire bearing hub assembly if you are talking about the front bearings. It's a bolt on replacement, easy to do.

Not so much. It just takes a lot more work.
