What you need to replace your rear wheel bearing can be bought from IMPCO (1-800-243-1220)for$36.00. Their catalog has a picture of it. I have one and it looks exactly like it, and I have used mine a few times. Their cat. description states"REAR AXLE SPLINE SOCKET Necessary for the replacement of rear axle bearings. Use to remove and install bearing nut." IMPCO is in Van Nuys CA. 91406-1321. E-mail:WWW.************************ Hope this helps you.
