Shimmy/wobble in rear

[Jaysonb]

I don't think that bad wheel bearings are going to give you the end play that you have. You should pull the diff cover, and have a buddy push the axle in and out, while you look at where the end of the axle meets the cross pin. Something in that area is most likely causing your excessive end play. Look for damage or excessive ware on the axle ends, or the cross pin, or the c clips.
