The second hand Sure-Grip 8.75 489 rear-end in my Duster only spins one side at the strip, I assume that it is worn out. Since this is the cone-style, I cannot rebuild it so can I buy a new unit to put in the 489 casing?
Is a replacement a simple bolt in, just take clamps off and slide out old and in new? Do I have to take the yoke out?
