Thanks,,going past china frieght tommorow/willl stop and grab a 22mm socket...the manual says 16mm threads so i was guessing it would be in the 20,s for the nut...my drive shaft teeth corners / edges are rounded off so replaceing it and the cup.2001 38k miles...dont think prev. owner was much on preventive maint.
If you are replacing the cup, replace the shaft as well. A worn-into-new part will rapidly wear the new one to as bad as the old.
Shaft and cup need to be replaced together.
