It has to be an 8.25 because it is oval shaped I did change the the pinion seal because it was leaking. Do you know if the bearings get greased from the rear end fluid?
Pat[/QUOTE I never worked on an 8.25, but on most the pinion nut has a crush sleeve under it and removing the yoke to change the seal can cause the pinion gear to lose it's setting to the ring gear.
