1993 XJS 4.0 Rear Bearing Rebuild and Tolerances ?
Hello…thanks to everyone for help as I have now finished rebuilding the axle stub bearings. I am now finishing up rebuilding the rear wheel bearings in the carrier hub.
I am a bit confused after reading various threads about how to set the bearing tolerances. Here’s my confusion:
1. When I disassembled the halfshafts from the hubs all I had was a bronze/phosphorus washer and a conical spacer - no shims whatsoever
2. I read that if all you are doing is replacing the bearings and races you can reuse the bronze/phosphorus washer and conical spacer, torque the axle shaft nut to 120 ft lbs and I’m done ??
So, I don’t think I need to do any measurements or add shims to make sure I have Zero end float ?
any thoughts or comments would be much appreciated
thanks
JB

Jaguar already did all the hard work of setting up that particular hub.
A fresh cast hub and new bearings require a painstaking procedure to get the bearing preload correct.
I prefer to let the factory do it when it is assembled. Bearing tolerances are tight so no discernible difference should be noted with a simple bearing relube or replacement.
