The proper size shim is the one that gives you about 8 inch pounds of preload on the pinion (not including the carrier) using new bearings when the pinion flange is torqued to 150 ft lbs. It is a bit of a PITA to find out which one is the right size.ob0ne said:Somebody knows the recommended thickness of the pinion shim for 4.10 ratio?
Also, what means TLCA number ? I have chosen 999999999. Made a mistake?
