decrease preload.

Note: This is a preliminary check. Final bearing preload

check must be made with pinion shaft and bearing cage

22. Install pinion assembly in differential carrier

housing, using original shim pack or its equivalent

thickness. Use four pinion oil seal retainer bolts with flat

washers to pull pinion shaft assembly fully into carrier

24. Recheck the bearing preload making sure that

the reading is 13 to 23 in-lbs (0,15 to 0,27 m-kg/1,47 to

2,60 joules). If necessary, disassemble parts and add

shims to decrease preload or remove shims to increase

preload.
