(0.178-0.381     mm). If backlash is within specification, go to step 5. NOTE • Moving shims from left to right (as viewed from the pinion shaft) increases backlash. • Moving shims from right to left (as viewed from the pinion shaft) decreases backlash. 4 Move shims from one side of differential to other side to set backlash (see paragraph 5-17). 5 Torque screws (1) to 85 lb.-ft.  (115 Nom). 5-150
