Differential Side Bearing Preload

NOTE:

Differential side bearing preload is controlled and adjusted by means of select-thickness shims sandwiched between the side bearing cups and the housing/cover.

NOTE:

For accurate results, differential side bearing preload must only be measured when the pinion housing assembly is removed from the axle.

  3. Install Torque Tool (special tool #C-4995A, Tool, Differential Bearing Torque) (1) to differential housing as shown in the illustration. Measure and record differential rotating torque. Differential rotating torque should be within 190-260 N.m (17-23 in. lbs.).  If rotating torque is below this range, disassemble housing, measure and install slightly thicker preload shims (1). Add thickness equally to both sides. If rotating torque is above this range, disassemble housing, measure and install slightly thinner preload shims. Remove thickness equally from both sides.
