TESTING ON VEHICLE

  1. Raise rear wheels off ground. Shut engine off. Place shift lever for automatic transmission in "P" (manual transmission in low and transfer case in "N", if equipped). Grip tread of tire, and attempt to rotate wheel.
  2. If rotation is extremely difficult or impossible, differential is performing correctly. If either wheel turns relatively easily or continuously, differential is not performing correctly and should be replaced.

REMOVAL & INSTALLATION

The same procedure is used to remove and install Borg Warner differential as standard differential. See DRIVE AXLE - 7.5", 8.5", 8.875" & 9.5" article in this section.

CAUTIONDuring removal and installation of axle shafts, DO NOT rotate 1 axle shaft unless both are in position. Rotation of 1 axle shaft without the other in place may result in misalignment of 2 spline segments with which axle shaft splines engage. Difficult realignment procedures would then be necessary when axle shaft is reinstalled.

OVERHAUL

Borg Warner differential is serviced as an assembly only. Under no circumstances should differential be disassembled, reassembled, and installed in vehicle.
