Installation Procedure

Tools Required

J 37292-B Tear-Away Axle Seal Protector

In order to complete the installation, observe the following assembly tips and reverse the removal procedure.

Assembly Tips

Important: 

   • Before installing the right side drive axle, be sure to install the J 37292-B . Refer to Drive Axle in Drive Axle On-Vehicle Service.
   • Line up the flywheel to torque converter marks made at disassembly.
   • Torque converter to flywheel bolts should always be tightened twice. The final torque should be 62 N·m (46 lb ft).
   • Check the adjustment of the shift cables. Re-adjust as needed.
   • After installing the front wheel and tire assemblies, torque the wheel nuts to specifications. Refer to Wheel Installation in Tires and Wheels.
   • Check and adjust the fluid level as needed
   • Road test and check for leaks.
   • When installing the transmission to engine block brace, tighten the brace to engine bolts first and the brace to transmission case last in order to avoid pulling the transmission case out of line.
