Disassembly & Assembly: Axle: Disassembly

WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Many components and surfaces in the axle are precision machined. Careful handling during disassembly, cleaning, inspection, and assembly will prevent unnecessary damage to machined surfaces.

Remove the front drive axle assembly from the vehicle. For additional information, refer to AXLE ASSEMBLY - FRONT .
Attach the axle assembly to the special tool.
