1. Remove steering gear from vehicle.
2. Rotate stub shaft (40) back and forth to drain power steering fluid.
3. Remove adjuster lock nut (48) from housing (20).

CAUTION: Always use the correct fastener In the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion Inhibitors) on threaded fasteners or fastener pint Interfaces. Generally, such coatings adversely affect the fastener torque and pint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these Instructions can help you avoid damage to parts and systems.
