RACK BEARING PRELOAD ADJUSTMENT
- Loosen the adjuster plug locknut and turn the adjuster plug clockwise until it bottoms in the housing. Then back off 50-70 degrees which is approximately one flat.
- Raise and support the vehicle safely to make the proper adjustments. Be sure to check the returnability of the steering wheel to the center position after the adjustment.
- Tighten the locknut to the adjuster plug to 50 ft. lbs. (70 Nm).
REMOVAL & INSTALLATION
- Raise and safely support the vehicle. Allow the front suspension to hang freely. Disconnect the pressure lines from the steering gear and drain the excess fluid into a container. Be sure to plug the openings.
- Move the intermediate shaft cover upward and remove the intermediate shaft-to-stub shaft pinch bolt. Remove both front tire and wheel assemblies.
- Disconnect the tie rod ends from the steering knuckles. Remove the line retainer, outlet and pressure hoses.
- Remove the rack and pinion assembly-to-chassis bolts.
- Loosen the front engine cradle mounting bolts and the lower the rear of the cradle about 3 inches, as necessary, then remove the rack and pinion assembly.
- If disassembling the rack and pinion assembly, use the accompanying illustrations as a guide and keep the following points in mind:
- Due to the complex nature of the rack and pinion steering gear assembly, special tools are required in order to safely service its' parts. If you cannot obtain the proper tools, do not substitute homemade versions, instead have the assembly serviced by a certified professional, or damage (leakage, improper steering, etc.) may result.
- All parts, especially fasteners, are of specific material, length, and strength. If replacement is necessary, use only the specified part number or the steering capability of the assembly will be compromised. Be prepared for the inconvenience of sparse parts availability.
- Fluid leakage is not necessarily caused by a seal. Often, the body of the housing around the seal has worn, or the seal has worn out the component that travels though it. Taking the time to reseal in this case may prove wasteful.
- Remanufactured and/or new units should be readily available from a local parts distributor or dealership. These units should be warranted and fully tested, so as to avoid the headaches caused by the above points.
- Install the rack and pinion assembly into the vehicle. Raise the front engine cradle into position and tighten the attaching bolts.
- Install the rack and pinion assembly-to-chassis bolts. Tighten the rack mounting bolts to 50 ft. lbs. (68 Nm).
- Connect the tie rod ends to the steering knuckles. Tighten the jam nut on the outer tie rod end to 50 ft. lbs. (68 Nm). Tighten as needed in order to install a new cotter pin. Install the line retainer, outlet and pressure hoses.
- Install the intermediate shaft-to-stub shaft pinch bolt. Move the intermediate shaft cover upward into position. Install both front tire and wheel assemblies.
- Refill the power steering pump reservoir.
- Bleed the power steering system and check for leaks.
- Lower the vehicle.
- If desired, have the vehicle's alignment professionally set.
