on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and joint 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.
1. Power steering gear through left wheel opening.
2. Power steering gear mounting bolts and nuts.
-
Tighten bolts to 80 Nm (59 ft. lbs.).
3. Inlet pipe and outlet line fittings and seals to steering gear.
-
Tighten fittings to 27 Nm (20 ft. lbs.).
Inspect
-
O-rings, replace as necessary.
4. Pipe retaining clip to steering gear.
5. Raise frame and install new rear frame bolts.
6. Remove jack stands.
7. Connect pinch bolt at the intermediate shaft.
8. Stabilizer shaft through the left front wheel opening.
9. Nut to tie rod end at the steering knuckle.
10. Insulator clamps.
11. Insulator clamp bolts.
-
Tighten bolt to 47 Nm (35 ft. lbs.).
CAUTION: When installing the intermediate shaft make sure the shaft is seated prior to pinch bolt installation. If the pinch bolt is inserted
into the coupling before shaft installation, the two mating shafts may disengage.
NOTICE: Set steering shaft so block tooth on upper steering shaft is at the 12 o'clock position, wheels on vehicle are straight ahead and set
ignition switch to LOCK position. Failure to follow these procedures could result in damage to the SIR coil.
12. Left stabilizer shaft link bolt.
-
Tighten bolt to 47 Nm (35 ft. lbs.).
13. Right stabilizer shaft link bolt.
-
Tighten bolt to 47 Nm (35 ft. lbs.).
14. Left tire and wheel assembly.
15. Lower vehicle.
16. Fill with power steering Fluid. Refer to CHECKING AND ADDING FLUID.
17. Bleed air from system. Refer to BLEEDING POWER STEERING SYSTEM.
Inspect
-
For leaks. Refer to STEERING TESTING AND INSPECTION PROCEDURES.
Adjust
-
Toe as necessary. Refer to TOE ADJUSTMENT in WHEEL ALIGNMENT.
Checking and Adding Fluid
Power steering fluid level is indicated by marks on a fluid level indicator on the fluid reservoir cap.
NOTICE: When adding fluid or making a complete fluid change, always use a fluid which meets GM specification. Failure to use the proper fluid will
cause hose and seal damage and fluid leaks.
If the power steering fluid is warmed up, about 66° C (150° F) (hot to the touch) the fluid level should be between the HOT and COLD marks. If the
power steering fluid is cool, about 21° C (70° F), the fluid level should be between the ADD and COLD marks.
Drain and Refill System
The power steering fluid replacement procedure is a two-stage process: first, flushing the old fluid from the system with new fluid; and second,
bleeding the system to remove any trapped air. The following two sequences outline the steps in each procedure.
1. Raise the front end of the vehicle off the ground until the wheels are free to turn. Refer to VEHICLE LIFTING.
2. Remove the fluid return line at the pump reservoir inlet connector.
3. Plug the inlet connector port on the pump reservoir.
4. Position the power steering fluid return line toward a large container in order to catch the draining power steering fluid.
5. While a second person fills the reservoir with either standard power steering fluid GM specification 16 ounce or 32 ounce or optional cold climate
power steering fluid GM specification 16 ounce or 32 ounce, start and run the engine at idle.
6. Turn the steering wheel from stop-to-stop.
NOTICE: Do not hold the wheel against stops while flushing the system. Holding steering wheel against wheel stops will cause high system
