Replacement
CAUTION:- Prior to removing any of the components incorporated in the steering linkage, it is imperative that the road wheels are in a straight ahead position and that the steering wheel is then removed to prevent the cruise control spiral cassette being wound up or damaged if the steering linkage is inadvertently moved or rotated.
- After refitting steering linkage components, the road wheels must be re-positioned straight ahead before fitting the steering wheel, do not reconnect the multi-plug to the cassette or fit tile trim pad at this stage. If, after the vehicle has been driven, it is found that the steering wheel requires re-positioning, remove the wheel. Re-align the drive pegs on the cruise control cassette by slightly rotating the upper part of the cassette in the appropriate direction until the pegs lie horizontal to the steering column.
- Fit the steering wheel ensuring that the drive pegs locate in their respective holes on the rear of the steering wheel.
- After final alignment re-connect the multi-plug to the cassette, tighten the steering wheel securing nut and fit the trim pad.
NOTE:
- It is important that whenever any part of the system, including the flexible piping, is removed or disconnected, that the utmost cleanliness is observed.
- All ports and hose connections should be suitably sealed off to prevent ingress of dirt, etc. If metallic sediment is found in any part of the system, the complete system should be checked, the cause rectified and the system thoroughly cleaned.
- Under no circumstances must the engine be started until the reservoir has been filled. Failure to observe this rule will result in damage to the pump.
- Metric pipe fittings are used with O-ring pipe ends on the fittings to the steering box.
- Follow normal O-ring replacement procedure whenever pipes are disconnected.
- Ensure that compatible metric components are used when fitting replacement pipes.
REMOVE
1. Park the vehicle on a level surface.
2. Prop open the hood.
3. Remove the filler cap from the power steering fluid reservoir.
4. Disconnect the fluid pipes from the pump. Drain and discard the fluid. Replace the filler cap.
Power Steering Lines:
5. Disconnect the fluid feed and return pipes from the steering box.
6. Seal all disconnected hose connections to prevent ingress of foreign matter.
7. Jack up and support the chassis front end with axle stands. Alternatively, raise the vehicle on a hoist.
CAUTION: Whichever method is adopted, it is essential that the wheels are chocked, the parking brake is applied, and low range selected with differential lock engaged.
Steering Gear External Components:
8. Disconnect the drag link from the pitman arm using a suitable extractor.
9. Remove the pitman arm, using pitman arm extractor MS252A.
10. Remove the pinch bolt attaching the universal joint to the power steering box.
11. Loosen the nut securing the tie bar to the chassis.
12. Remove the bolts securing the tie bar to the steering box and move the tie bar aside.
13. Remove the fasteners attaching the power steering box to the chassis side member.
14. Withdraw the power steering box.
REFIT
1. Refit the steering box to the chassis side member and tighten the four Nyloc nuts to 81 Nm (60 ft lb).
2. Refit the tie bar to the steering box, and tighten the tie bar securing nut to 81 Nm (60 ft lb).
3. Reconnect the pinch bolt, attaching the universal joint to the power steering box, and tighten to 35 Nm (26 ft lb).
4. Refit the pitman arm.
5. Refit the drag link and secure.
6. Lower the vehicle to ground level.
7. Remove the sealing plugs and reconnect the flexible hoses to the steering box.
8. Remove the sealing plug and refit the flexible hose to the power steering pump.
9. Ensure that the steering wheel is correctly aligned when the wheels are in the straight-ahead position.
NOTE: It may be necessary to remove the steering wheel and reposition on the splines to obtain this condition.
10. Remove the filler cap from the power steering fluid reservoir. Fill the reservoir to the oil level mark on the dipstick attached to the filler cap with the recommended fluid and bleed the power steering system.
11. Check the fluid level and replace the filler cap.
12. Check, and if necessary, adjust the steering box.
13. Test the steering system for leaks, with the engine running, by holding the steering hard on full lock in both directions.
CAUTION: Do not maintain this pressure for more than 30 seconds in any one minute, to avoid causing the oil to overheat and possible damage to the seals.
14. Close the hood.
15. Road test the vehicle.
