CAUTION: Replacement of nuts and bolts: Various thread-locking devices are used on nuts and bolts throughout the vehicle. These devices restrict the number of times a nut or bolt can be used.

1. Raise rear of vehicle and support on stands.

2. Remove rear wheel.

CAUTION: Do not suspend caliper from brake hose as this will damage the hose.





3. Remove brake caliper from carrier.
- Remove caliper spring clip.
- Remove guide pin dust caps.
- Slacken and withdraw guide pins.
- Remove caliper from carrier and tie to suspension mounting bracket.





4. Disconnect wheel speed sensor connector.





5. Remove and discard tie strap securing wheel speed sensor harness to brake hose clip.





6. Mark wishbone at pivot pin eccentric flange marker to aid installation.





7. Remove pivot pin nut and washer.

CAUTION: To prevent damage to parking brake cable, the hub carrier must be supported on removal from wishbone.





8. Remove hub carrier from wishbone
- Remove pivot pin from hub carrier.
- Withdraw hub carrier and support carrier on block of wood.

CAUTION: Note position of shims during removal. They must be returned to their original position during installation.





9. Noting their positions, remove shim from each end of pivot pin sleeve.

WARNING: ENSURE THE SPECIAL TOOLS ARE POSITIONED DIAMETRICALLY OPPOSITE ON THE SPRING AND THE ARMS ARE CORRECTLY SEATED.

WARNING: WHEN COMPRESSING THE SPRING, TIGHTEN THE SPECIAL-TOOL ADJUSTMENT BOLTS EVENLY.





10. Compress spring.
- Fit and align special tools 204-179 diametrically opposite on spring.
- Evenly tighten special tool tensioning bolts to compress spring.





11. Remove shock absorber to wishbone mounting nut and bolt.





12. Remove nuts securing shock absorber/spring upper mounting to body.





13. Using special tools 204-179-1, secure upper mounting to spring.





14. Using a jack, retract shock absorber through wishbone aperture.





15. Position a bolt through the spring coils and shock absorber lower-bush, to temporarily locate shock absorber.

16. Partially lower jack for access to top of shock absorber.





17. Adaptive damping system only:
- Disconnect shock absorber harness connector by pressing lugs down and pulling connector up.

18. Lower and remove jack.

19. Remove shock absorber/spring assembly from vehicle and place assembly on work bench.

20. With assistance, manually compress shock absorber and withdraw bolt from spring coils.





21. Remove shock absorber from upper mounting.
- Use a spanner on shock absorber shaft flats to prevent rotation (wrench in end socket on adaptive damping).
- Slacken and remove shock absorber upper retaining nut.
- Withdraw shock absorber from spring.





22. Remove special tools 204-179-1 securing upper mounting to spring.





23. For installation purposes, mark position of tool arms on spring.

CAUTION: The type and number of packers fitted to rear springs is dependent upon spring rating. Some springs are fitted without any packers. The original packer(s) must therefore be retained on removal.





24. Withdraw spring from upper mounting.
- Retain lower isolator.
- Retain spring pan upper.
- If fitted, retain packer.

WARNING: WHEN RELEASING SPRING TENSION, SLACKEN THE SPECIAL-TOOL ADJUSTMENT BOLTS EVENLY.
