Steps
- Raise the rear and remove the wheel
Loosen the lug nuts while the car is on the ground. Lift the rear at an approved point, support it on jack stands, and remove the wheel to expose the shock mounts.
- Remove the old shock
Support the suspension as needed, then remove the upper shock nuts and lower mounting fastener. Guide the shock out of its mounts without damaging the brake hose or nearby wiring.
- Install the replacement shock
Position the new shock and start its upper fasteners. Raise the shock slightly with a jack if needed to align the lower mounting holes, then install the lower fastener and tighten all mounts to the vehicle specification.
- Reinstall the wheel and inspect
Mount the wheel and hand-start the lug nuts. Lower the car and tighten the lugs in a star pattern to specification, then inspect the shock and nearby lines for leaks, contact, or incorrect routing.
Check your vehicle’s repair manual for exact specifications and fit.
