4. Remove the old shock/strut from the vehicle.
5. Compare the new shock/strut with the old one to ensure correct fit.
6. Install the new shock/strut by reversing the removal steps, tightening bolts to manufacturer specifications (usually around 20-25 ft-lbs).

3. Inspect and Replace Other Suspension Components (if necessary)

Sub-steps:
1. Check the control arms and bushings for wear and replace if damaged.
2. Inspect tie rods and ball joints for play; replace if necessary.
3. Reassemble any components removed during the inspection.

4. Alignment

Sub-steps:
1. After replacing any suspension components, take the vehicle to an alignment shop.
2. Ensure that the alignment is adjusted to the manufacturer’s specifications.
