Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, wrench set, jack stands, torque wrench
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the rear wheels to access the rear shock absorbers (if applicable).
3. Disconnect the bolt at the top and bottom of each shock absorber using the socket set.
4. Remove the old shock absorber from the mounting points.
5. Install the new shock absorber, ensuring it is oriented correctly.
6. Torque the bolts to manufacturer specifications (generally around 30-40 ft-lbs, but check the service manual for exact values).
7. Repeat the process for the front shock absorbers if necessary.

3. Perform Wheel Alignment

Tools Required: Wheel alignment tool
Sub-steps:
1. After replacing the shock absorbers, lower the vehicle back onto the ground.
2. Use a wheel alignment tool to adjust the camber, caster, and toe settings according to manufacturer specifications.
3. Test drive the vehicle briefly to ensure that the steering is straight and responsive.
