Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues while working.

2. Remove Shock Absorbers

Tools Required: Socket set, wrench set, jack, jack stands.
Using a jack, raise the vehicle and secure it with jack stands.
Remove the wheel on the affected corner for access.
Disconnect the upper and lower mounting bolts of the shock absorber using a socket wrench.
Carefully remove the shock absorber from its mounting location.

3. Inspect and Replace

Tools Required: Torque wrench, new shock absorbers.
Inspect the old shock absorber for signs of wear or leaks.
Install the new shock absorber by placing it in the correct mounting position.
Torque the mounting bolts to the manufacturer’s specifications (usually around 30-40 lb-ft, but verify with your service manual).
Reinstall the wheel and lower the vehicle.

4. Alignment Check

After replacing the shock absorbers, take the vehicle to a certified alignment shop.
Ensure the alignment is adjusted to manufacturer specifications to prevent further uneven tire wear and handling issues.
