Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, mechanics stethoscope, socket set, torque wrench.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged before lifting the vehicle.

2. Remove Wheel

Loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Suspension Components

Examine the struts and shocks for any oil leaks or physical damage.
Check control arms, sway bar links, and bushings for signs of wear or separation.
Inspect the springs for cracks or deformation.

4. Replace Damaged Components

If any components are found to be damaged, replace them with OEM or quality aftermarket parts.
Follow specific torque specifications for reinstallation (refer to service manual).

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications.

6. Alignment Check

Take the vehicle to a certified alignment shop if the suspension components were replaced or adjusted.
Ensure the alignment is within specifications to prevent uneven tire wear.
