Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect Suspension Components

Sub-step 1: Remove the wheel on the suspected side (front or rear) using a socket set.
Sub-step 2: Inspect the struts or shocks for any leaks or damage.
Sub-step 3: Check the condition of control arm bushings and ball joints. Replace any components that show signs of wear.

4. Replace Worn Components

Sub-step 1: If shocks or struts are worn, remove the upper and lower mounting bolts using a socket set.
Sub-step 2: Install the new shock or strut, ensuring it is aligned correctly.
Sub-step 3: Torque the mounting bolts to the manufacturer’s specifications (typically around 30-50 lb-ft).

5. Reassemble and Lower Vehicle

Replace the wheel and tighten the lug nuts in a star pattern to the recommended torque (usually around 76 lb-ft).
Lower the vehicle off the jack stands and remove the jack.
