Solution

1. Preparation

Gather all necessary tools and replacement parts.
Ensure the vehicle is parked on a level surface and engaged in gear or with the parking brake applied.

2. Raise the Vehicle

Use a jack to lift the front end of the vehicle and secure it on jack stands.
Tools Required: Floor jack, jack stands.

3. Inspect Suspension Components

Visually inspect the control arms, bushings, and ball joints for wear.
Replace any damaged or worn components.
Tools Required: Socket set, torque wrench.

4. Check the CV Joints and Axles

Remove the wheel on the left side for better access.
Inspect the CV joint boots for tears or leakage; replace if necessary.
Tools Required: Axle nut socket, pry bar.

5. Replace Worn Components

If any components such as bushings or control arms are found to be defective, proceed with replacement.
For control arms:
- Remove the bolts securing the control arm to the chassis and the subframe.
- Install the new control arm and torque the bolts to manufacturer specifications (usually around 75-85 ft-lbs).
Tools Required: Torque wrench.

6. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle from the jack stands.
Ensure all nuts and bolts are properly tightened.
