Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and safely raise it with a jack and jack stands.
Wear appropriate safety gear such as gloves and goggles.

2. Inspect and Replace Worn Components

Shocks/Struts Replacement
- Remove the wheel to access the suspension components.
- Unbolt the shocks/struts from the top mount and lower control arm using a socket set.
- Replace with new shocks/struts ensuring they match OEM specifications.
- Torque the bolts to the manufacturer’s specifications (typically 50-70 ft-lbs for lower bolts).
Control Arm and Bushing Replacement
- Remove bolts securing the control arm using a wrench.
- Inspect the bushings for cracks or wear; replace if necessary.
- Install new bushings and reattach the control arm, tightening the bolts to specified torque values.
Ball Joint Replacement
- If excessive play is found in the ball joints, remove the steering knuckle.
- Use a ball joint press to remove and replace the ball joint.
- Reassemble the steering knuckle and torque bolts to manufacturer specifications.

3. Reassemble and Lower the Vehicle

After all replacements are complete, reattach the wheels.
Lower the vehicle back to the ground and perform a final inspection of the replaced components.
