Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Replace Suspension Components

Remove the Wheel:
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle with a jack and secure it on jack stands.
- Remove the wheel.
Inspect the Control Arms:
- Check for any visible cracks or breaks in the control arm.
- If damaged, remove the control arm bolts with a socket set.
- Replace with a new control arm, ensuring proper torque (consult the vehicle manual for specifications).
Examine the Struts/Shocks:
- Check struts for leaks or damage.
- If necessary, remove the strut assembly using a spring compressor and replace it.

3. Check CV Joints

Visual Inspection:
- Inspect CV joint boots for tears or grease leakage.
- If damaged, replace the boot or CV joint assembly.
Remove the Axle:
- Use a socket set to remove the axle nut.
- Detach the axle from the hub and replace with a new axle if the CV joint is faulty.

4. Replace Engine/Transmission Mounts (if necessary)

Access the Mounts:
- Remove any obstructing components to access the engine and transmission mounts.
Remove Old Mounts:
- Unbolt the mounts using a socket set.
- Replace with new mounts, ensuring proper alignment and torque specifications.

5. Final Assembly

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Recheck all components for proper installation.
