Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during the repair.

2. Inspect and Replace Worn Components

Inspect Control Arms and Bushings:
- Remove the wheel to access the suspension components.
- Examine the control arms and bushings for cracks or excessive wear.
- If damaged, proceed to replace the control arms.
Replace Control Arms:
1. Remove the bolts securing the control arm to the chassis and the steering knuckle using a socket set.
2. Detach the control arm from the vehicle.
3. Install the new control arm and torque the bolts to manufacturer specifications (typically around 60-70 ft-lbs, check the service manual for exact values).
Inspect and Replace Strut Mounts:
- Check the strut mounts for any signs of wear or looseness.
- If worn, remove the strut assembly and replace the strut mount.
Reassemble:
1. Reattach the wheel and lower the vehicle.
2. Reconnect the battery and perform a final inspection of all fastening components.
