Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Worn Suspension Components

Remove the Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Shocks/Struts
- Check for fluid leaks around the shock absorbers or struts.
- If necessary, remove the lower bolt and disconnect the shock/strut from the mount.
- Compare the old shock/strut with the new one for compatibility.
Replace Shock/Strut
- Install the new shock/strut in reverse order of removal.
- Tighten the lower bolt to manufacturer specifications (typically around 40-60 ft-lbs).
- Reinstall the wheel and torque lug nuts to the specified value (usually 100-150 ft-lbs).

3. Inspect and Replace Control Arm Bushings (if needed)

Access Control Arms
- Remove any components obstructing access to control arms, such as sway bar links.
Remove Control Arm
- Detach the control arm from the frame and lower ball joint by removing the bolts.
- Inspect the bushings for cracks or excessive wear.
Replace Bushings
- Use a bushing press to remove old bushings and install new ones.
- Reattach the control arm and torque bolts to specifications.
