Disconnect the negative battery terminal if necessary for safety.

2. Inspect and Replace Worn Components

Sway Bar Links and Bushings
1. Locate the sway bar and its links connecting to the lower control arms.
2. Use a socket set to remove the bolts securing the sway bar links.
3. Inspect the bushings for cracking or deterioration; replace if necessary.
4. Install new sway bar links and bushings, tightening to the manufacturer’s specifications (typically around 30-40 ft-lbs).
Struts
1. Remove the wheel for better access to the strut assembly.
2. Unbolt the strut from the lower control arm and the top mount under the hood.
3. Inspect for any oil leaks or physical damage; replace struts if found faulty.
4. Install new struts, ensuring all bolts are torqued to specification.
Wheel Bearings
1. Remove the wheel and brake components to access the hub.
2. Check for play in the wheel bearing by rocking the hub; replace if necessary.
3. Install a new wheel bearing, ensuring proper greasing and torque specifications are followed.

3. Reassemble and Test

Reinstall all components in reverse order of removal.
Ensure all bolts are torqued to specifications.
Reconnect the negative battery terminal.
Reinstall the wheel and lower the vehicle.
