Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Shock Absorbers/Struts

Tools Required: Socket set, torque wrench
Remove the wheel using the socket set.
Unbolt the shock absorber/strut from the top and bottom mounts.
Inspect for leaks; if damaged, replace with new shock absorbers/struts.
Torque the new strut bolts to manufacturer specifications (typically around 40-50 ft-lbs).
Reinstall the wheel and lower the vehicle.

3. Replace Control Arm Bushings

Tools Required: Jack and jack stands, socket set, bushing removal tool
Raise the vehicle and secure it with jack stands.
Unbolt the control arm from the chassis and the ball joint.
Use a bushing removal tool to extract the old bushings from the control arm.
Install new bushings and reassemble the control arm, ensuring proper torque specifications are followed.

4. Replace Sway Bar Links

Tools Required: Socket set, wrench set
Locate the sway bar links connected to the sway bar and the control arm.
Remove the bolts securing the sway bar links using the socket and wrench.
Install new sway bar links and ensure they are torqued to specification.
