Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench, jack stands.
Lift the vehicle using a jack and secure it with jack stands.
Inspect all visible suspension components, including struts, control arms, and sway bar links.
Tighten any loose bolts to the manufacturer’s torque specifications.

3. Replace Worn Components

If any components are identified as worn or damaged, proceed with replacement:
- Struts/Shocks: Remove the wheel, unbolt the strut assembly from the top mount and knuckle, and replace with new units.
- Sway Bar Links: Remove the nuts from the sway bar link and replace with new links.
- Control Arm Bushings: If needed, remove the control arm and press out the old bushings using a bushing tool, then install new bushings.

4. Reassemble and Lower Vehicle

Reinstall all removed components in reverse order, ensuring all bolts are torqued to specifications.
Reattach the wheel and lower the vehicle from the jack stands.
