Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, securing it with jack stands.
Ensure the vehicle is stable before beginning any inspection or repair.

3. Inspect and Replace Shock Absorbers/Struts

Inspection:
- Remove the wheel to gain access to the strut.
- Check for oil leakage and physical damage to the strut.
Replacement:
- Use a socket set to remove the bolts securing the strut assembly.
- Detach the strut from the lower control arm and the top mounts inside the engine bay.
- Install the new strut in reverse order, ensuring all bolts are torqued to manufacturer specifications.

4. Replace Worn Sway Bar Links/Bushings

Removal:
- Locate the sway bar and its links.
- Use a wrench to loosen and remove the nuts securing the sway bar links.
Installation:
- Install the new sway bar links and bushings, ensuring they are properly seated.
- Torque the nuts to the specified value according to manufacturer guidelines.

5. Check Wheel Bearings

Inspection:
- Spin the wheel by hand while the vehicle is lifted to check for noise or play.
Replacement (if necessary):
- Remove the wheel and brake assembly.
- Use a bearing puller to remove the faulty bearing and replace it with a new one.
- Reassemble the wheel and brake components, ensuring all fasteners are torqued properly.
