Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if performing electrical work.

2. Inspect and Replace Shock Absorbers/Struts

Tools Required: Socket set, torque wrench, jack stands, wheel chocks
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the shock absorbers.
Inspect the shock absorbers for leaks or physical damage.
If replacement is necessary:
- Remove the bolts securing the top and bottom of the shock absorber.
- Install the new shock absorber in reverse order, tightening bolts to manufacturer specifications (typically 50-70 Nm for lower bolts).

3. Sway Bar Link and Bushing Replacement

Tools Required: Wrench set, torque wrench
Locate the sway bar links and bushings.
Remove the bolts securing the sway bar link to the sway bar and lower control arm.
Replace worn links with new ones and torque to manufacturer specifications (usually around 30 Nm).
Replace bushings if they show signs of wear or damage.

4. Control Arm Bushing Inspection and Replacement

Tools Required: Socket set, bushing removal tool
Inspect control arm bushings for any signs of cracking or excessive play.
If replacement is necessary:
- Remove the control arm from the vehicle, noting bolt positions.
- Use a bushing removal tool to extract old bushings and install new ones.
- Reinstall the control arm and torque bolts to manufacturer specifications.

5. Tire Inspection and Adjustment

Check tire pressure with a tire gauge and inflate to recommended levels.
Inspect tire tread for uneven wear patterns, indicating alignment issues.
Rotate or replace tires if there are significant wear differences.
