Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Disconnect the battery if working with electronic suspension components.

2. Inspect and Replace Suspension Components

Inspect Components:
- Use a jack and jack stands to lift the vehicle.
- Inspect struts and shocks for leaks or damage.
- Check control arms and bushings for wear.
Replace as Necessary:
- If any components are damaged, remove the old parts:
  - Remove the wheel to access the suspension.
  - Use a socket set to unbolt struts and control arms.
- Install new parts:
  - Align the new strut/shock with the mounting points and secure using the specified torque (typically 15-25 ft-lbs for bolts).
  - Replace bushings if worn.

3. Wheel Alignment

After replacing any suspension components, perform a wheel alignment:
- Adjust camber, caster, and toe settings according to manufacturer specifications.
- Verify alignment with an alignment machine.

4. Inspect and Balance Tires

Check tire condition and balance:
- Inspect tires for uneven wear patterns.
- If necessary, replace tires or have them balanced at a tire shop.
