Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts on the affected wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Suspension Components

Check the struts for leaks or physical damage.
Inspect the bushings for wear, cracking, or separation.
Look at the sway bar links for looseness or damage.

4. Replace Worn Components

For struts:
- Remove the strut assembly by disconnecting it from the lower control arm and top mount.
- Replace with new struts, ensuring to torque bolts to manufacturer specifications (typically around 40-50 Nm for strut mounting).
For bushings:
- Use a bushing press or appropriate tools to remove old bushings.
- Install new bushings, applying lubricant as needed, and ensure they are properly seated.
For sway bar links:
- Remove the old sway bar link from the sway bar and control arm.
- Install the new sway bar link, torquing to specifications (usually around 20-30 Nm).

5. Reassemble and Lower Vehicle

Reinstall the wheel, hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to specifications (typically 100-120 Nm).
