Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Suspension Components

Inspect Shocks/Struts:
- Remove the wheel to access the strut assembly.
- Check for signs of oil leakage or physical damage.
Replace if necessary:
- Unbolt the top mount of the strut from the engine bay.
- Remove the lower mounting bolts from the steering knuckle.
- Replace with new shocks or struts, ensuring to torque all bolts to manufacturer specifications (usually around 30-50 ft-lbs).

3. Examine and Replace Bushings

Inspect Control Arm and Sway Bar Bushings:
- Look for cracks or excessive wear.
Replace if necessary:
- Remove the control arm or sway bar as needed (refer to manufacturer specs for bolt sizes and torque values).
- Press or pull out the old bushings and install new ones, ensuring they are seated correctly.

4. Wheel Alignment and Balancing

After replacing any suspension components, take the vehicle to a professional alignment shop.
Ensure all specifications are met for camber, caster, and toe.
