Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool before starting work.

2. Inspect and Replace Worn Suspension Components

Inspect Components:
- Examine control arms and bushings for cracks or deterioration.
- Use a pry bar to check for play in the bushings.
Remove Components:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheel to access the suspension components.
Replace Worn Parts:
- If any components are worn, replace them with OEM or quality aftermarket parts.
- For sway bar links, remove the bolts and replace with new ones, ensuring they are torqued to manufacturer specifications (typically around 30-50 ft-lbs).

3. Strut/Shock Replacement

Removal:
- Detach the strut from the top mount and lower control arm.
- Remove the strut assembly from the vehicle.
Replace with New Struts:
- Install new struts in reverse order of removal, ensuring proper torque on bolts (usually 15-20 ft-lbs for top mount).
Reassembly:
- Reattach the wheel and lower the vehicle.
