Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.

2. Inspect and Replace Suspension Components

Sway Bar Links:
1. Remove the nuts securing the sway bar links using a socket set.
2. Replace with new sway bar links if they are worn or damaged.
3. Torque the nuts to manufacturer specifications (usually around 15-20 lb-ft).
Shocks/Struts:
1. Remove the bolts securing the strut to the steering knuckle.
2. Disconnect the upper strut mount by removing the nuts.
3. Install the new struts in reverse order of removal; torque to specifications (typically 30-40 lb-ft).
Control Arm Bushings:
1. Remove the bolts securing the control arms.
2. Replace worn bushings with new ones, ensuring proper orientation.
3. Reinstall and torque bolts according to manufacturer specifications (usually 40-50 lb-ft).

3. Verification of Installation

Ensure all fasteners are properly torqued.
Reassemble any removed components and lower the vehicle.
