Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Struts/Shocks

Tools Required: Socket set, torque wrench, spring compressor (if needed)
If the shocks/struts are found to be defective:
1. Remove the wheel on the affected side.
2. Disconnect the brake line bracket from the strut.
3. Remove the bolts securing the strut to the steering knuckle.
4. Remove the top strut mount bolts from the engine bay or under the hood.
5. Carefully remove the strut assembly from the vehicle.
6. If using a spring compressor, compress the spring and remove it from the strut.
7. Install the new strut or shock absorber and reverse the steps to reassemble.

3. Replace Sway Bar Links and Bushings

Tools Required: Wrench set, socket set
If sway bar links are worn:
1. Locate the sway bar links connected to the sway bar and control arms.
2. Remove the nuts securing the links using the appropriate socket.
3. Replace with new sway bar links and tighten to manufacturer’s specifications.
4. Inspect and replace bushings if they show signs of wear.

4. Check Control Arms and Bushings

Tools Required: Socket set, pry bar
If control arms are damaged:
1. Remove the wheel on the affected side.
2. Disconnect any components attached to the control arm (e.g., brake lines, sway bar).
3. Remove the bolts securing the control arm to the chassis and the steering knuckle.
4. Inspect the bushings; if they are worn or cracked, replace them.
5. Install the new control arm and torque all bolts to specifications.
