Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Repair Suspension Components

Tools Required: Jack, jack stands, socket set, torque wrench.
Raise the vehicle with a jack and secure it with jack stands.
Visually inspect the struts and springs for any signs of damage or unusual wear.
Check the bushings for any cracks or excessive play.
If any components are found damaged, replace them as follows:
- Remove the damaged strut or spring using the socket set.
- Install the new part and torque to manufacturer specifications.
- Reassemble and lower the vehicle.

3. Examine the Exhaust System

Tools Required: Wrench set, exhaust hanger removal tool (if necessary).
Inspect the exhaust system for loose connections, rust, or damage.
Tighten any loose bolts or replace damaged hangers.
If there are holes in the exhaust, use exhaust repair tape or replace the damaged section.

4. Check CV Joints and Axles

Tools Required: Socket set, pry bar.
Inspect the CV boots for tears or grease leakage.
Check the CV joints for any play; if they are worn, replace them:
- Remove the wheel and hub assembly.
- Use a pry bar to detach the axle from the transmission.
- Install the new CV joint and reassemble in reverse order.

5. Inspect Wheel Bearings

Tools Required: Bearing puller, socket set.
Raise the vehicle and remove the wheel.
Check the wheel bearing for excessive play by wiggling the wheel.
If the bearing is faulty, remove it using a bearing puller and replace it with a new one.
