Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Remove the front wheels using a socket set.
- Inspect the CV boots for tears or leaks.
- Check for any play in the CV joints by moving them side to side.
Replace if necessary:
- Remove the axle nut using a torque wrench.
- Disconnect the lower control arm from the knuckle for better access.
- Slide the CV axle out of the transmission and replace with a new one.
- Reassemble in reverse order, ensuring to torque the axle nut to manufacturer specifications.

3. Examine Suspension Components

Inspect Control Arms and Bushings:
- Check for cracks or excessive wear.
- Replace any damaged control arms or bushings.
Reassembly:
- Make sure to torque control arm bolts to the specified torque values.

4. Exhaust System Inspection

Check exhaust components:
- Inspect for loose hangers, clamps, or rusted sections.
- Tighten or replace components as necessary.
