3. Check and Repair Drivetrain

Inspect CV Joints and Axles:
- Remove the wheel to access the CV joints.
- Check for torn boots or excessive play in the joints.
Replace if Necessary:
- If damaged, remove the axle nut and disconnect the CV joint from the hub.
- Install a new CV axle or joint and reassemble, ensuring proper torque on the axle nut.

4. Examine and Tighten Exhaust System

Inspect Exhaust Components:
- Check for loose clamps or damaged hangers along the exhaust path.
