Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Visually inspect the CV joints for any cracks or grease leakage.
4. If damage is found, remove the axle nut with a socket and ratchet.
5. Detach the CV joint from the transmission and the wheel hub.
6. Replace the damaged CV joint with a new one, ensuring proper alignment.
7. Reattach the axle nut and torque it to the manufacturer specifications (typically around 130-150 ft-lbs).

3. Inspect and Repair Exhaust System

Sub-steps:
1. Inspect the exhaust system visually for loose hangers or cracks.
2. Tighten any loose clamps or brackets; replace any broken hangers.
3. If damage is found in the exhaust pipe, cut out the damaged section and replace it with a new pipe using appropriate exhaust clamps.

4. Check and Replace Suspension Components

Sub-steps:
1. Inspect the struts and bushings for wear or damage.
2. If the struts are worn, remove the strut assembly by loosening the upper and lower mounting bolts.
3. Replace with new struts and torque to manufacturer specifications.
4. Replace any damaged bushings using a bushing tool if necessary.
