Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Suspension Components

Lift the vehicle using a jack and secure it on jack stands.
Remove the front wheels using a socket set.
Inspect the struts and shocks for leaks or damage.
If damaged, replace struts/shocks:
- Remove the top bolts and bottom mount bolts.
- Install new struts/shocks and torque bolts to manufacturer specifications (usually around 50-70 ft-lbs).
Reinstall the wheels and lower the vehicle.

3. Check and Repair Exhaust System

Inspect the exhaust system from the manifold to the tailpipe.
Tighten any loose bolts or clamps.
If any components are damaged, replace them:
- Cut out damaged sections if necessary and install a new section of pipe using a pipe cutter.
- Use exhaust clamps to secure the new section.
Ensure all hangers are in place and not degrading.

4. Inspect and Replace CV Joints/Axles

Inspect the CV boots for tears or leaks.
If damaged, replace the CV joint or axle:
- Remove the wheel and brake components.
- Disconnect the axle from the hub and transmission.
- Replace with a new axle and torque bolts to manufacturer specifications (usually around 50-80 ft-lbs).
Reassemble the brake and wheel components.
