Tools Required: Wrench set, exhaust pipe cutter, jack stands.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the exhaust system for cracks, holes, or loose connections.
3. Tighten any loose clamps or fittings.
4. If damage is found, cut out the damaged section and replace it with a new section of exhaust pipe.
5. Reattach any hangers and secure all connections.

3. Check Drivetrain Components

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Inspect the CV joints for any signs of wear or tearing in the rubber boot.
2. Check the driveshaft for any play or damage.
3. If wear is evident, replace the affected CV joint or driveshaft.
4. Ensure all bolts are torqued to manufacturer specifications.

4. Replace Engine and Transmission Mounts (if necessary)

Tools Required: Socket set, torque wrench, pry bar.
Sub-steps:
1. Remove any components obstructing access to engine and transmission mounts.
2. Unbolt the mounts from the engine and subframe.
3. Use a pry bar to gently lift the engine/transmission and remove the old mounts.
