2. Inspect and Replace Suspension Components

Inspect: Check all suspension components visually for cracks or wear.
Replace: If any components are damaged:
- Remove the wheel for access.
- Use a socket set to remove the bolts securing the damaged component.
- Install the new component and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs).
- Reattach the wheel and lower the vehicle.

3. Examine and Repair Exhaust System

Inspect: Look for holes or loose parts in the exhaust system.
Repair: If issues are found:
- Remove any damaged sections using a pipe cutter.
- Install new exhaust pipe sections using clamps, ensuring a secure fit.
- Replace any broken hangers with new ones.

4. Check and Replace Engine Mounts

Inspect: Check engine mounts for cracks or excessive movement.
Replace: If necessary:
- Raise the engine slightly using a jack to relieve tension on the mounts.
- Remove the bolts securing the engine mounts with a socket set.
- Install new mounts and torque bolts to specifications.
- Lower the engine back into place.
