4. Reinstall the exhaust system and tighten all connections to the manufacturer's torque specifications.

3. Replace Worn Engine Mounts

Sub-steps:
1. Use a socket set to remove the bolts securing the engine mount to the engine and chassis.
2. Carefully lift the engine slightly using a jack to relieve pressure on the mounts.
3. Replace the old engine mounts with new ones and secure them according to specifications.
4. Lower the engine back into position and re-torque the bolts.

4. Inspect and Repair Drivetrain Components

Sub-steps:
1. Check the transmission fluid level and condition; replace if needed.
2. Inspect the differential for any signs of leaks or wear; replace fluid if necessary.
3. If any issues are detected, consult a professional for potential repairs or replacements.
