Use a jack to support the engine/transmission assembly.
Remove any components obstructing access to the mounts.
Unbolt the damaged mounts from the frame and the engine/transmission.
Install the new mounts by reversing the removal process and torque to factory specifications.

3. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, tire balancer, jack
Check tire pressure and inflate to recommended levels if necessary.
Inspect tires for uneven wear; replace if damaged or excessively worn.
Use a tire balancer to ensure tires are correctly balanced; re-balance if needed.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar
Visually inspect the driveshaft for any signs of damage or looseness.
Check CV joints for torn boots or excessive play; replace if necessary.
Reinstall any components removed during the inspection.

5. Fuel System Check

Tools Required: Fuel pressure gauge, basic hand tools
Inspect fuel injectors for clogs; clean or replace as necessary.
Check the fuel filter and replace if clogged or dirty.
Ensure proper fuel pressure is maintained during engine operation.
