Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery for safety.

2. Engine and Transmission Mount Replacement

Locate the engine and transmission mounts.
Remove any components obstructing access to the mounts (if necessary).
Unbolt and remove the damaged mounts using a socket set.
Install new mounts by positioning them correctly and hand-tightening the bolts.
Torque the bolts to manufacturer specifications (refer to the vehicle’s service manual for specific torque values).

3. Tire Inspection and Replacement

Inspect all tires for wear patterns and ensure they are properly inflated.
If uneven wear is present, rotate or replace affected tires as necessary.
Balance tires if required using a tire balancing machine.

4. Drive Shaft and CV Joint Inspection

Lift the vehicle and secure it with jack stands.
Inspect the drive shaft and CV joints for any play or damage.
If damage is found, remove the affected components and replace them with new ones following the vehicle service manual.

5. Transmission Fluid Change

Locate the transmission fluid dipstick or drain plug.
Drain the old transmission fluid into a suitable container.
Replace the transmission filter (if applicable).
Refill with new transmission fluid according to the manufacturer’s specifications, ensuring the correct type is used.
