Solution

1. Preparation

Tools Required: OBD-II scanner, jack stands, torque wrench, socket set, transmission fluid.
Disconnect the battery to ensure safety while working on electrical systems.

2. Engine Mount Replacement

Lift the vehicle and support it securely with jack stands.
Remove the engine cover if applicable.
Locate the engine mounts and inspect them for cracks or excessive wear.
Using a socket set, remove the bolts securing the mounts to the engine and chassis.
Replace with new engine mounts, tightening to the manufacturer's specified torque values.

3. Transmission Fluid Change

Locate the transmission fluid pan and drain plug.
Place a drain pan under the transmission and remove the drain plug to let the fluid drain completely.
Replace the drain plug and refill the transmission with the correct type of fluid as specified in the owner's manual.
Check the fluid level using the dipstick and ensure it is within the recommended range.

4. Tire and Wheel Inspection

Inspect each tire for uneven wear and check the pressure with a tire gauge.
Rotate the tires if uneven wear is detected.
Balance the wheels if necessary using a wheel balancer.

5. Suspension Component Replacement

Inspect suspension components for wear, including bushings and struts.
If any components are worn, remove them using a socket set.
Install new components, ensuring they are properly aligned and torqued to specifications.
