Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Remove any components obstructing access to the engine mounts (e.g., air intake duct).
2. Support the engine using a suitable engine support or jack with a wooden block.
3. Unbolt the old engine mounts using a socket set and remove them.
4. Install the new engine mounts, tightening bolts to the manufacturer’s specified torque value (refer to service manual).
5. Reattach any components that were removed for access.

3. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick or fill plug.
2. Remove the dipstick and check the fluid level, adding fluid if necessary.
3. If fluid is contaminated, drain the transmission fluid using a drain pan.
4. Replace with the manufacturer-recommended transmission fluid, ensuring the fluid is at the correct level.
5. Recheck for leaks after filling.

4. Tire Inspection and Replacement

Sub-steps:
1. Inspect all four tires for uneven wear and proper inflation (recommended PSI can be found on the driver’s door jamb).
2. If any tires are worn unevenly or damaged, replace them with new tires.
3. Perform a wheel alignment if necessary to ensure proper handling and tire wear.
