Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repairs.

2. Change Engine Oil

Sub-steps:
1. Place an oil drain pan under the oil pan.
2. Remove the oil drain plug using a socket wrench and allow the old oil to drain completely.
3. Replace the drain plug and torque it to the manufacturer's specification (typically around 20 ft-lbs).
4. Remove the old oil filter using an oil filter wrench. Lubricate the rubber gasket on the new filter with a bit of new oil and install it.
5. Fill the engine with the correct type of oil (consult owner's manual for specifications).

3. Inspect and Tighten Components

Sub-steps:
1. Visually inspect engine mounts for wear or damage.
2. Use a torque wrench to tighten any loose bolts on the engine and transmission mounts to manufacturer specifications.
3. Check the condition of the drive belts; if cracked or worn, replace them.

4. Test Drive and Monitor

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and allow it to idle for a few minutes.
3. Take the vehicle for a test drive to ensure that the knocking noise is resolved.
4. Monitor for any new noises or warning lights during the drive.
