Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Disconnect the battery to prevent electrical issues.
Gather necessary tools including a socket set, torque wrench, and inspection light.

2. Inspect and Replace Engine Oil

Sub-steps:
1. Locate the oil drain plug under the vehicle and place a drain pan beneath it.
2. Remove the drain plug using a socket wrench and drain the old oil completely.
3. Replace the drain plug and torque it to manufacturer specifications (typically 20-25 ft-lbs).
4. Remove the oil filter using an oil filter wrench and install a new oil filter.
5. Refill the engine with the appropriate grade of oil (typically 0W-20 for RAV4) through the oil filler cap.

3. Inspect and Tighten Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Inspect all suspension components including struts, control arms, and sway bar links for any signs of wear or damage.
3. Tighten any loose bolts to the manufacturer’s torque specifications.
4. Replace any worn or damaged components as necessary.

4. Inspect Exhaust and Heat Shields

Sub-steps:
1. Start the engine and listen for knocking noises while inspecting the exhaust system.
2. Check for loose heat shields or exhaust brackets and tighten them as needed.
3. If any heat shields are damaged, replace them with new parts.

5. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals and ensure they are tight.
2. Start the engine and take the vehicle for a test drive to ensure the knocking noise has been resolved.
