how to diagnose the knocking noise in my Toyota RAV4 XA40 (2013-2018)

Solution

1. Preparation

• Tools Required: OBD-II scanner, mechanic's stethoscope, jack and jack stands, socket set, torque wrench.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery if necessary for safety.

2. Address Engine Issues

• Remove the drain plug using a socket set and allow old oil to drain completely.
• Replace the oil filter with a new one.
• Reinstall the drain plug and torque to manufacturer specifications.
• Fill the engine with the correct type and amount of new engine oil.

b. Tighten Loose Components

• Inspect the engine mounts and tighten any loose bolts.
• Check and fasten any loose accessories (e.g., alternator, power steering pump).

3. Repair Suspension Issues

a. Inspect and Replace Worn Components

• Lift the vehicle using a jack and secure it with jack stands.
• Inspect struts/shocks for leaks or damage; replace if necessary.
• Check control arms and bushings for wear; replace as needed.
• Torque all fasteners to manufacturer specifications during reassembly.
