why does my Toyota RAV4 XA40 (2013-2018) make a grinding noise when I accelerate

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure with wheel chocks.
• Disconnect the battery to prevent any electrical issues.

2. Inspect and Change Transmission Fluid

• Tools Required: Socket set, transmission fluid pump, fluid catch pan.
• Sub-steps:
  1. Locate the transmission fluid dipstick or fill plug.
  2. If low, drain the old fluid into a catch pan and replace with fresh transmission fluid as specified in the owner's manual.
  3. Check for contamination; if the fluid is burnt or metallic, further inspection of the transmission may be necessary.

3. Inspect CV Joints and Axles

• Tools Required: Jack and jack stands, socket set, pry bar.
• Sub-steps:
  1. Raise the vehicle and secure it on jack stands.
  2. Inspect the CV boots for tears or grease leakage.
  3. Check the CV joints for play by grasping the axle and moving it in and out.
  4. Replace any damaged CV joints or axle assemblies as necessary.

4. Wheel Bearing Inspection

• Tools Required: Socket set, torque wrench.
• Sub-steps:
  1. Remove the wheel and brake caliper to access the hub assembly.
  2. Check for any play in the wheel bearing by rocking the hub.
  3. If play is detected, replace the wheel bearing and hub assembly.
  4. Reassemble the wheel and caliper, ensuring proper torque specifications are followed.

5. Brake Component Inspection

• Tools Required: Socket set, brake cleaner, wire brush.
• Sub-steps:
  1. Inspect the brake pads and rotors for wear.
  2. Ensure that the brake caliper is not sticking; clean and lubricate the caliper slides if necessary.
  3. Replace any worn brake components to ensure they are not causing a grinding noise.
