This document outlines the diagnosis and repair of a rotational squeak and clunking noise emanating from the front end of a 2012 Toyota Landcruiser Prado (KDJ150R). The noise was most noticeable under load, during acceleration, or when driving uphill.
Problem
A rotational squeak, occurring approximately twice per tire rotation, was present, accompanied by a loud clunk upon initial acceleration and smaller clunks under continued acceleration. The squeak was initially suspected to be related to brakes or drivetrain components.
Solution
The mechanic diagnosed and resolved the issue by:
- Replacing the broken front left drive shaft. This eliminated the clunking noise.
- Correcting the brake backing plate position to prevent rubbing against the rotor. This eliminated the squeaking noise.
Relevant Parts
