Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello, my name is Bobby. Thank you for the question. If the brakes are fine then you either have a loose or worn suspension part, a worn engine mount, or a cv axle that is failing. Most of the time it is from a worn engine mount. Do you hear any noise when accelerating or just when braking?
If it is only happening when braking then it is either the cv axle or there is still something loose on the front suspension that is shifting when braking.
