Took my car to to the dealership on multiple occasions to find a knocking sound in my car.
Ball joints, engine mounts, suspension overhauled and no results. Still a bloody knock. Had byron service my car one day and also heard the knock in the car. You know a guy that knows cars when he finds a can of V in a small void in the floor under a car seat and says his had it before. Great service and knowledge and exceptionally priced. Highly recommended
