BMW X3 With Severe Front Knocking Sound Whilst Driving
This client brought their BMW X3 in to GP Motor Works because the car had a severe knocking sound coming from the front of the car.
We traced the fault to excessive play in the front wheel bearing. However, further inspection revealed the knock was actually coming from the steering rack. This type of noise (knock) appears loudest when travelling on roads with lots of corrugations. In most instances, this issue requires the steering rack be replaced.
Steering Rack Repair
A new steering rack kit was ordered and installed. The clearances on the bushes were set up. The right hand wheel bearing was also replaced.
We also advised the client to replace the tyres which were badly worn and to get wheel alignment done.
