I had a wheel bearing noise a couple of months ago and when i had it replaced the stub axel had to be filled down slightly so the new one would fit.
I was told if the noise starterd again i would need a new stub axel.
I have started getting a wheel bearing noise again but i cannot tell if it is that wheel again or if it is a different wheel.
Can anyone help?
