Hi
Thank you for your replies.
The mileage is 86000. No there is no noise when turned hard right when standing or at low speed, get it up around 30-40 and turn hard right and it will vary from nothing to a harsh grinding. I usually do short runs so I need to take it on a long one to see if it gets worse the more its used.
I will check the gaiter on the others side, I assume its ok as it passed the MOT. An interesting thought that it should be the other side that makes the noise on full lock, the noise seems to be coming from the right though.
The tyres are the correct size and there are no mud flaps on mine. Its not a tyre rubbing sound, it sounds like something metal rubbing on the brake disk. My first thought was the brake dust cover as it sounds exactly like that, however when I took the wheel off and checked it all it was fine. The cover has seen better days but there is plenty of room between it and the brake disk, I could see nothing out of place.
I tried driving around in circles in an open space and at first nothing then it began, as I drove away it grinding and stopped once straight. At normal driving its either not there or very slight, I thought it was clearing and that it was some rust maybe on the joint. The car has done very little mileage in the last year and I wondered if it has been sat with a ripped gaiter then it might have rusted and with use go away. However while taking a roundabout the other day it let rip again and quite load, even the wife heard it so that says something lol.
A tricky one
