I'm such a dumbass! I put the wheel back on today after tightening the handbrake, put the car back on the drive 'properly' and the arch clearances were the same
My drive has a slight slope but I didnt think it would have such a drastic affect on the suspension. I'v had the car in the same position plenty of times before and never noticed it. So now that's that sorted I just have a knocking noise to solve.
A while ago I had a knocking when braking, is this what you had? Only saying because I got all new disks and pads and this solved it. My knocking noise occurs whenever the car is moving. I thought it could be a siezed caliper but there was no sign of over heating from the wheels. Thanks
