I've had knackered bearings before, but this one's a winner for me. As for driving back from Germany, I have put at least 2.5K miles on the car since the noise started. lol
There's a lot of play in it. Surely it's held onto the bottom arm by four bolts, and nothing else? if it fails catastrophically, then it would just separate anyway?
It's not an issue though. It won't be moving until I replace the bearing.
Love that street sign in front of the 'driveway' btw! Did they get billed for cutting down the original sign?
