Right got a bit of a strange one here developed this morning just been out and had it jacked up no visible signs. When underload its fine no noise at all, pulls as it should all the way through the gears. But as soon as I lift I get a continues knock. I have no play in the wheels when jacked up, tested both sides. Also noise stops when I lift the handbrake to get it to bite so makes me believe it not the diff. Pads and disc's don't look to bad and drove fine Yesterday.
So any ideas
Rear diff ? But I'd have put money on it being all the time. but not had a rear diff go on me before.
Rear struts need replacing ?
