After refitting my old diff/gearbox on the new 360 it now 'ticks'. It can be replicated by jacking up the wheels and turning them both, (with an assistant), with a light tick every rotation. Above 20mph its barely audiable from the drivers seat but it sounds quite harsh from the back of the car at 70mph. Any idea what might be wrong?
The oil level was abit low in the diff, after topping up the sound seemed to have quietened down a tiny bit.
