Project Double-stock HDi - On hold pending removal of thumb from arse

[Poodle]

To sort the binding rear brakes i picked up a pair of calipers from the scrappy and refurbed them myself with new sliders etc. However, plans for MOT'ing this in the near future have temporarily ground to a halt, mainly because i can't work out what's causing the appalling noise when i drive it forwards. Turns out the exhaust is nowhere near the subframe, so i don't think it's that, the noise seems to be coming from the osf hub area (at least it does when it's up on axle stands, hard to pinpoint the source when i'm driving it), maybe driveshaft or wheel bearing...? Can't feel any play and the cv boots look good, so nothing obvious to suggest a problem. And it doesn't add up to me either, why only in forward gears and not reverse...?

Now i'm just waiting for some good weather/daylight outside of working hours so i can fit the brakes and work out what the fook is going on with this noise.
