MG Midget and Sprite Technical - whining/grinding??

'73 midget
Strange whining/grinding noise started.
Trying to diagnose is not easy as it wont do it all the time.
Seems to be on deceleration, in gear.
Can feel it through my feet & hear a grinding noise.
Seems to only be in gear, but not certain. Pretty sure not brakes, although it is a "moving" sound, ie, a whirring, not a constand sound.
odd
any ideas on what to check?
Suspecting prop shaft.
pretty sure that its not diff as that is fairly new.

Could be e.g. exhaust touching as engine shifts to over-run.

If propshaft, you'll be getting increasing vibration, esp at speed...

I had the same problem on mine, and found it was the backplates rubbing on the disks, after weeks of looking, it took 2 minutes with a hammer and lever to sort that. Also make sure the front number plate is away from the body, as I found the wind caused it to rattle against the grp bonnet and make a similar noise that took ages to identify.
Hope it'd nothing worse

check the tranny oil level....may have lost a rear tranny oil seal

prop
Pro P

its been suggested to me this could be loose or worn gearbox mounts...
whats your feeling on this guys?

Easy to check, since the diff mounts bolt on the x-member (2 off) and onto the transmission tunnel, under the carpet - 2 per side IIRC.

Check also your track-rod ends haev clearance with wheel-rim...
