Update:
Okie bushing removed and replaced. Still experiencing a rotational tapping/rubbing upon deceleration and/or coasting with clutch pedal in.
It sounds like it’s coming from right below the floor board but I suppose with the enclosed driveline the noise can travel.
Any ideas on here before I open the rear differential cover and have a look?
