I wonder if this is just an aspect of the car due to the steel ring/pinion gears and shaft-drive?

Do you run with the kit shims on the outdrives to space the ring and pinion gears? The mesh seems fine to me with the kit shims.

I lightly lube the gearboxes with a SMALL amount of Associated black grease.

Any views?
Comes from the bearings for the spur moving about. Underneath the plate that holds them down, use something soft to pad them slightly. I just use double sided tape but don't take the backing off the side facing the bearing and this stops the noise.
