It's not really a rear end....instead it's the gear drive on a new rotary mower (BCS tractor attachment)....but this thing is muy noisey right out of the box and by all accounts that's just the way it is.
Seems like somewhere in the dim past I heard of people mixing something or other into the differential lube to quiet a rear end that was on the way out....on a car that was for sale....
Anybody know of something that'll do the job, but not compromise the gears?
