Cass or anybody have input? Some people, not many, are complaining of 'clicking' during coasting conditions, apparently due to the pinion gears shifting around in their "pockets" (that's an Eaton term) in the case. They recommend NOT using synthetic lube, presumably to avoid this issue. My concern is whether or not the units made specifically for our 8 3/4's make this noise? Anybody?
