Hi was giving front axle refurb on 844xl and noticed a bit of movement in the bearings of these. Got the bearing and gears off but there's stupid clip that doesn't have any means to remove bar breaking all my small screwdrivers. I also saw some pics of replacement roller bearings on these that don't have outer shell when pricing up. Is it supposed to be gear and bearing replaced together. Pic must be of tidier side as one with wear has more grazed and burnt oil look. Thanks.
