BW 3.27 rear end. axle seal help
anyone ever do an axle seal on these? these rear ends are different from others because there is no C clip. you gotta take out the 4 bolts at the end of the axle to remove it. also the seal is mated to the axle bearing. will i need to replace the bearing when i change the seal?

Yeah different than the 10 bolt. It has a pressed on collar, the bearing and finally the seal. All three need to be pressed off to replace the seal. I would plan on replacing the bearings when you replace the seal. I've done a few, and the bearing always gets damaged. A large hydraulic press is needed, a machine shop probably can do it for a fair price.
