Hello! Can anyone chime in about how difficult it is to change out a rear axle seal on a bus? Our 1992 Bluebird TC2000 is leaking from the left rear wheel. The shop quoted us $400 including an inner and outer bearing. I am wondering if it is a job I can do myself. I am fairly good mechanically... but don't know if it's something that requires special tools, etc. I have never worked on anything as big as the bus
