I was able to get the rear wheels pulled off the car this weekend and I am glad that I did. The rear axle seal seems to have been leaking into the axle bearings and running out into the brakes. How can I tell if it ruined the axle bearings? How much play would be too much? Also, how do you get that seal all the way in the axle tube out? I don't have that special tool that is in the service manual.
