VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Doping on Outside of rear Brake Drum

I have a small doping leak on the outside of my rear brake drum on my 1931 Chevy Coach(6 cyl). Can that be caused by anything other than an axle bearing seal leak? Is it wise to replace the bearings and seals if I must go in there? Are special tools needed?
Thanks.

Sounds like you need to replace the inner and outer rear axle seals along with the torque tube bushing seal in the front of the torque tube. If the torque tube bushing seal is defective that will allow the oil from the transmission to run down the torque tube and overfill the rear axle. When the rear axle housing is overfull, then the oil will run out through the rear axle seals and saturate the rear brake linings with oil.

I see in the Filling Station catalog that they offer a tool to take out the torque tube bushing and they also mention that the bushing can be used as an addition without taking out the old bushing. Any thoughts on that?

My 31 has 45k original miles. Should I replace the Axle and third member bearings while in there?

Any idea how much doping will be needed to change the transmission and third member doping?

I have a Chevy repair manual but these topics are not addressed.
Thanks.

I did that. The additional support makes sense. However, later I had to undo the u-joint to remove the transmission and clutch and there wasn't enough room to fully back the rear part of the u-joint all the way.

A 1931 is a different story than a 1934 and up that has a front and rear bushing and the rear bearing can be left in place.
With the one busing it will be necessary to remove the original (not pressed in) and installl new.
