1937 Buick Roadmaster rear axel seal question

[37_Roadmaster_C]

Hello All,

I need some input from anyone who has worked on the rear axel of a 37 Buick Roadmaster. I purchased a set of seals from an old Buick supplier which were listed as being for a 37 series 80 & 90. I have now pulled the axels and have run into a problem. The seals I bought were a leather lip seal and a felt disc/washer. The seals in the car are both leather lip seals. The shop manual for this car is of little help as it conflicts... in one section it states that the rear bearings are lubricated with oil from the differential, and in another section it states that they are greased. My car appears to be greased as it uses lip seals on both sides of the bearing. Any help, input or thoughts would be apperciated.

Just to clarify, I am refering to the outer bearing area of the axel. I am rebuilding the brakes and don't want to take the risk of an oil/grease leak dammaging the new brakes. The car has not been on the road since 1952 so I am just being extra fussy with my rebuild.

Thanks All,

Robin
