Hi Buick BOOK Guru's Need the book knowledge help on this one. Seems we have a weird axle seal and bearing system we can not find listed in any book etc.???? The vehicle is a 1970 Buick 9 3/8" rear with OILED BEARINGS that measure 3.150 like a ford 9" Here are some pictures. Does anyone have any other part numbers that this axle bearing and seal can be other than A10 ALL other bearings in all the books are SEALED bearings for this rear and year etc. ???????? HELP?
