light axle
They usually have the heavy one in stock but not the light. The heavy axle is what we call a BB (big bearing) found in later years 76-77 maybe? Your 69 is the smaller unless somebody changed it. A quick look at the rear center section is a good quick indicator also.
Ya pull the brake drum and you can get the 4 bolts off with a hole found in the axle shaft end. Then put your drum back on backwards and thread on two lug nuts a few turns and using the drum as a slide hammer pull the axle shaft out along with the bearing. Then inside the tube youll see the seal. I put a new seal in last week and damaged it because it was some super thin chinese junk for $12. Mine leaked right away again. JBG has them seals for $4! I rocomend renting a seal and race driver from wherever you get the seal.
When i pulled mine apart i did notice some goop between the axle housing, backing plate, and the retaining plate. I regooped upon assembly, but not sure if its necessary. I dont see what its doing on there. I think there were 2 gaskets from the factory?
