Hello, what do I have to do to change the seals on the rear axle where the rear wheel is located? On your answer could you discribe it step by step? Ask Wolfgang
Jack up and put jack stands under rear end. Take off wheels and brake drums Take cover off back of differential---10 bolts Remove set bolt that runs through the spider gear pin---about 3 inches long and has a small hex head usually 5/16 to 7/16 inch Remove pin and square spacer block Push in on axle and remove horseshoe shaped "C" clip Pull axle out Remove seal and install new one
3600 uses a H-050 rear axle which was used on 3/4 and Chevy and GMC trucks at least into the late 1950s. I don't know where to find a maintenance manual for an early 50s Chevy truck, so I'm referencing an on-line 1957 GMC Maintenance Manual which has good coverage of the H-072, heavy duty version but mechanically the same as the H-050. I checked this on-line copy of the '57 GMC Maintenance Manual against my paper version of the 1952 GMC Maintenance Manual and they agree everywhere I have referenced below. Start reading here: 1955 - 1959 GMC Trucks Maintenance Manual - Models 100 - 500 The good stuff (rear hub and bearing replacement) is here: 1955 - 1959 GMC Trucks Maintenance Manual - Models 100 - 500 When the manual refers to a "type A,B, or C" yours is a type A (all series 150 and 250). There is a reference to section 2 for axle shaft removal. Look here 1955 - 1959 GMC Trucks Maintenance Manual - Models 100 - 500 for removal of H-072 axle which comes out the same way as your H-050.
I've find the manual: 1954 Chevrolet Truck Shop Manual I've dismantled the wheel housing. Here are some pictures: Bilder | Unterrichts- und Übungsmaterialien
