I have an 8 inch rear end that I took from a 78-80 Granada. Grease was leaking on the pass. side so pulled the shaft. Afterward looked into housing and found a round, approx. 1 3/4 in. diameter spring close to the seal. Figured it became dislodged from the seal upon shaft removal. Can I just use a simple seal puller and then reiinsert? I've been told that it can only be done by a shop and it has to be pressed in.
Also, would like to change rear fluid. There is no drain plug or bolt on rear cover. Can a vacuum pump be used, or does the front have to come off, or are there other options?
