Is it possible to remove the axel shafts to get to the brakes without removing c-clips in the differential? I have a 1987 C-20 chevy suburban(3/4 ton, 13" drum). I would like to know if how to get the drums off w/o having to break the diff. cover(if possible). Does the shaft just come out? It fees like there is something holding it in there. I would appreciate any help anyone can offer. Thanks.
