Hi Wolfgang
Is this on the 1953 3600 in your signature? If so, look here: http://chevy.oldcarmanualproject.com/shop/1948_51truck/51ctsm0410.htm The first few pages have the procedure for removing the axle shafts, hubs, bearings and seals and replacing them. Here in the US the seals are readily available since that same axle design was used for 20+ years in 3/4-ton and 1-ton trucks. Good luck.
