I have not had this problem with the other sm465's in my other trucks...I probably have over 200,000 miles on the one in my 74 K20 and never a problem,,,Bilt4me, they are not hard to rebuild, just a pain in the a#s to pull and put back in....especially mine with the transfer case behind it....don't be afraid to rebuild it yourself if you have a press.....
