Last year I screwed up by leaving my Sx-ct drive oil screws loose and seized up my drive so this year I got a replacement sx-st drive. The problem I'am having is that the lower leg little did I know was not the original from the sx-ct so now I cannot get a seal between the lower and gear box on the oil screen so I cannot pressure test it does any one have any ideas beside replacing the lower leg I replaced the o-ring on the screen side but one on the shaft side is not required
