Busy overhauling propshafts and UJ, when finally got the 2 pieces of propshaft apart there is a plastic lining between the male and female splines of propshaft, and makes it an extremely tight fit as well as stopping grease getting between the metal faces. Really what I would like to know is why is that there, when there is a grease nipple as well and how do I grease it properly when fitted as plastic covers internal grease passage. Also dont see any referance to it in the manual. any info would b a big help
