i've just been trying to grease my props but i can't get any grease into two of the u j's. i've removed, cleaned and tested the nipples and grease goes through fine but when i screw them back in and try to grease the joint the grease just spews out around the nozzle of the grease gun with no sign of any entering the joint. i replaced the nozzle of my grease gun to see if a better fit would help but made no difference, no probs on front uj or prop sleeves just the two joints on the transfer box.
any suggestions greatly apreiciated.
