Doing my usual winter messing around on the RT and decided to Lube the splines on the drive shaft. Upon separating the final drive from the shaft I discovered a fair amount of water in the housing. The shaft and u-joint was covered with surface rust and the splines were rusty and no grease on them at all? I assume the boot on the housing was not snapped securing and allowed water to enter. Has anyone had this problem?
Is there anything I can use to clean the surface rust off the shaft and u-joints without hurting the bearings or seals? Suggestions?
