Go buy some WD40 and Finishline Wet XC lube. Pull off the driveshell and blast the splines with WD40 so clean everything, then let that dry for a bit (hair dryer speeds everything up) and open a gap between the driverings and dribble in a little finishline and then spray in a little wd40 to thin the finishline even more. then put on the driveshell again and away you go. Jobs a goodun, mine hasnt skipped for about 6 months now.
