FYI If you were looking to update your spindles to help reduce your steering effort you should have gotten 08 or newer spindles. Okay, first you have to set your camber, jack the sled up off the ground with the skis removed and put a 5/8" bar that is 45" long through the spindle on one side so that it hangs below the other spindle and measure from the top of the casting that sticks out for the bushings. Not sure what the specs are for the RMK. Then you need to make sure the skis are straight and aligned with the track and then set them so that they are toed out 1/8"-3/8". Make sure everything is tight and you should be done.
