On most sleds you can pull them back through a track window. Check the curve on the front of the skid for wear, they wear out there first.

If you look at your new slide and Eye ball it with a wrench, either a 1/2 or a 12mm would be as thin as you would want to go! Now slide the wrench along the hyfax and see if it slips on, Replace them! Or wait till fall and do it before it gets cold?
Look at the very front of the hifax and compare the thickenss (of the tip) to the thickness in the middle, around where you sit (where the most weight is over the slides). If there is a significant thickness difference, then you need new hifaxes. Some are easy to take off, some are more difficult. Best thing I found is to get the end out of a window in the track, drill a hole in it, tie a sturdy peice of cord through the hole and put a heavy bar on the end of the cord and yank on it until the slide comes out. Also, have someone holding the track and moving it back and forth to allow the hifax to slide out.
most of my sleds have a line in the hyfax to give a limit indicator if you will , its about
a quarter of an inch off the bottom, you hit the line , they are wore out !
the ole boy i work with puts any where between 1200- 1500 miles a year , wears out a set every year, has a lot to do with where you ride , how you ride , how many bogie wheels on you rails will help or not on hyfax wear !
