I have a 03 Renegade (MXZ) that is now a 151" and I need to change out the hifaxes (not sure if that is spelt correctly). When I have done it in the past I have always had the suspension out so it was easier. But this time around I have no need to take suspension out for anything. I know there is a way to get them out but not too sure. I know I need to pull the cap off the front of the suspension that holds the hifax in. But how do I go about getting the piece to slide back? Do I use the openings in the track to gain access. Sorry if this is a dumb question. Just want to do it correct the 1st time. Thanks.
