There is several threads on this, you can find them by using the search function. Here is just one RECOIL ROPE
They are a piece of cake to do nothing hard about it. Do the following and you won't have any problems. Remove the can should be 5 springs, then there are 3-10mm bolts I believe may be 11mm not sure, but anyway take them out of the recoil housing and remove that from the sled and set it to the side, once you have the recoil loose from the housing pull the rope all the way out and grip the white plastic wheel inside the recoil tight DO NOT LET GO.... now you can cut your recoil handle off ( the rope ) remember DO NO LET GO.... after doing this you can remove the old rope and insert the new in the recoil once you have a knot in the rope feed it back through your dash and put your handle back on then its safe to let go slowly and it will rewind its self to the proper tension and you can move it around to put the recoil back on just watch the wiring harness so you do not pinch the wires. I have done this many of time and its easy once you do it. Sometimes if you do not have a extra set of hands to hold the recoil I have already used the jaw vise grips with just enough force to hold it in place. If you have to pull the recoil housing and take the rope out, then you will have to put new tension on the spring by twisting everything counter clockwise (I think) and then install a new rope while holding everything. Its not as bad as it sounds. What sled are you doing this to the one in your profile? If so the ZL isn't hard. I've done mine before. But it will make it easier if theres two people once you have the tension back on it or you can use a larger pair of pliers to hold the cone in place just don't crack it. It may take you a coulp of times to get the tension right but its not bad. Hope this helps.
