IF your Slide used the clip on wiper seals these are about the easiest to replace. Wife and I did these together.. needed her help to hold the old seal and new seal down on the ground side by side to cut the new seal length correctly..
One 35 foot roll will easily replace the horizontal and both vertical wiper seals on a large hydraulic slide
Time to accomplish - about 30 minutes for all 3 seals and that includes a sip or two of coffee..
Two videos I made showing you how simple this job is:
