94 YJ, having some trouble with the clutch. This is my first wrangler ever owned,, and just not sure about allot of things. How do the clutch’s work on these? Is it hydraulic? I guess the best explanation would to call it sticky!!! It’s starting to get really hard to engage. Just in the beginning of it though. Once you push hard enough,, and goes through?? Doesn’t do this every time,,, just every once in awhile??
