My womans 93 yj is being dumb. It runs great for a while and then clutch will start letting out "goofy" (her words). She puts a little clutch fluid in and its fine. The level never gets very low, maybe half and inch in between fill ups. I figured it was a leaking slave cylinder. Am I right? If so, how complicated is it to replace? I am pretty mechanical, so I figure I can do it. A mechanic said that 93 was a strange year for Jeep and they did a lot of things different, he wanted over a grand to fix it. Thanks in advance, lane.
