I have a 1992 Jeep Wrangler with a 2.6L 4 Cylinder with a 5 speed transmission. I bought the Wrangler used from a local dealer in my area. I have had the Jeep for about one year. During that year, I have replaced the clutch slave cylinder 3 times. I now have my 4th slave cylinder on order and I am dreading a 4th teardown and re-install. I would like to know if there's any additional factors that might be causing this problem to occur. I have flushed the hydraulic system twice now and found no signs of oil contamination. If anybody knows what's wrong or what the solution is please let me know. THANKS!
