Are you supposed to grease or oil your clutch? I have an 88 Laredo and I went to get some coffee this morning. As I was pulling away my clutch stuck to the floor. I use my foot to pull up on the side of it and it popped up and killed the jeep. First time its done this and didn't do it the rest of the way home. Made me look like a fool. I herd some Cherokees have hydraulic cylinders but do the old renix have them too? Any info is helpful. Thank you
