1999 dodge dakota clutch cylinder replace it. still have no clutch. its very soft or spongy we have to push the truck for it to start. we have replace the clutch cylinder twice. and still same problem. do you have to bleed it? its my mom truck. could it be throw out bearing bad? or pin behind the clutch behind the firewall.

Did you replace just the slave cylinder or the whole hydraulic assembly, if you just replaced the slave cylinder you have to bleed it since you opened the system up.
