Strange Clutch Pedal Action
Bought this Jeep in Jan. PO put 5,400 miles on a complete frame off resto including the V8, Advance Adapters bellhousing, clutch, external slave kit, and new AX-15. I have put 1,000 miles on it since then with no clutch problems.
Friday while driving around town the clutch pedal suddenly developed a 'hard spot' in its downward travel just as it got into the release point. Push through that spot and the pedal suddenly goes back to normal effort the rest of the way to the floor. It feels like something going 'over center' if you know what I mean.
Consensus on another forum was that I needed a new master. Changed that and thoroughly bled the system (actually changed it 3 times). Problem went away for about the first 20 miles of driving then started to come back gradually until its now as bad as before.
One symptom that I'll try to describe is that when pushing the pedal slowly through the 'hard spot' there is a loud 'creaking' sound from under the floor like an old castle door. You can actually feel the vibration as it creaks. After pushing through the hard spot the noise and feeling go away for the remainder of the pedal travel and clutch disengagement. If you push the pedal at normal speed the noise isn't evident, just the feeling of going over center. I am working alone so I haven't been able to get under the Jeep to pinpoint the location of the noise although it seems as if it's coming from the center over the clutch area.
Through all of this the clutch works perfectly fine with nice progressive takeup and release, no chatter or slipping. Even though it works fine I feel that this is the signal of some kind of problem that should be fixed.
Any ideas on where to look?
