Clutch Pedal Vibration At Idle / In Neutral Goes Away with slightest


Recommended Posts

2001 C4 Cab 60K miles, Got new clutch at dealer 6 mos/6 k ago. Intermittently about 10% of the time that am at a stop light in neutral, foot off clutch and the clutch pedal pulsates/vibrates, and it makes a low frequency ticking sound (about 3 times a second tick-tick-tick sound behind the dash) that moves with RPMs. The weird thing is that the slightest depression of the clutch makes the sound go away, but you can feel the pulsating still. I have read other threads and am stumped. I don't know much but am thinking it can't be throw out bearing because that is not loaded in neutral at idle foot off clutch right? and would not dealer have replace throwout bearing any way? dealer said flywheel looked fine 6k ago. I have seen similar problem on another thread fixed by replacing clutch master but cant bring myself to do it without seeing a way a stinkin clutch master could vibrate on its own. I think its just conducting shakes from the clutch - seem more likely? Any idea what this is? guidance appreciated as I am afraid to let it fester. Other than this shaking , the clutch performance is fine.

You have not mentioned the number of miles the car has done, it is possible that the guiding sleeve where the trust bearing slides on, is worn. This component is often "forgot" to replace.

had clutch (and IMS) replaced at 54k miles, and I am now at 60k miles. I don't know much, but isn't the throwout bearing (same as thrust I assume) and the sleeve it sits on not doing anything when the clutch is out? or maybe I see what you mean and as long as the shaft is spinning that the bearing sits on it would vibrate if there was play in the sleeve load or no load. If that is it is that just an annoyance to live with until I see a performance degradation? many thanks

RFM is referring to the sleeve the thrust bearing slides on at the front of the gear box. They sometimes get worn and need replacing, but even if they are in good shape, should be lubricated during reassembly. Often over looked.............
