Clutch pedal noise

My clutch pedal when I step on it makes a godawful noise!

The mounting location for the cable at the firewall is in perfect shape, I pulled the pedal assembly apart and greased the complete shaft that the pedal pivots on, I removed the cable and thoroughly oiled it, and I have tried mounting the cable holder at different degrees in relation to the pedal thinking it may be set wrong (although this should not make a difference except in pedal travel). But as soon as any tension is applied to the cable it starts making noises as if something is rubbing really hard. The slower you move the pedal in the more noise it makes and you can feel the grabbing noise in the pedal. If you stomp the pedal very quickly you will barely hear the rubbing\grinding noise (the noise is still there only the rate at which it is generated has changed).

By the sound of it I expected to find my cable cutting into the housing or firewall but as mentioned earlier these look perfect?

Any thoughts?

Are you sure that it's the pedal and not the clutch itself??

I know that conjures some unpleasant thoughts, but - other than adjusting it for proper tension (do a search for clutch and adjustment at Ack's FAQ) - it sounds like you have pretty much checked everything in the linkage...

I just came back in after toying with it some more, I really oiled the cable alot, remounted it to the firewall and instead of using the pedal I used a screwdriver to pull on the cable as the pedal would and again it made the sound, so now it seems as if it is definitely not the pedal but the cable that is making the noise. I can barely pull the cable when reaching up there but as soon as tension is applied to the cable I start to hear the noise. So for the fun of it I go ahead and remount everything to the pedal, step on it and now my noise is worse than ever /ubbthreads/images/graemlins/frown.gif What should I really be using to lubricate the cable instead of WD40? I thought the WD would be better than nothing though?

In my cases, that's usually been the sign to replace the cable. I've never known precicely WHY it makes that groaning noise, but putting in a new OEM cable always solves the problem. Possibly some of the strands have worn out and newly exposed strands (without grease on them) are now rubbing against the casing. Or maybe there's a small troll trying to sleep in the bellhousing, and he is yelling at you to stop trying to wake him up.

Now let's talk about WD-40.

WD40 is NOT a lubricant but a Water Displacer.

Sure, it has short term lubricating properties as it is made of oil... however it's more of a false effect than a lubricant. The WD40 gets in there and breaks up existing lube and redistributes it, and sometimes it lands where you want it. This then quickly has a negative effect as the relocated lube will continue to travel, probably away from the needed place and then rapid unlubed wear will begin.

I think WD40 should ONLY be used for trying to break stuck things loose (but even then PB Blaster is better.) As its name states, the main use of the product is water displacement with the thin oily residue left behind to choke surface rust for a short period of time. Once that residue starts to break down, back comes the water to it's proper spot under the oil.

What should you use in its place? I like that white lithium grease in the red spray can. It comes out watery-thin, but gels up pretty quickly to the consistency of soft butter.

For futher information on lubricant I suggest the following site:

Good luck. We're all counting on you.

OK ho ho hold the phone here.

It seems that lubrication is the problem.

Any way to fit a zerky fiting on there, or is it not worth the effort?
