Creaking Clutch GQ Patrol

You were right Nav, the creaking was coming from the ball pivot that the fork rests upon, not the slave cylinder plunger or the actual pedal pivot itself. I managed to lubricate the pivot by pulling back the fork which reveals the ball pivot and then applied a dollop of grease to the end of a screwdriver which I carefully used to apply it with. (If anyone attempts to perform this fix, I'd advise that you make sure that the spring which sits inside the fork arm is fitted properly into it's retainer slots before replacing the rubber boot.) I then smeared a generous bead of silicone around the new rubber boot (Genuine Nissan part $17.50) and installed it in place. I was unable however, to get any grease onto the two contact points on the thrust bearing no matter how hard I tried as it proved to be just too difficult for me to reach. Anyway, once I finished the repair and had re-installed the slave cylinder I jumped into the drivers seat and began pumping the clutch pedal. Not only had that annoying creaking completely gone, but I also think the clutch is about 30% easier to depress than it was before! Thanks very much for your assistance in this matter. Thank you too for your advice Shaker, I have a Nissan sedan which also has a slight creaking sound coming from the clutch and I know for a fact that it isn't coming from the ball pivot or slave cylinder either. When I get a chance I'll take a look at the pedal pivot bracket as you suggested.
