lately my clutch has been making a loud kind of rubbing noise while getting off in first gear and sometimes shifting into second. once or twice the truck has died out while sitting still in the school parking lot (yes i had the clutch all the way in) it seems like I'm gonna need a knew clutch but I'm not sure since my friends jeep has 200,000 miles on his clutch. the truck itself has 110,000 miles on it and i thought clutches were supposed to last longer than that but if anyone has had this problem before let me know what it is and if i can fix it myself

 

Did the truck lurch forward when engine die?

Your symptoms don't sound like clutch disc being worn out, in any case.
Thin disc(worn out) means clutch slips when foot is off the pedal, i.e. RPMs go up but truck doesn't accelerate at the same rate, clutch is slipping
Yours sounds more like Slave or Master is losing fluid, check reservoir.
Noise could be throw out bearing on slave.


How long a clutch disc lasts depends on a few things.
Main one is driving habits, if you use the clutch pedal as a foot rest then 100k miles would be about right.
If you "feather" the clutch, upshifting or downshifting, because you are "a really good clutch driver"(your not) then clutch will wear out faster.

If you are a new owner then previous driver could have practiced the above.
Clutch disc only wears when it is between IN and OUT, so don't keep it between, foot is off the pedal or pedal is on the floor only two position it should be put in.
Brakes are cheaper and easier to change, use them to slow down, not the clutch, lol.

But yes, 200-250k is about normal for clutch disc

Slaves can go out at anytime, shouldn't but they can

 

Slave cylinder notoriously blows and can make a squeaking sound when on/off the clutch

 

well i took it in to the mechanic today and he said it was air in the master cylinder. but driving it home i really didn't notice a difference than when i took it on trails two days ago. I'm going to look into the Slave cylinder and maybe that will be it. i down shift a lot but down usually rest foot on the pedal. so i don't think its the pad

 

A bad slave cylinder will leak and you should be able to see the fluid leaking from the bell housing.

Your symptoms can come from a bad clutch master cylinder. It can leak internally without showing any signs of fluid on the outside. My master cylinder failed while still under warranty and the first one they installed was also bad. Fortunately, they realized this before I came to pick it up.

Also, bleeding a master cylinder is not easy to do. The angle of it traps air. However, from what you have described, I would bet on a bad master cylinder.

 

Just FYI, you should only use the clutch with engine and drive shaft at different RPMs when starting off.
When moving you should match engine and driveline RPMs as close as possible to avoid wear and tear on clutch disc.
So if down shifting give the engine some gas to get RPMs up to match driveline, i.e. do not use clutch disc to bring engine RPMs up.

And never rest your foot on the clutch pedal, unless you have added a BIG *** spring to the pedal that can support the weight of your leg and foot.

Brakes are easy to change and not that expensive, clutches are another story, so if you want to use engine as a brake then do it right, or just use the brakes

 

yeah the mechanic i took it into said exactly that. is there anyway to prevent it though?
