Jeep newcomer looking for tech/build help

Hi,
I'm new to this forum so I hope that I'm posting in the correct place. I'm sure I'll figure this whole thing out soon.
A little background on my jeep. I recently inherited the family Jeep. A 2002 Wrangler Sport with the 4.0 inline 6. The car is starting to get bad do to the lack of upkeep. The engine has around 130,000 miles on it so it's gotten a lot of use. While the may have been through it's paces I am determined to bring it back to life. It has never been used for off roading. It is strictly a road car that we've used frequently since we bought it new in 2002. The engine still runs perfectly fine. It's never given up on us and it is really the only part of the car that was taken care of.

Down to my actual question. The clutch on the car has taken a beating do to poor driving by my mother and the fact that I learned to drive stick in this car. So lot's of engine killing, clutch popping, and gear grinding. The last person to drive the car before it was given to me was my father. He mentioned that the car was making a weird noise kind of like a high pitched whine. It only does this when the clutch is engaged. I believe that it may be the fact that the clutch is still the stock clutch meaning it has taken years of torture but I'm worried that it may be something else all together.

I was wondering if I could get an opinion on what this noise might mean.
Also, if people could point me in the direction of good websites to buy parts from. More specifically I am looking for a new clutch right now. So I would appreciate clutch brand recommendations.

Thank you so much

LuK 05-065 Clutch Kit by LuK http://www.amazon.com/dp/B000CICYZ4/..._jcYptb08V5GDQ

Possibly the throw out bearing if it's doing it when the pedal is pushed. The kit above is great and highly recommended here. I have one in mine.

You can download a free factory service manual from www.jeepslimited.com

Here are some helpful videos. I made one Water Dog made the other.

what year?

What do you mean by 'clutch is engaged', often people get confused about that. If it whines when the clutch pedal is depressed (that would be the clutch DIS-engaged) then it's likely the throwout bearing.

Year is important, that'll tell people what transmissions(s) it might and what the options are.

Thank you for the quick response Majnoon I will watch the videos and check out the clutch.

mhicander it is a 2002 Wrangler Sport. When I said "clutch is engaged" I meant the pedal is not depressed. So the car is in gear and moving. It makes the whining noise while the car is in gear and moving. Then when the clutch is depressed and the car is sitting still or even if you are just rolling then the noise goes away.

Then it is probably not the clutch. Does it shift okay? Is the noise coming from directly under you, or could it be coming from front or back? Can you hear it when it is just idling in neutral with the clutch up?

I am actually not home now and haven't driven the car in a while. I am a student so I don't use the car much. I called my father (the one who told me about the noise) and apparently I was wrong.
According to him the noise happens when the clutch is pushed in. So pedal pushed down, clutch disengaged, the noise shows up. So it most likely is the throw out bearing then.

Also, may I ask what exactly the throw out bearing does and why it is causing this noise?

Sorry for any inconvenience I should have made sure my facts were straight before posting.

The release fork pushes it into the fingers that release the clutch. When it pushes them it releases The clutch from the fly wheel and as it's holding those fingers in spins with the engine. Which is why it whines when you hold it in.

Take a look at the videos, then if you need it, I've also got a step by step write up in PDF format. If you want that, shoot me a pm.
