Clutch Replacement - 93 Toyota PickUp (2 Wheel Drive)

Yes, it's true, and yes it sounds logical.

The throw out bearing will make noise when you apply -- depress -- the clutch pedal.

You might be getting in over your head, but you said that you have done this sort of thing before, so you should be okay.

Under what conditions does the noise occur? At idle with the clutch pedal depressed and the clutch disengaged? If so, the throw-out bearing should be checked.

If it happens with the clutch engaged, then something else is the culprit.

If you are going to replace the clutch, you might as well do the throwout bearing while you are at it, especially if you sit at stop signs with the clutch pedal depressed instead of shifting into neutral and engaging the clutch.

You should check the condition of the flywheel.

Hey Ray O.! What's the life expectancy of the pilot bushing/ bearing on the end of the crankshaft?

The pilot bearing is one more little piece that's easy to do at the same time (though they can be a bear to get the old one out of the hole). But if it starts making noise later, you have to take the whole darned thing apart again to get at it.

Take your time, and be prepared with a 'parts burner' car to run into town and get something you forgot.

Do NOT get yourself into a "Do Or Die" situation, that way leads to madness... Don't start the job with the car parked at the curb if it's a Tow Away Zone Monday through Friday - you need to do the work in a garage or on a piece of driveway that can be safely occupied for a while just in case.

If you run into unexpected problems and have to bail out of the job halfway till you locate the parts, have a plan to get to work next week. Either make advance arrangements to borrow a 'spare car' from friends or family, or pre-arrange a carpool ride, or check out the weekly rate from Rent-A-Wreck.

My humble advice is that you replace the throw out bearing and pilot bearing since you are in there anyway. It's much easier and cheaper to do these bearings with the clutch then to pull all of that crap off again later.

Now, given what you just said in your post that I am replying to, I'm not sure your throw out bearing is the source of your noise. I'm leaning to the transmission itself since the whine goes away when you use the clutch -- and change the loading on the transmission when the clutch pedal is depressed.

One thing no one mentioned is that you will need an old tranny input shaft or other device to centre up that new clutch disk while you tighten the pressure plate.
