What is this sound? (video)

So this sound started recently and it's getting worse. It starts after my truck warms up for a few minutes, then theres this chirping sound that only goes away when i press my clutch in all the way. I originally thought TOB, but some are saying its something in the transmission since I have to press the clutch all the way in for it to go away. I recorded this video today. The harsh sound right before the chirping goes away is when I push the clutch just enough to feel it (an inch or so), then when I push it in the rest of the way it disappears. So what are your thoughts?

bump

 

Sounds like a spring in the pressure plate rubbing. Clutch in my c230 mb sounded the same way before it exploded....

 

It's not in the transmission. When you push the clutch in, the transmission is disengaged.

I agree about the pressure plate springs rubbing.

 

My experience with this noise is more like it is a release bearing, or the clutch fork. The clutch for is an easy fix and you can search on this forum to find several fixes. I would look at that first.

 

Well if its disengaged when I press in the clutch wouldnt that explain why the sounds there until I press the clutch?? That means that sounds only there when my transmission is engaged

 

Its the TOB on the pilot shaft. You need the TSK from URD, comes with a stainless steel sleeve and enlarged TOB.

You will need to drop the trans, put the sleeve on and reinstall the trans. About a days work with the right tools.

 

I am pretty sure from the sound and your description that it's the TOB sliding on the pressure plate spring fingers. It will eventually grind all the way through them. For now, don't rest your foot on the clutch pedal, and push hard and quick to let the bearing do its job and not grind the spring down. You need a new clutch and TOB, and have the flywheel turned if you can.

 

I have a manual, I had noise just like the OP, the pilot shaft in these manual trans trucks is aluminum, and the TOB is steel. With constant use, the TOB scores the pilot shaft and creates that squeak. The reason it quits when you push the clutch all the way in is because that area of the pilot shaft is not scored as the TOB does not hardly ever operate at the end of the pilot shaft.

I used the TSK sold by URD and this has fixed my problem for over 2 years now.

 

I removed my 6 speed due to this noise exactly!!.... i had 85k miles so obviously i replaced the clutch at the same time. anyway it was the release bearing. It was very rough to turn, gritty and noisy compared to the new one. after the new clutch kit noise was gone. good luck.

 

also.. my noise followed your clutch position description to the T, the only reason i think it goes away when all the way down is the squeek is only audible during light engagement of the bearing but once pressed all the way too much pressure is on the bearing for it to squeal.. i had a stethoscope on the trans while the clutch pedal was fully pressed and the same noise was present just very muffled.

 

This makes sense, too. But, if you are going to drop the tranny and have over 60K miles, might as well replace the clutch and bearings at the same time just in case. Aisin kit with all the parts you need are $345 at RockAuto.

 

Hmm so sounds like a TOB after all. Thanks for the help guys. I was planning on upgrading my clutch n flywheel anyways, guess ill just do it sooner and put off getting bumpers for now. So i would need the urd kit, clutch and flywheel, and where should I get the bearings from? Is aftermarket worse than oem?

 

Are you talking about the TOB?

 

Like I said, RockAuto has an Aisin kit that has everything except the flywheel. But if you are doing a flywheel, are you planning on going with a stronger clutch, or ?

I would do what Kodiak and the other poster said as well.

 

yes

so that kit comes with a clutch as well? I would like to get the stage 3 or 3+ clutch/flywheel package from urd.

 

The TOB comes with the Trans Sleeve Kit from URD. Since you're putting a sleeve on there, they will be sending a bigger beefier TOB.

I think that stage 3 is a bit much for our trucks unless you plan on racing it.

 

So then all i should get is urd kit and clutch/flywheel? Or am I missing something still? What do you mean by too much? Like stiffer and harder to shift??

 

This is the TSK kit, it comes with everything: The TOB, the Sleeve, an Allen wrench, lube and instructions.

The stage 3 kit is a competition race clutch, extremely stiff, not something you'd want for everyday driving.

 

With that URD kit, you would still need the clutch disk and pressure plate. Most will come as a kit, so you'd have an extra TOB. If you really want to do the flywheel and upgraded clutch, URD sells a combo. I would stick to Stage II.
