Clutch related issue; One of the bearings is squealing while decelerating in 1st gear and second gear, it also makes the same noise while engaging the in reverse.

It does not make any noise while the clutch is depressed or not while sitting still at idle. ( that cancels out release bearing right?)

It also made a clicking noise while under load at low rpm's.It also made a clicking noise while engaging in 1st gear.

The clutch plate, slave cylinder, and all the bearings were replaced 100 miles ago.(OEM) I have not dumped the clutch once, or been hard on it in any way.



If its not one of the bearings . . . I know its not:

1. Trans/engine mounts
2. Oil contamination (No leaks anywhere)
3. Transmission related (new trans)
4. Engine related (new engine)
5. Fluid level issue
6. Slave cylinder (clutch still grabs like new, no slipping/chatter, pressure appropriate)


Any possible idea's will help a lot. Thanks for anything. . .

Well, if it was a bearing it'd be the throwout or pilot bearing. Since the noise happens with the clutch engaged, I'm tempted to say it's the pilot bearing.

A lot of mechanics DON'T replace it when changing out the clutch, simply because its hard to get out.

 

Sorry I should have said "engaging" . . . as it begins to grab. And your point about the pilot bearing normally being passed up. . . well, thats what happened the first time. That was my second clutch replacement in 500 miles. The 2nd and last replacement I had was done at a different shop, where they informed me thats what the 1st shop had done (left the 20 year old pilot bearing and throwout bearings in there.) He insured me he would fix it, and the pilot bearing/Throwout bearings was silenced after that second job. I'm really damn confused over all this.

To further clarify. . . While sitting at idle in neutral, I can press and depress the clutch all day long and it makes no noise whatsoever. The second I go forward in 1st gear and it has almost fully grabbed it clicks, then; The second I start to decelerate in 1st it starts squealing. If I push in the clutch; everything stops.(noise wise)

 

Alright, but if the clutch is fully engaged, and you slow down and it starts squealing, I would assume that's a lack of grease on the pilot bearing. I'm not sure, to be honest.

I recommend editing the title to "Clutch Bearing Makes Noise" or something along those lines.

 

Too late more me to edit it. . . Mods feel free.

Edit: Thanks for the advise though. I've got an extra pilot bearing and throw out bearing laying around the house here. . . I'm hoping if I take it to the previous shop they will replace it using my parts and not rape me due to the lack of miles driven since their "repair". Its been a year since they did it, but they recorded the mileage when they performed the job, and I would be surprised if there was more than 200 miles since that was done. ****. . . we'll just have to wait and see I guess.

/QUOTE]

It not only cancels out the release bearing, it also cancels out the pilot bearing. The pilot bearing is operating only when the clutch is depressed as the flywheel is spinning, but the trans shaft/clutch disc is stationary.
If no noise at idle when clutch engaged, but when in first, transmission noise, or drivetrain related eg driveshaft.

 

I agree with turbonut. It's not your pilot bearing. I suspect the front u-joint on your driveshaft.

 

Thanks. . . that makes a lot of sense. I'll have to take a look at it.
