How conerned should I be about throwout bearing squeak?

I have determined that I have the notorious throwout bearing squeak on my 2006 w/ 113,000 miles (previous owner had Toyota replace the clutch and throwout bearing at 75k). When the truck is idling in neutral with the clutch released, it squeaks. The noise goes away when the clutch is pressed.

I know that some have suggested a clutch slave cylinder rebuild, but from what I've read it doesn't sound like it always works.

What I can't figure out after all of my reading through various threads is whether or not this squeak is something to be concerned about. Is anyone having to replace their clutch and throwout bearing with greater frequency as a result of this problem? Or is it just a matter of dealing with the annoyance of the noise?

I want this truck to be reliable and last a long time without issues, so I want to figure this out. What is everyone else doing?

 

I just deal with it. Had one clutch replaced to get rid of the noise and it came back within 10k miles. Its a common Tacoma issue but one that is mostly just annoying...technically the throwout bearing can fail and that could be a very expensive repair, but you really only hear about that occurring on cars that put out a lot more power than our trucks.

I've never heard of it happening on a Tacoma...not saying it hasn't but everyone I've heard of with the issue either lives with it and is fine or upgrades to the URD hydro kit that supposedly fixes the issue

 

I saw some discussion recently that the URD hyrdo kit was NLA. I have made no effort to confirm this though... If so, that currently does not leave many options other than replacing with another OEM bearing and continue to use the transmission's aluminum quill, or the stainless quill sleeve with the modified OEM bearing kit by PD&M.

@joelmiller285 I believe the spring upgrade in the slave cylinder may be more effective if the mod is implemented relatively early -- such as when the chirping noise begins -- rather than to wait a long time for the wear pattern in the T/O bearing raceway to become established. If that is the case, yours seems to have gone about 38k mi. since the last bearing and if this were mine I would certainly try hiadun's mod or the factory parts and see what happens as this would be absolutely the least costly at this point.

Since you plan on keeping the truck for a long time as stated, and if your 3rd gear grind worsens or just becomes intolerable, you might want to keep your eyes and ears open for a low mileage 6-speed from a '13-15, with the closer to '15 being preferred.

 

Mine has made a noise for the last 100,000 miles on cold mornings I going to wait until I do the clutch at 200,000 something miles.

 

I'm definitely going to try the slave cylinder upgrade. I really don't want to have to replace the transmission.... Kind of bums me out to hear about this problem. I always thought Tacomas were one of the most the most reliable vehicles on the road.

 

Tacomas are reliable...not without their quirks, but that goes for anything really. I don't think the throwout bearing chirp disqualifies them as a reliable vehicle at all.

 

This may or may not be what you need but its worth a look.

I have an update on my throwout bearing saga. Now the chirp happens all the time, not just in neutral. So if I'm driving down the road the transmission is chirping as I go. Super annoying. I did the clutch slave cylinder rebuild with the updated Toyota parts and had no luck. Should I get the clutch replaced? I don't want my transmission to grenade itself.

 

Mine started squeaking last spring, I rebuilt the slave cylinder and it went away for abou 3k miles or so and came back. It’s been chirping the last 10k miles and I’ve kinda just gotten used to it.

Is the trans gonna damage itself? Doubtful. Will it be annoying? Definitely.

 

They all do that , just turn up the radio !

Instead of upgrading the slave cylinder couldn't the clutch free play just be adjusted from inside the truck such that it always applies a small amount of force to engage the TOB since it is made to spin continuously? Does putting in a stronger spring (04313-34011) and longer push rod (31473-35060) in the SC do this differently than taking out the free play by adjusting the free play adjustment screw?

Thanks in advance.

 

That would work theoretically, but I believe it would lead to premature wear of the clutch.

My clutch chirping is getting worse. Some days I really hate this truck and want to sell it.

Where did you get the notion that the TOB is made to spin continuously? It is not. It spins only when the clutch pedal is depressed enough to move the TOB into contact with the spinning clutch pressure plate spring fingers. To have it spin continuously would cause it to fail in short order.

 

This is true, however, the transmission shaft runs through the back solid part of the release bearing (attached to the clutch fork) . If the throw-out is making noise it should only do it when engaged (assuming proper clutch adjustment). Sounds like a problem where the shaft runs through the part that is attached to the fork. I've never had a taco clutch apart, but did change two clutches myself on a '74 and a '78 Yoda, both were hydraulic systems.

 

URD stainless steel sleeve and retrofit TOB. My TOB squeek became apparent around 30k miles, changed it at 35k and coming up on 100k now... noise basically went completely away and remains that way.

 

If the TOB is making noise it needs to be replaced.

 

I bought my 08 model 4.5 years ago with 100,000 miles. It started squeaking shortly after so it was either covered up somehow by the dealership or the clutch was fairly new. I haven’t had to change anything yet clutch or TOB and I just rolled over 240,000 miles. It’s annoying but it’s not “broke” so I’m not fixing it

 

The squeak is being caused by the TOB riding with too much tension on the pressure plate. Specifically the squeak is coming from the clutch fork pivot ball bouncing up and down in the fork pivot point. Doing a slave cylinder replacement or rebuild adds more tension to the TOB.
Replace your clutch and TOB with an OEM set.

 

Not sure how good of an idea it was, but I had TO bearing squeak on my 91 Camaro so I took an oil can (the old school looking kind with a trigger than will shoot a thin stream of oil 5-10 feet if you really yeet on it) and pulled the clutch fork grommet out of the way and haphazardly spooged a couple ropes of 30-weight into the bellhousing in the general direction of my TO bearing and the squeak went away completely and hasn't come back a year or two later.
