97 Tacoma cutch release bearing
 
Howdy y’all. Just need some advice. I believe the clutch release bearing on my Tacoma is making noise. On start up there is a chirping sound which goes away with the lightest touch on the clutch pedal. (It does not require me to press it in, just a small touch and the chirping stops.) it is a new clutch I installed a marlin crawler clutch about a year before this started. (I emailed their tech support, by the way, and heard nothing back just crickets.)

first, do y’all agree that this sound is likely the release bearing? Secondly, how long do y’all think I can get away with it chirping before it messes something up. Do I need to change this right away, or is it something I can just live with for awhile. Thirdly, I’ve done a few clutches in the past on other Toyotas and never had any issues, but is there anything I could have done wrong on the install? Like did I grease the shaft too much or too little?

thanks. I don’t want to mess up this truck, it’s my baby!

The application of even the slightest pressure causing the sound to go away is pretty much the textbook symptom of a bad throw-out bearing.

How long do you have? Maybe 1000 miles, maybe 100,000 miles there’s really no way to gauge it. If the sound gets worse, the bearing is getting worse.

Thanks. I have been gambling with it for a bit and hope it hasn’t done much, it hasn’t been getting worse at least. I guess I will change it out next time I get a few days off. I hated doing this one, that transmisssion plus xfer case is heavy as heck and I don’t have any fancy tools. Muscling that thing into place is a pain...

How long it till it fails completely who knows.

I have had some go years .

Just your bad luck to get a bad bearing .

Bruinpilot Aug 2, 2018 12:04 AM

It is only on start up and goes away after a couple of minutes... bad luck is my middle name...

Does the sound go away if you put your toe under the clutch pedal and pull up (just touching it)?

Don’t know about pulling up? I will give that a try and see what happens. What does that mean if it goes away with a pull on the clutch?

if the noise goes away just by touching the pedal from the bottom it may be just a vibration issue with the pedal/pivot/mount.
when you first start your engine you probably have more vibration than when it warms up.

Yes. It does quiet down when warmed up and pretty much goes away. Takes longer when it is cold outside. Will try it and see what happens when I get home Saturday.

If you tear it apart, do you have a floor jack? I mounted a wooden "platform" on my floor jack and did not have to get a transmission jack. I did have to get help lining the transmission up to go back in, from my angle looking from the floor it looked okay, but somebody else standing at a different angle said, "You're way off!" Once I adjusted it went back together easy!

Bruinpilot Aug 3, 2018 07:09 AM

I’ll try that out. Did you use two jacks, one for the tranny and one to keep the engine from sagging?

fierohink Aug 3, 2018 08:54 AM

I like to make a sling around the frame rails with ratchet straps. Then you can crank up or control going down and swing and twist it to get it lined up with the motor.

I always use two floor jacks make sure to have them aligned with the transmission I learned that the hard way years ago.

I put a ratchet strap supported by a piece of steel up in the cab allowing movement forward as needed .
