Clutch push rod rattle.

If you adjust the push rod yourself use a 12mm for the jam nut and a 13mm for one you are jamming against. Loosen the 12mm and spin the rod to make it longer. You want a little bit of play, like 2mm or so. Don’t make the rod so tight that it doesn’t move a little. Too tight will potentially cause your clutch not to fully engage and slip.

 

I will give this a go. After my drive home the engagement still didn't feel 100% right a little high still but amazing compared to what it was.

If i had to give my thoughts the clutch master failed. It didn't have the spring it has now. It felt slow and lazy. Who knows.

 

The other clutch adjustment is the pedal height. Maybe that is what feels high. I left mine at the factory setting. If you do adjust pedal height you will also need to adjust the push rod.

 

*update*

Still an issue. Truck drove like... hmm like a dog box super hard shifts off and on clutch peddle it was so bad. ( I should note i could hear the sound time to time also) so I adjusted the push rod back so I could actually drive the darn thing and its just as bad as before.

Looking at jeeps and full size trucks now. Really not happy with my tacoma now. I already had a lemon buying experience and I am not looking forward to another.

 

I found this on another fourm. Possibly a bad instal from the manufacturer? But I had the issue later on so wouldn't the problem be immediate?

The clutch disc is a steel plate, covered with a frictional material that is sandwiched between the flywheel and the pressure plate. The center of the disc is the hub, which fits the spines of the transmission input shaft. When the clutch is engaged, the disc is "squeezed" between the flywheel and pressure plate, and power from the engine is transmitted by the disc's hub to the input shaft of the transmission.

A pressure plate is a metal spring-loaded friction surface that is bolted to the flywheel. It has a metal cover, heavy release springs, a metal pressure surface, and a thrust ring or fingers for the release bearing. The thrust ring or fingers release the clamping force of the springs when the clutch is disengaged.

When the clutch pedal is depressed, the "Throw-out bearing" pushes the pressure plate's release fingers. The pressure plate pulls away from the clutch disc, disengaging the clutch, thus interrupting power flow. When the clutch pedal is released and the clutch is fully engaged, the release bearing is normally stationary and does not rotate with the pressure plate.

Clutch operation is accomplished with a hydraulic pressure system.

On a hydraulically operated clutch, a master cylinder is directly operated by the clutch pedal assembly. A slave cylinder at the transmission is connected to the master cylinder by high-pressure tubing. The slave cylinder pushes an operating lever on the release bearing.

Your problem:
If you have vibrations comming from rotating clutch parts (slipping friction material, bad release bearing etc), these vibrations could be tranferred backwards in the hydraulic system via the slave cylinder to the master cylinder and could be felt as slight vibrations in the clutch pedal.¨

Misalignment
Misalignment occurs when the clutch assembly is not correctly aligned with the flywheel. This causes the clutch to engage unevenly, placing an unbalanced load on the clutch and flywheel surfaces. The usual result is chattering, pulsating and vibration of the clutch pedal.


Broken Diaphragm Spring
The diaphragm spring controls the amount of pressure applied to the pressure plate and clutch disc, and seats them against the flywheel. If the diaphragm spring is damaged or broken, this causes the clutch plate to engage the flywheel unevenly when applied or released, which in turn causes vibration and pulsation of the clutch pedal.


Warped Clutch Disc
The clutch disc is the portion of the clutch assembly that actually connects the flywheel to the transmission when you engage the clutch. It's made of a material similar to that of brake pads, and operates on the same principle of friction. In order to operate properly, all the contact surfaces of the clutch assembly must be smooth and flat, including the clutch disc. If the clutch disc becomes warped due to wear or overheating, it will not engage smoothly with the flywheel and pressure plate. This results in chattering, vibration and clutch pedal pulsation.


Improper Throw-Out Bearing Installation
The throw-out bearing is the part of the clutch assembly that engages and disengages the clutch. When you press the clutch pedal, the throw-out bearing moves forward and pushes on the pressure plate fingers, which releases the spring pressure and pushes the pressure plate against the clutch disc.

An improperly installed throw-out bearing will not contact the pressure plate fingers evenly or smoothly. This causes the pressure plate to push against the clutch disc unevenly, leading to vibration and pulsation of the clutch pedal.""

 

Good points but I had this issue before and after I installed the stage 2 clutch and new ToB

 

And I should say the creak and vibration don’t really annoy me. I’ve always had a Tacoma. They are noisy as hell, ever heard your truck off road from outside the vehicle? I remember on that one guys YouTube channel that does recoveries he has a buddy that he brings that has a SAS 2nd gen Tacoma and everyone in the comments saying holy shit is somethings breaking and he said nah it’s just a Toyota.

 

I dont mind creaks and small rattles. But I can hear this over the stereo at max volume. Who knows what will end up happening. If I had to guess the dealership on Friday is going to tell me its my fault or just adjust the push rod all the way out again and call it "fixed". I might mention a buy back but dealerships shut down and what to fight once you say anything like that.

 

Truck is going back in Monday. The clutch pedal is practically to the floor at this point. Its starting to slip as well.

Corporate toyota is involved and I am trying to have it worked out. Toyota said the truck will get fixed no matter what no cost to me. I was told the transmission will be pulled. I believe the clutch springs failed or the pressure plate.

 

Any update?

 

I'm having this same issue. I have 2017 with the stock clutch with a tad under 30,000 miles. Here's what my push rod is doing. This doesn't appear right and I get the same vibration rattling. I'm taking my truck in for routine service in the next few weeks so I'll have to tell them about this. I hope they don't try to charge me... there's no way this push rod should come loose with so few miles.

Mi

mine does that too. 2017 stock clutch. I guess it’s normal.

 

That's a big bummer... I hope this isn't just the norm! I'll have to talk to my dealer... luckily I have a good relationship with their service department so we'll see what they have to say.

 

Mine does this too but not quite as bad, also the pedal squeaks like crazy. The dealership says that they will replace the clutch pedal assembly and master cylinder under warranty, I’m currently waiting for the parts to arrive.

 

Probably something I need to ask the dealer but do you know if the extended Toyota Care warranty covers this?

 

I'm not sure, I am still under the original warranty.

 

Update:

Getting all the parts in took longer than I expected, but Toyota replaced everything under warranty and the clutch petal no longer makes any noise.
