NEW 6MT Clutch Pedal Squeak/Creak Noise Revised TSB (T-SB-0112-19)

Yep, but in reality the metal master cylinder has to be okay. Now, if there is an interface change, then I might run into a problem. As far as I can see, the pedal and the bushing would be my only concern.

That price for the pedal assembly was not what I saw online:

A bit more than $150, but fluctuation is expected.

Not to mention, the dealers are not paying list prices for this stuff.

 

I'll take a blow torch to it to simulate summer heat before i pay those prices...

 

No I'm with you for the mechanically inclined it can be done relatively on the cheap. But if its covered under warranty and there are new revised parts coming down the pipe I say why not.

 

I heard farting while you're driving really speeds up the process as well.

 

I used some silicon spray lube for mine and it's been pretty smooth.

 

I took a look at the revised parts today, have some pictures and some additional information to post up when I get a moment. Possibly an alternative option.

They were trying to do JIT at my old job and it never made any freakin' sense at all, constantly having to fly parts in along with FedEx overnight deliveries, and holding work crews over or needing weekends to catch everything back up. Would have been far less expensive, time consuming, and generally less hassle to simply keep some damn parts in the crib.

 

They do JIT at my company too. Just as useless

 

Glad this only goes to 36,000 miles...

guess I missed it by about 60,000

 

Exactly. Some of the shit made sense, some of it was a total waste, and I swear the rest of it was getting a close up look at other company's proprietary data.

 

I find it bs that those with extended warranty aren't covered for this

 

I find it bs that after 10+ years they cant make a pedal that doesn’t squeak...

 

very interested to hear anything you can offer when you get some time. i am also in the hunt for info regarding older pedal assemblies that may fit w/o big headaches. i heard of 2nd gens swapping in a FJ metal pedal assebly, but i just don't want to commit to something unless i know how the install may look more or less.

 

Interesting that they've done that, as that was one of the things I am looking into.

JIT works well for production facilities where demand can be controlled or at the very least accurately predicted. It can work well for after-sales parts distribution within reason, however predicting demand can be a much bigger challenge, especially when you want to ensure supply to the primary user (assembly line). For items like recalls and/or TSB's, there is a balance between ramping up production for the distribution network and launching the action in a timely manner. You can't just release the recall today when there are no updated parts available, but you also can't wait X months until you've built up a massive stock in all of your distribution networks and dealers. Toyota actively discourages and/or limits dealer stock for certain parts to try to prevent a couple of dealers from taking all of the stock, leaving others with nothing. Take a look at the Takata airbag recall and how many vehicles/years of production it has taken to get enough stock to replace them in most vehicles (3+ years).

In any case, that's not really what I'm here to talk about.

Here is the updated pedal and bushing. This bushing did not exist on any of the previous pedals up to 31311-04021, but it is commonly used on metal pedals where the return spring makes contact with the pedal. Also worth noting is that the TSB provides better information regarding the type of grease to be used compared to previous revisions.






And the updated master cylinder. While the TSB states that all parts must be changed together, that is only partially true, as it depends on what the truck had previously. The master cylinder clevis must match the pedal. The current master cylinder matches 31311-04020 and 31311-04021 pedals. (31420-60031 and 31420-60032 can be identified by the colour of the clevis being either zinc-coloured for the 60031 or black coloured for the 60032).


So that's what the latest TSB for the Tacoma uses, and as I was looking at the master cylinder (for which Toyota sells no components) and noticed that the pushrod boot has a part number on it that actually matches a mid-80's Land Cruiser. That got me thinking about whether other vehicles used a similar pedal setup, since Toyota decided to swap the Tacoma master cylinder out for the Land Cruiser Prado 120 design, maybe there was a pedal in another vehicle that would work in the 2005+ Tacoma.

My first guess was the Hilux, but it looks like they use a more conventional setup through the firewall, but they did list the clevis separately, so I decided to take a look at vehicles that used that clevis and lo and behold I came across the FJ Cruiser, which uses a very similar setup to the Tacoma with one big exception: it uses a metal pedal instead of plastic.

Not only does the FJ Cruiser use a metal clutch pedal, but Toyota actually sells components for the master cylinder (overhaul kit, clevis), which for longevity and serviceability I consider to be a plus.

Here is the 31420-35070 master cylinder:



Worth noting is the fact that while most of the cylinder is metal, the clevis is plastic. (If you were really set on having a full metal setup, the 31420-60060 master cylinder from the 2008-2018 Land Cruiser 200 can be used, though it is not available from North American dealers -- you can "build your own" using the 31420-35070 master cylinder and replacing the clevis with part number 31404-35013).

Here's the FJ Cruiser clutch pedal:



Compared to the Tacoma clutch pedal:



If I owned a Tacoma, I would be swapping things out for an all-metal solution that is tried and true.

Here's the parts list for my "solution." Only parts that are different and/or required are listed.

31301-35270 - Pedal, Clutch (Steel)
90389-06055 - Bushing, Clutch Pedal Spring (Only required for 2005-2019 Tacomas produced before May 2019 that have not had T-SB-0186-12 Rev.2 completed)
90541-06036 - Stopper, Clutch Pedal (Qty: 2, Tacoma already uses one, FJ uses 3)
31420-35070 - Master Cylinder, Clutch (Alternate: 31420-60060, uses metal clevis in place of plastic)
31454-30030 - Boot, Master Cylinder (Optional, 2015-2020 Tacomas include this boot while other vehicles don't, but it seems worth having)
31434-60010 - Hose, Clutch Reservoir (Only required for 2005-2014 Tacomas that have not had T-SB-0186 Rev.1 or Rev.2 completed)
31404-35013 - Clevis, Clutch Master (Optional, all-metal design replaces plastic design that is included with 31420-35070)
90240-T0002 - Pin, Clevis to Pedal
90386-08033 - Bushing, Pedal Pin
90206-08001 - Washer, Pedal Pin
90468-15006 - Retainer, Pedal Pin

Service Parts:
04311-60180 - Overhaul Kit, Master Cylinder
31454-30030 - Boot, Master Cylinder
31404-0K010 - Clevis, Plastic
31404-35013 - Clevis, Metal
94120-40800 - Nut, Pushrod to Clevis

All 2005-2020 Tacomas use the same pedal arrangement (2WD, 4WD, 5MT, 6MT), so everything in this thread is relevant to those years/models (including the TSB itself).

Obviously I have not personally attempted to use the parts list I included here myself, so someone else will need to be the guinea pig if they're looking to give something a shot.

I hope some people can make use of this information.

Because pricing had come up previously, the approximate total for all of the FJ Cruiser pieces, at discounted online rates: $140, the total for the latest Tacoma TSB pieces: $258.

These prices are for OEM parts from Toyota USA sources that offer online-store discounts. Because this forum is for the 2016+ Tacoma, I excluded pricing optional items from the FJ Cruiser/Land Cruiser pieces and excluded the reservoir tube for the TSB items as it is not needed for any 2016+ Tacomas. Additionally, all Tacomas produced after January, 2017 already have the latest master cylinder, so for the TSB only the pedal and bushing would be required for those trucks ($173).

One last post on the topic here, since the TSB is not very specific about what is or isn't needed for each truck, they just say do all the pieces for all trucks, here's a breakdown for what is needed to update to the latest Tacoma design:

2005-2014 Tacoma without T-SB-0186-12:
31420-60032 - Master Cylinder
31434-60010 - Hose
31311-04021 - Pedal
90389-06055 - Bushing

2005-2014 Tacoma with up to T-SB-0186-12 (no revision),
2015-2017 Tacoma (up to January 2017 production) without T-SB-0186-12 Rev. 1:
31420-60032 - Master Cylinder
31311-04021 - Pedal
90389-06055 - Bushing

2005-2017 Tacoma with T-SB-0186-12 Rev. 1,
2017-2019 Tacoma (up to May 2019 production):
31311-04021 - Pedal
90389-06055 - Bushing

Nice work, Jeff.

I agree that JIT works well to on assembly lines and such with well defined rates.

There is a thread here about the FJ pedal swap. Due to the interfaces, it requires cutting and welding to work.

 

Nice op, may have to get mine looked at. It squeaks most especially when its cold out. Mine is fairly new though, Im only at 4500.

 

Interesting, most here experience issues when its warmer usually in the 90s here.
