Best replacement TOB
 

My TOB is going out. I know that Toyota have an updated bearing ( different grease).
Are there any other OE suppliers offering as good or better quality?
I’d rather do this job only once in my lifetime.

Unfortunately with a manual transmission, the TOB is a wear item. Just like the clutch- you can't expect to never have to replace it. The updated part should last a very long time :iono:

There is no aftermarket TOB. updated bearing is your one and only option.

I upgraded to an OS Giken clutch when my throwout bearing went out. The kit is expensive but it included an entirely differently designed TOB, clutch fork and clutch line. Also with how light the assembly is made it worth it in my mind.

Go to your local subie dealership or toyota, or call them, and place the order through them. I suppose you could get one on amazon, but I'd rather get it right from my local dealer because I dont want to wind up with some weird third party part. Oem parts are ALWAYS the highest quality parts there are. Aftermarket engine air filters as well as aftermarket oil filters are trash. Nobody here will say a simple positive thing about k&n filters.

Someone in the past recommended this SKF unit

Is there a production date that the "updated TOB" began to ship with? I've had no such problem with my TOB so far in my car (2015 MY, 08/2014 production month), but I see OP has a 2016.

Wear item perhaps now a days, but after 49 years driving standards each up or exceeding 300,000 kl. I’ve never had to replace a clutch or TOB.
At only 60,000 kl., and to be looking at this repair you might understand my concern.

An aftermarket air filter must have done you wrong for such a pointed tangent. lol

I 100% agree with you. While I've had to replace them on a couple previous cars, it was due to them just having been driven hard and who knows how the previous owners treated them as well, I certainly drive my cars hard so I know it's my fault when something breaks.

Regardless of the past, these cars have a penchant for chewing up the TOB. Each platform has unique needs and stressors - for older BMWs, it's the expansion tank and cooling system. Why would anyone think a clutch driven fan or expansion tank is a wear item? You will, when the car overheats because your fan grenaded and took out the rad.

Or a more obvious example - why would headlight brackets be a wear item? Well ask anyone who has owned an NA Miata. When their headlight keeps going down randomly, they'll have torn that thing out and replaced the whole assembly.

I know my point likely falls on deaf ears, but understanding the strengths and weaknesses of the platform is part of the fun, no? Unless your platform is the RX8 and the weakness is the engine.

The OS Giken TOB is a significant upgrade, but only works with OS Giken clutches due to the stack height.

Will all cars with that clutch feel the same in terms of pedal pressure and travel?

Nope; it depends on the pressure plate used, the number of clutch discs, etc.

However, they will all rev up and down a bit faster than stock, due to the reduced inertia of the clutch setup.

My car uses a hard cover; the soft cover would have a lighter pedal and a winder engagement window, at the cost of reduced clamping capacity.

Even that reduced capacity would easily handle FI, and be more than enough for NA.

I think depending on cost my next setup should be the lighter version of that.

To me, you’re lumping poor engineering/ design failure with Wear Items.
Everything will fail eventually. But let the rust come first. 🇨🇦

Just buy the new bearing. It’ll last with the upgraded grease. Just make sure it has the white dot.

I have the new one and it’s about 2 years old and starting to die again. That Tilton rig is looking attractive.

Two years? How many miles a year are you driving? It had the white dot?

My "updated" OEM bearings were going out regularly too.

OS Giken bearing has been in for quite a while now...

There’s some discussion out there that it might be the stock clutch fork flexing that’s putting unintended loads on the TOB and causing them to die early. Has anyone run into issues with the updated TOB and a forged clutch fork used together?

Thanks for the input All.
Winters coming and I’ll likely put her into hibernation next weekend.
I’ll have months to research/source parts and tools for a Spring project.
Only ~65,000 kl. on the car but may just upgrade the fork, pivot and clutch while in there.
Has anyone used the transmission lift adapter available for a floor jack? About CA$80 at Princess Auto.

Does anyone have experience with the Sachs bearing? A friend of mine uses them and says they work great. They area apparently much heavier and better built than any of the OEM versions.

Money Shift Racing made a hydraulic TOB conversion at one point. Maybe you could contact them?

discontinued afaik.

dangit. it was on my "while i've got the trans out" list that had another 20k miles before it was due...

My understanding is it was discontinued due to a lot of failures.

I see. I assumed it had been discontinued due to a lack of buyers

Do not buy this one. I had it on my car and it failed. It worked great the first 100mi or so but it started to get crunchy and also started squealing. The idea is great, and I really wished that it worked but in the end go with OEM.

I don’t think I could put anything on my car from a company called Money Shift. Bad Juju.

At how many miles are people having TOB issues?

70,000

35,000

I saw Sachs listed at an online parts supplier here in Canada but no other manufacturers yet found. Them being the only one was leading me to think that they may provide the OEM bearings to Toyota/Subaru. But if they differ then perhaps not.

The Sachs unit is most definitely not similar to OEM.

Yes, upon further investigation, that website I mentioned actually describes the Sachs as “oversized”.
Also about 5X the price of OEM. But surely worth it if it lasts.

95,000mi

I'd say that's a good life for a tob. Replaced it with another exedy. 10k miles in no issues.

Best replacement TOB
 

Sorry for the slow reply. I’d have to check to be sure but I’d say about 28k miles. I still haven’t replaced it but it’s making all kinds of noise now. I’ve been too lazy to deal with it. But yes it was the new part number with the white dot.

In the FRS my first one lasted about 40,000 miles. The second about 100,000.
If going OEM just make sure you get the most recent part number. There are at least 4 different versions of OEM floating around out there. Even the white dot one has been replaced with one with no dot. It is a crap shoot really.

The 2nd TOB on my FRS is about to go out. This one has around 55k miles on it now. As I remember the original one had a little more than that. Has there been any consensus on exactly which part number lasts the longest? Doing this every 50k miles or so is ridiculous.
