Throw out bearing comparison old vs new

Must be a Subaru pricing thing. The Toyota one is $21

It pays to shop both suppliers for parts. Sometimes one or the other can be much cheaper. Doesn't seem to be a pattern though.

All in who's label is on the parts Subaru makes most of the parts, but Toyota makes the driveline. Although strange Subaru has been using the same TOB part number since 1990 in 476 different models

Subaru doesn't make any of the parts. Their suppliers do.

Thanks for all the research. Real interesting.

Not all 2017s have the updated parts, it was switched mid-year. see T-SB-0219-17

The sooner it is changed the less likely you are to have catastrophic failure like I did.

Sigh... This is just another issue that makes me wish Toyota had stuck their driveline (an upgraded 3SGE- 4SGE?) in the Scion versions. Hell, I'd even be happy with a W58 transmission (old, old, old 5-speed used in the 80s for those of you not familiar with old, old, old Toyota technology).

Well that would seem nice on the surface but they were not without issues and the bullet proof memories are more nostalgia than fact. The old tech would still be old and not live up to it's rep way back when.

I mean 2013-2016 TOB unused VS 2017+ TOB unused should be a more comparable match.

The unit I cut apart was out of my car, the shop car, with ~13k miles on it. The BRZ is a 2014.

Oh, I dunno if I agree that "bulletproof memories are more nostalgia than fact".
It is a fact of engineering that anything and everything that can be made faster, lighter, cheaper will be until you go a little too far making it faster/cheaper/lighter. Then you start over. Every engineering student has watched the video of the Tacoma Narrows bridge.
The TOB assemblies in my older Toyotas never gave me problems. My 1988 truck went 175k miles before the clutch was replaced due to a leaking main seal contaminating the clutch surface. There are no tabs on the bearing. It's just a big fat thrust bearing pressed on to a big fat, cast (forged?) bearing carrier that slides up and down a lightly greased steel tube pressed into the front transmission bearing seal. I've no doubt that someone looked at that and thought, "we can make that assembly faster, cheaper, lighter..." but in the process they also thought, "we'll call it a wear item and give it an expected life of 36 months or 36k miles, whichever occurs first."
Same goes for the VVTi and DI systems. My 2011 Yaris had the VVTi and DI. It never had the death rattle (see my thread, 0W-30 oil, in the mechanical maintenance section) nor the crickets in the 140k miles I drove that car until it was totalled in a rear-ender...
So, I agree with you that resurrecting old tech is a non-starter. But not because it would "not live up to its rep" but because it would increase the cost of the car to a point not many people would buy one.

My TOB finally went out around 65k miles. Decided to change the clutch too. The clutch doesn’t look bad but man the TOB nuked itself and destroyed one of the clips. I’ll get some pics tomorrow.

So I had my bearing replaced at juuussstt under 36,000 miles due to this premature "failure" issue. Unfortunately they replaced it with the same old part number, as this was done just before the TSB was issued. I'm now at 62,000 miles. What are the odds I can talk my way into having it replaced again? Probably slim...

Here's a link to a thread I started on this topic. I recently purchased the Exedy OEM replacement FJK1005 kit which appears to come with the revised part. I'm not sure if all of their stock has been revised yet or not so it's worth checking and then buying the part from Toyota/Subaru if you did not get the revision in your kit.

Edit: Disregard, the bad TOB and revised appear to both have shared the same type of housings so without seeing the white dot on one of the tabs, there's no way to know if it's truly the revised version.

correct. NTN is the manufacturer/supplier for the release bearing.
