I can 100% guarantee that there are no big buckets of random parts at the Subaru plant that Billy Bob (Kaito Saro?) could grab the wrong bearing from. They are a just in time, Kan Ban facility and if they need a stock of 100 an hour there are only 100 an hour on the floor. There will be zero old stock kicking around.

Did a quick look at some pics and there seems to be a very eclectic mix of the two tabs across the early years. Maybe two suppliers of the same part? I made the dealer order in the new part number and it had the solid tabs unlike their old stock that had the notched ones.

Yea I'm sure they were just trying to fill orders of the high demand for this car back then. Whatever part "fit" was suitable to use. Both types had the failed grease in them anyway, wouldn't have made a difference which one you got.

The tabs you guys are speaking of are purely for holding springs from the TOB to the clutch fork. These springs are used to reduce noise and hold no performance benefit to my knowledge. The springs ensure that constant contact from TOB to fork is kept *when the clutch is disengaged* (no load) to reduce and eliminate a rattling noise.
The WRX clutch and fork do not even use these springs. I've probably seen seven to eight, 2013-2016 TOBs and they have all had the solid tabs. The tab'd portion also is just one piece of the assembly; in which they (Toyobaru) could use any bearing on the inside regardless of which tab piece they chose out of the bucket. At the end of the day; I trust what the TSB states after testing the greases first hand and reading about the various common greases the bearing manufacturer can use. Thanks, Eric |

Never had any doubt the grease was the issue but your experiment sealed it for me. Not arguing or disputing your results in any way just exploring some possibilities. If the parts were mixed for all years then that avenue of speculation is closed.

Will the dealership install the updated bearing for free or reduced price under the TSB for cars out of warranty? I purchased my 2016 in Oct 2015. I was quoted $1600 to replace it (12 hours labor flat rate)!!! But I didn't mention the TSB.
My TOB is starting to squeak/squeal when the engine is cold but quiets down after it is warmed up. How long before it completely goes? I have 77k miles on it now... I have a trip to Vegas planned in 1-1/2 weeks and I don't want to break down in the middle of the desert... TIA |

Everything still looked "good" inside my tranny. No burns, warping or discoloration of the metal. Only the TOB looked worn, but not warped/bent.. And it was still spinning freely & easily. It just didn't spin "quietly", which means the grease was probably breaking down but not completely yet. If I were you though, no need to keep driving on it.. I'd just rent a car to go to Vegas. |

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

I guess 2013-2016 unused TOB can be got only by ordering new. Imho it makes little sense to buy one just for sake of unassembling/comparison, instead of buying latest revision TOB for actual use.

That grease was fine. It's pretty obvious when grease goes south.
