Sorry this kind of got put on the back burner as I finish up other projects, I looked at a Tribeca rear knuckle but it was totally different, I kind of resigned to the fact that the R180 will be hard to swap in with bolt in parts. I may sell my LGT and build the WRX instead.

Having a communication error on my 05 LGT. I have successfully downloaded and uploaded maps using EcuFlash, however I cannot get my Bluetooth, USB cable through Learning mode, nor a wired OBD reader to connect to the ECU. Bluetooth OBD gets power, connects to my phone, and the Torque program can see the ECU but it fails to find a protocol to read it with, I can see it cycling through different OBD protocols (J####, CAN, etc). Wired OBD reader is similar, gets power, sees ECU, cycles through protocls but can't find one Openport 1.3 cable can flash maps but I get an error with Learning view when I try to read DTCs. I also cannot log on RomRaider, it gives me a failed to communicate error. I haven't checked the fuses yet but the OBD port is clearly getting power.

I reread all your posts, you machined the rear hub and made an adapter which I'm trying to avoid. I'll need to take apart my rear hub to take measurements but I'm pretty sure there's an easier solution that no one has tried or reported. Edit, bought a spare LGT wheel hub and took measurements The 04-07 STI bearing will not fit in the LGT stock hub, LGT hub ID is too small as well as being a roller bearing vs the STI taper bearing. Dimensions if anyone else wants, these are somewhat rough. Both of the inner races are machined into the stock carrier, it's pretty much not viable to find another bearing that will fit. I know some of this maybe old info but I couldn't find anything in my searches. LGT Inner bearing: .596" deep, OD 2.796, ID 2.499 LGT Outer: .662" depth, OD 2.664, ID 2.523 FWIW to use a STI bearing you could machine the LGT carrier to 2.83 ID and push in the whole STI hub/bearing. The only hiccup is that the GD STI uses circlips to lock the bearings in place.

Ok I'm bumping this for more info on this Timken part. I see that the rear on the LGT is a cartridge bearing which is nice; are you saying that if you buy the cartridge bearing and press out the hub + bearing that it comes with in theory the STI hub bearing will fit? Is it TIMKEN HA590119? If so that's easy and I already have all the parts from my 6mt/5x114 swapped (but hit by a drunk driver) 06 WRX wagon. The STI rear wheel bearing is readily available, the hub is a Subaru part only 28462FE011. These are the 04-07 STI rear wheel bearing specs: Width 2.054" Outside Diameter 2.8340" I'm also questioning the need to make the adapter plate if the 08+ STI uses the same OD size bearing as well, you can push out the hub+bearing from that set and put it into the carrier for the 05-09.
