As the title states, 01 STI forester with the 4/2 brakes. Sounds like one of or both of my wheel bearings are in the early stages of wearing out.

Tough to find information on compatibility but are they the same as a regular USDM forester or possibly WRX?

Hopefully someone has some information to guide me into finding a place to buy.

      Awesome thanks. Took apart the rear today. Looks like my caliper is actually partially seized. Going to replace the caliper. Since it's the 1 piston rear caliper it should be the same as a USDM forester

          So I can confirm that the udsm rear caliper is NOT compatible, the gap from the piston face to the other side of the caliper on the JDM is 2", and the USDM is 1.75".

          I can't seem to find any information online that says what USDM caliper is the same as the JDM one. I thought it might be the same as a WRX or possibly a Legacy GT I have CTR bringing in some different calipers to compare.

          If anyone knows what is a compatable replacement that would be great. I bet it would be hard to source a reman jdm caliper.

          EDIT.  https://forums.nasioc.com/forums/showthread.php?t=916507

          According to this since I have a 10.5" diameter vented rotor with single piston caliper that a USDM Legacy GT should work.

            Most engine parts are similar to the 2002 WRX. Most 02-07 WRX suspension parts fit gc8/gf8/sf5. But you learn something new every day.
