Will Genuine Subaru steering rack boot 34135FC000 (one per side) fit a Subaru WRX (GD/GG, 2002-2007)?

Q: Will Genuine Subaru steering rack boot 34135FC000 (one per side) fit a Subaru WRX (GD/GG, 2002-2007)?

Yes, reportedly. The dealer-supplied Subaru parts catalog lists boot 34135FC000 (diagram code 34908A) for the 2002-04 Impreza WRX and the 2004 STI, two per car, and also for 1998-2004 Impreza and 1998-2002 Forester. An Australian parts site lists a Mackay aftermarket boot kit (SB004: 180 mm long, 43 mm at the rack-housing end, 8 mm at the shaft end) for GD WRX sedans and GG wagons from 2000 to 2005 (Australian build dates). The catalog's replacement steps: lift and support the car, remove the wheel and the outer tie-rod end, swap the boot with new clamps, refit the tie-rod end, then check the alignment. Counting the turns as the outer tie-rod end comes off helps keep the toe close until the car is aligned. We found no source that confirms this part number for 2005-07 cars, so check by VIN for those years.
