I have put ALOT of research into finding a more affordable source. The best replacements (I am talking about true wheel bearing manufacturers for automotive driven wheels) are NSK 30BWD10A, TOYOTA 9004A-36087, SKF VKBA7427, AND PFI PW30620038CS. I have spent some 12 hours researching this. I do believe it to be accurate and the SKF# comes with a new circlip. I believe SKF is Toyota's OEM but without bearings in hand I can't be overjoyed. My OEM repair went without a hitch. No damage present inside the trailing arm. Polished the sleeve with some 800 grit emery cloth and gresed the outside of the bearing to keep it from seizing in there like the last. All said and done I am a happy man. My bearings are gen2 by the way.
