Don't risk using them. Now I know why the return period is so short. Both are out of service, Chinese junkyards and are failing. If you have them, be sure to test them under load, turning them fully left and then fully right up to the steering wheel when cruising slowly; I heard a grinding noise that got worse very quickly the longer I drove. I had to rip them out to replace the Japanese made Subaru OEM bearings with Koyo bearings. They're not worth the few bucks you save on the OEM. I would give zero stars.
