Thanks for all of the info. Tech Mod, that is a great web site you gave. It sounds as if, from this info and talking to the Sabaru dealer today, they have gone to a tapered roller bearing that can be damaged if not installed properly. The dealer said there is no hub assembly with bearing avaliable for my car, so that doesn't seem to be an option. They did say they had had to buy special OTC brand pullers for this job which is mentioned at the web site given. Mine was installed by a knowledable shop, but does not deal specify with Sabaru's, I think that was my mistake. Since I just wasted $400 a year and a half ago and knowing this is a problem area that takes special pullers, I'm going with tha Sabaru dealer this time. Thanks again for all the input.
