with 52k miles. Friend had Subaru replace both head gaskets today (see other thread). Subaru said they heard a bad rear wheel bearing during the post-repair test drive. Quoted $322 to fix. Looking at the parts diagram, it looks like it has a sealed hib just like my Toyota and Lexus cars. Is that right? If yes, the job appears very straightforward for a DIY. Am I missing something (besides a few loose screws, that is)?
