FRONT HUB ASSEMBLY
2007 Subaru Outback • 4 cylinder AWD Automatic • 71,000 miles
Can you tell me how to remove and replace the front wheel hub assembly for a 2007 Subaru Outback 2.5i?. The dealer quoted $875 for 1 hub (Driver's side front). I see them online new for around $100-$150. It looks like it should be a 1-2 hour project. Is this a DIY project for a mechanically inclined do-it-yourselfer? (It appears to be as simple as: wheel nut - 4 bolts on the hub - hub puller - reverse. I am concerned about the anti-lock brakes and if separate seals are needed) thank you! Paul
