Perfect fit for my 2001 Toyota Camry with 4 cylinder engine and rear drum brakes without ABS. Supplied ready to install with grease already packed in the bearings. A new o-ring is not supplied, so you may need to replace the o-ring. My o-ring wasn't damaged so I just took it off, cleaned it, put some lube on it and reinstalled it. The bearings run smoothly and quietly.
