Installation

Installation of the rear wheel bearing seal typically requires removal of the rear hub and bearing assembly. This job is recommended for experienced DIYers with access to a hydraulic press or bearing/seal driver set, or a professional automotive technician. Proper installation depth is critical to ensure the seal seats flush and functions correctly. Always inspect the bearing and surrounding components for wear while the assembly is disassembled, and replace as needed to restore full drivetrain health.
