Alright Ford Expedition and Lincoln Navigator owners from 2011-2014, if you're hearing unusual noises from your wheels or feeling vibrations in your steering wheel, it's probably time to replace those wheel bearings! This A-Premium hub assembly is specifically designed for the rear wheels of your vehicle and comes with everything you need for a proper fix. It's a 6-lug design that fits perfectly with your current disc rotors, wheels, and nuts, and it includes the ABS sensor so you don't have to worry about your anti-lock brakes acting up. The construction uses GCr15 steel and 65Mn steel materials that can handle serious axial and radial loads - meaning it's built tough for daily driving conditions. Each assembly comes pre-greased with new CV axle splines, bearing cages, and sealing components to solve those common problems like noise, vibration, and grease leakage that happen with old, worn-out bearings. The reference part numbers are 541013 and SP550218 if you want to cross-check compatibility. Installation is pretty straightforward if you're mechanically inclined, and A-Premium backs it up with a one-year unlimited-mileage guarantee for peace of mind. Seriously, replacing worn wheel bearings isn't just about comfort - it's a safety issue that affects your vehicle's handling and braking. For the price compared to dealership parts, this is a solid quality replacement that'll have your SUV driving smoothly and quietly again.
