Built for trucks that work for a living, the Mevotech TTX wheel bearing and hub assembly, part number TXF40330, lets the front wheel rotate smoothly while carrying the vehicle's load. It is a direct-fit replacement for the front of the 2017-2018 Ford F-350 Super Duty, the 2017-2021 Ford F-450 Super Duty and the 2017-2021 Ford F-550 Super Duty. See the Buyer's Guide tab for engine-level details.
Mevotech engineers its TTX™ line for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks. These hub bearing assemblies use Labor Saver™ designs and hardware to make installation faster and easier. Fastening hardware and torque specifications come in the box.
A wheel bearing may need replacing if you hear a humming, growling or grinding noise that rises with vehicle speed, or if you notice play in the wheel. Diagnose the cause before replacing anything. If a worn Ford F-350 Super Duty wheel bearing is the problem, this assembly replaces the front hub and bearing as a single unit.
