How do you use your truck? It might a recreational tow rig, an off-road explorer, an industrial workhorse, a daily driver or a combination of them all. No matter how you use your truck, the engineers at Dynatrac understand that the measure by which all parts are judged is strength and performance. From light duty to extreme use, your vehicle should be built for reliability and endurance under any conditions. All too often, the original equipment falls short. As an industry leader, Dynatrac has taken up the challenge of building the better truck.
- Designed specifically to remove a weak link
Dynatrac's Free-Spin Heavy Duty Hub Conversion Kit is designed replace the factory unit bearings with fixed spindles for superior strength, and smooth performance.
- What's wrong with the unit bearings?
Unitized bearing systems, also known as unit bearings, were designed to make vehicle assembly easier. When assembling a vehicle, the installer simply mounts the unit bearing up the steering knuckle with 4 bolts and the brakes are ready to install. This saves the OEM time and time IS money. Despite the added cost of the parts, the time saved can add up to additional profits for the manufacturer. But, as most have found, faster doesn't always equal better.
- Unit bearings are prone to failure
Due to a very narrow bearing design and plastic bearing cages, unit bearing systems are much less durable than a fixed spindle design wheel bearing system and cannot be serviced or regreased. This is especially important on a truck that has larger than stock tires. Worse yet, replacing a unit bearing is very expensive. Buying original equipment parts is incredibly expensive and many users end up buying more cost effective, but still very expensive, units bearings made overseas. These units are usually much poorer quality than the OE product and long term durability may be questionable.
When a unit bearing fails, the vehicle is often immediately disabled and cannot be driven anywhere until the unit bearing has been completely replaced. That means towing, downtime, expensive dealer repairs and could cause a ruined vacation or lost revenue for a work truck.

The factory Ford vacuum disconnect hubs are a well known trouble spot on the Super Duties. They frequently fail leaving you without 4 wheel drive when you need it.
