Dynatrac Free Spin hubs are a world apart. Many people who appear to be using their trucks under normal conditions -- stock tires and light-duty use -- have experienced failures within the first 50,000 miles of ownership. Officially, Ford says the unit bearings are a "normal wear" item, and therefore not covered by warranty at any mileage level. Furthermore, some dealers are approving the work under warranty on a case-by case basis. One-time repairs at a dealership can easily exceed $1,500.

Fortunately, there is now a fix. Dynatrac Products has designed a fixed spindle that is superior to the OEM live spindle. This design is similar to the hub/bearing assemblies we have known for decades. The new spindle is Forged from chromoly steel, and a cast modular wheel hub replaces the OEM unit. The kit uses locking hubs to engage and disengage the front drive. All Dynatrac Free Spin Kit components are made in the United States to exacting standards.

Installation Instructions for Dynatrac Free Spin Kits


Dynatrac engineers also upgraded the OEM 30-spline outer stub axle to a stronger 35-spline unit. The conversion uses all factory stock components -- rotor, caliper, and brake pads -- and is fully compatible with the stock ABS sensor. The bearings and seals are the same as those used on 1986-1997 F-350 4WD trucks, and are also common to many Dodge and GM 4WD trucks. They can be purchased at any parts house for about $65, and they can be inspected, repacked and adjusted as part of normal service.

Jim McGean, owner of Dynatrac, explained that the OEM sealed unit bearing had several problems. First, the two bearings are stacked right together, which decreases their mechanical ability to absorb the leverage exerted by the wheel. This is compounded by the large wheel spacer/adapter installed on the front axle, further increasing the leveraged force on the bearings.


Dynatrac Ford Super Duty Combo Kit - Dynatrac

Dynatrac’s Ford Super Duty Combo Kit addresses two major problems with 1999-2004 Ford F-250 and F-350 trucks. The Combo Kit replaces the OEM live spindle/hub assembly with a Dynatrac Free-Spin Heavy-Duty Hub Conversion Kit with a Dana 70 fixed-spindle designed for the loads and stresses of large tires and heavy trucks. Also included in the kit is a complete Crossover Steering Kit that markedly improves the responsiveness and precision of the truck's steering.

  • Greater strength & lower maintenance costs
  • Improved handling & control
  • Increased suspension travel
  • Higher ground-clearance
  • Uses standard truck wheel bearings and seals commonly available at any auto parts store
  • Sharper turning radius & smoother ride

Often, Super Duty owners with lifted trucks and bigger tires suffer from rapid front wheel bearing failure. The OEM, non-serviceable “live” spindle (a.k.a. unit bearing) is extremely expensive to replace, and will not stand up to big tires. The Dynatrac Combo kit includes Dynatrac’s Pro 60 knuckles and hubs in a fixed spindle design, which is specially set up for the loads created by big tires. Each wheel also receives a 35-spline outer axle shaft instead of the stock, 30-spline shaft and a Premium Warn manual locking hub to replace the factory units.

Customers will benefit from improved handling and increased ground clearance with a unique Crossover Steering Package that locates the steering linkage up and away from rocks and ground obstacles while improving linkage geometry. Dynatrac’s Crossover steering also minimizes bump steer, common in lifted suspensions. The package even includes an impressive, fabricated, dual-opposed steering stabilizer that is located above the beefy 1.5” diameter tie-rod assembly.

Each Dynatrac Combo Kit also includes a much longer, fully adjustable, and massive track bar compared to the tiny stock track bar. The reduced operating angles of the Dynatrac track bar eliminate binding in the leaf spring bushings and free up suspension movement that gives double the wheel travel of lifted suspensions without the Dynatrac kit.

Dynatrac Super Duty Combo Kits are immediately available and are compatible with all Ford Super Duty 4x4 trucks and Excursions fitted with popular suspension kits ranging between 6-12” of lift. The Dynatrac Super Duty Combo kit will also work on 99 to ‘04 Ford vehicles equipped with either the Dana 50 or Dana 60 front axle. This is a 100% bolt-on kit with no welding or drilling required. See our Free-Spin kits for trucks sporting stock suspensions and other ranges of lift.

NOTE: For those Super Duty owners without lift kits or large tires but looking for the same reliability and ease of maintenance benefits of our Combo Kit see our Dynatrac Free-Spin Heavy Duty Front Hub Conversion Kits for Ford Super Dutys

When factory specs don't cut it. 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. And all too often, the original equipment falls short.

  • Manual locking hubs reduce heat and increase fuel economy by preventing parts from rotating constantly during 2wd operation
  • Increases reliability by eliminating troublesome axle disconnect operation
  • Lower cost of ownership - wheel bearings and seal are dramatically cheaper to maintain, and can be easily serviced for longer life, even under severe conditions
  • Dramatic increase in axle strength and reliability w/ 35 spline1.5 inch shafts
  • All Stage 2 kits include Spicer 1480 series axle u-joints
  • Simple, bolt on installation. No machining or welding.

As an industry leader, Dynatrac has taken up the challenge of building the better truck. Designed specifically to remove a weak link in popular Dodge Ram 4x4 trucks, Dynatrac’s Free-Spin Heavy Duty Hub Conversion Kits replace the factory unit bearings with fixed spindles for superior strength, improved fuel economy, and smooth performance. The complete kit includes inexpensive, serviceable Timken bearings, cromoly spindles, cast nodular wheel hubs, Warn Premium manual locking hubs, and massive 1.50” diameter, 35-spline outer axle shafts. All made in the USA.

This combination of parts has been designed and tested to provide the best longevity and reliability under the most severe use. While the factory unit bearing is non-serviceable and prone to failure, the Free-Spin hub conversion offers ease of maintenance, a much smoother ride, better steering control, greater fuel economy, and longer axle and driveshaft life. Advantages that add up to tremendous cost savings over the life of your vehicle.

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 a ruined vacation or lost revenue for a work truck.

For recreational truck enthusiasts, the Free-Spin hub conversion eliminates a weak link that could easily leave you stranded. For commercial truck owners and fleet managers, who rely on their rigs 24/7 to get the job done, the Free-Spin hub conversion ensures that your trucks are on the road making you money. Improved Fuel economy and smoother performance is an additional bonus.
