The new Timken bearings were packed with grease the old-fashioned way-by hand.
Finally, the stock calipers were reinstalled. Spacers are provided to ensure proper clearance between the pads and the brake rotors. On our F-550, the small tabs on the dust shields that cover the ABS wires needed slight trimming so they would not rub on anything. When the kit is correctly installed, there is no effect on wheel alignment. For Super Duty trucks with big suspension lifts, the original Dynatrac Super Duty Combo Kit is still available. This requires changing steering knuckles and the track bar, and takes considerably more time. The conversion we installed required no welding, drilling, or grinding.
The complete kit comes with detailed step-by-step instructions. The only special tools required are: a six-point spanner socket (OTC #7090-A) or a four-point spanner socket (OTC #7158), depending on which style spanner nuts your hub needs; a torque wrench that will go to 140 pounds; and a race driver like the one made by Snap-On (#PPC14LA). Note: Tools needed for the Dodge kit may be slightly different.
The Dynatrac Free-Spin Hub Conversion kit for Ford fits all Super Duty 4X4 trucks from '99-'04. A kit for the '05 and '06 Super Duty (which, despite a larger bearing, still suffers from the same problem), is being developed. The kit costs $1,695.
A Free-Spin Hub Conversion kit for the '94-'99 and '00-'05 Dodge heavy-duty trucks is available, with the added benefit of giving Dodge truck owners manual locking hubs. These will help increase fuel economy and reduce wear and tear. In other words, the axleshafts, gears, and driveshafts won't be constantly turning with the hubs unlocked. The kit costs $1,795. Both are available directly from Dynatrac or any of their dealers nationwide.

A replaceable seal on the back of the needle bearing housing allows the bearing to be repacked with grease at normal intervals. |
