It combines heat-treated chromoly spindles, serviceable Timken bearings and seals, and 35-spline, 1.50-inch outer axle shafts with DynaLoc locking hubs. Installation is bolt-on, with no machining or welding, and Dynatrac states the kits are made in the USA.\u003c\/p\u003e\u003ch2\u003eWhy convert away from unit bearings\u003c\/h2\u003e\u003cp\u003eA factory unit bearing is a sealed assembly. Dynatrac describes it as non-serviceable, impossible to inspect, and prone to failure, so when it goes bad the entire unit is replaced. The Free-Spin conversion changes the front end to a conventional spindle with separate inner and outer tapered roller bearings, races, and a hub seal, so you can pull the hub, inspect the bearings, repack them, and replace only what is worn. Dynatrac lists a smoother ride, better fuel economy, and longer axle life as benefits of the design. Those are manufacturer claims, and results depend on the truck, tires, and driving.\u003c\/p\u003e\u003ch2\u003eWhat is in the kit\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHeat-treated chromoly spindles\u003c\/li\u003e\n\u003cli\u003eCast nodular wheel hubs (8-on-170mm)\u003c\/li\u003e\n\u003cli\u003eServiceable Timken bearings, races, and seals\u003c\/li\u003e\n\u003cli\u003e35-spline, 1.50-inch outer axle shafts\u003c\/li\u003e\n\u003cli\u003eDynaLoc manual locking hubs\u003c\/li\u003e\n\u003cli\u003eWheel studs and mounting hardware\u003c\/li\u003e\n\u003cli\u003eABS tone rings and sensor mount\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDynaLoc locking hubs\u003c\/h2\u003e\u003cp\u003eThis kit uses Dynatrac's own DynaLoc manual locking hubs in place of the Warn Premium hub. Dynatrac says DynaLoc offers improved locking function, more strength, and a shorter profile, and that its short, custom-machined bezel gives the shortest hub stickout in the Free-Spin line, so the hub sits further inside the wheel and tire package and is less likely to be hit on the trail. Like any manual hub, you set it to lock for four-wheel drive and to free for the street. If you would rather run the Warn Premium hub, the Warn version of this kit is a separate listing in our catalog.\u003c\/p\u003e\u003ch2\u003eFitment for 2005-2014 Ford Super Duty\u003c\/h2\u003e\u003cp\u003eThis kit fits 2005-2014 F-250 and F-350 Super Duty 4x4 trucks, both single rear wheel (SRW) and dual rear wheel (DRW). Dynatrac states that its Free-Spin kits for 2005-2014 F-450 and F-550 trucks and for Ford dually trucks from 2005 on reuse the factory wheel adapters, so dually owners do not need an aftermarket adapter. The front axle is the Dana 60. The hubs are 8-on-170mm and reuse your existing rotor, and the kit carries ABS tone rings and a sensor mount so the factory ABS setup stays in place.\u003c\/p\u003e\u003ch2\u003eService parts are easy to find\u003c\/h2\u003e\u003cp\u003eDynatrac says every Free-Spin kit uses K30 bearings and seals, so replacements come from ordinary bearing suppliers. The common wear items are the Timken 387A inner bearing with 382A race, the Timken LM104949 outer bearing with LM104911 race, and the Timken 475960 hub seal. The spindle hardware is a Spicer 33732 six-point nut and 33733 washer, and the axle-end parts are the Spicer 700014 spindle needle bearing, 44506 thrust washer and seal combo, and 50381 boot seal.\u003c\/p\u003e\u003ch2\u003eBefore you order\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConfirm the truck is a 2005-2014 Ford F-250 or F-350 Super Duty 4x4 and that your model year falls inside that range.\u003c\/li\u003e\n\u003cli\u003eWhile the knuckles are apart, it is a sensible time to replace the axle u-joints and ball joints.
