When factory specs just don’t cut it
Q: Should I be concerned about exposed ABS tone rings?
No, it is not better to have the tone ring enclosed. This is a commonly misunderstood issue.
ABS ring seals aren’t great and frequently do a poor job of keeping debris out. If debris gets in and can’t easily get out, damage could occur. We believe that exposed ABS rings can easily shed water and debris that a seal might retain.
In fact, the tone rings on the rear of many Dodge trucks and millions of other vehicles equipped with 4-wheel ABS, are completely exposed to the elements. Vehicles with older 3-channel and single-channel ABS systems have a single rear sensor that plugs into the rear diff. Newer vehicles with 4-channel, 4-wheel ABS usually have a sensor at each rear wheel, near the brakes, that is completely exposed to the outside world.
The stock tone ring on the front of Dodge, Ford and GM trucks is enclosed inside the front Unit Bearing because that is the least expensive way to package and deliver it to the assembly line. This is true whenever a Unit Bearing is employed on the front axle by the OEM.
Q: My truck has the factory auto locking hubs. Why would I want full manual locking hubs?
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. They also frequently fail to unlock. This leads to additional wear and tear on your front end and drive shaft and a decrease in fuel mileage.
Q: Where can I find replacement parts?
Your local parts store should have everything you’ll need. You’ll find a full listing of part numbers with your installation instructions. We also have them posted here (link to instruction page).
Q: How frequently should I service my Free-Spin™ kit?
40K or sooner if it’s severe duty and in cold environments. When you service the Free-Spin™ kit you should repack the bearings, fill the hub with fresh axle grease, and inspect for wear.
Q: Can I install this kit myself?
A good ‘backyard mechanic’ can do the job in about a day. A competent shop time can usually get the job done in 5-6 hours.
Q: Will I need any special tools?
A good set of hand tools and a few specialty tools are required.

Q: If I have a unit bearing failure, what other damage can occur?
If the unit bearing failure is caught very early it is possible that you may see no other damaged parts. Complete unit bearing failure may cause the tire and wheel assembly to fall off of the vehicle. Damage to the brake pads and rotors are very common with any type of unit bearing failure.
Q: Is there a Free-Spin™ kit for Dually applications?
For F250 and F350 dually applications you’ll need special wheel adapter. This adapter can be found at http://www.arrowcraft.com/products.php or by calling them at 248-280-0210.
