Since I haven't had my rims off my truck, I don't know right off hand. Do the new F150s (2004+) use a hat style brake rotor on a separate hub or is the hub integrated into the rotor like nearly every other Ford? Also if it is integrated, are the bearings replaceable?

 

If you are talking 4x4, no they are seperate. The "hub" is an IWE (integrated wheel end) that is not servicable except for replacement. Don't know about 4x2. Haven't owned one of those thince '83.

 

Looking for info on a 2wd.

 

The two wheel drive trucks have the rotor and hub bearing integrated in one complete, sealed assembly. The rotor is retained to the spindle with a single 36mm nut. The bearing is not serviceable seperately, and it doesn't need to be cleaned/packed like the older two wheel drive trucks do.

 

Quintin, the 36mm nut says "DO NOT RE-USE" can it be re-used, or do I need to buy 2 new ones when I turn my rotors??

 

OK thanks.

 

I think its safe to that if it says " do not re-use ", you shouldn't reuse it.

 

Just an FYI, FoMoCo service manuals call for on-vehicle lathes for our trucks. Thus no reason to remove the rotors from the truck.

 

Damn Ford and their craziness..

 

I replaced mine. Remember, other than the caliper to spindle bracket bolts and the caliper itself, these are the nuts that hold the rotor to the spindle. Also note that the two wheel drive rotors are pretty tricky to turn off the truck, due to the design of the hub and bearing. The easiest, sure fire way is to resurface them on the truck.

Part number for the nuts is 6L3Z-3C294-AA. Torque to 295 ft/lbs, rotate the rotor counter clockwise five times and recheck your torque.

 

Yikes! I don't think my snap-on torque wrench even goes that high...(I'd have to check, though)

 

What about the 4x4?? Are they hard to turn off the truck?? Disk rears??

 

On the 4WD's, the rotors are separate from the hubs. They they come off easily, without need of messing with the hubs & bearings... That's also the reason that new rotors for 4WD's are a fraction of the cost of the 2WD's.

 

i think ford made a huge mistake by not making the 2wd rotor and hub assembly just like the 4wd. if fomoco is trying to keep costs down wouldn't it stand to reason that 1 type of rotor hub assembly for all f150's is cheaper than 2 separate assemblies for 2wd and 4wd?
