Thanks for the reply fellas...but I don't think my front spacer/adapter unbolts. I think it is a one piece hub/rotor and spacer/adapter all in one. I think I would have to get a whole new rotor, or would a regular wheel fit on the hub/rotor/spacer/adapter I have? I'm confused on this one. A buddy has an E350, he mounted a regular wheel on the front. His rotor has no spacer/adapter as part of his rotor. Any help appreciated.

Is your rig 2WD? If so, then the hub and rotor are all one piece (inlcuding dually adapter.) To convert to non-dually front wheels, you'd have to change the wheel hub and rotor to SRW style, but I'm not sure they'd interchange on your spindles.

The 4WDtrucks the dually wheel adapter bolts on to the unitized wheel bearing/hub assembly, and the rotor is separate also.
