I have a 1994 ranger xlt 4x4 with locking hubs I want to put wheel spacers but don't know haw it would work considering the lug nuts hold the hub on the Axel. Haw do I go about doing this?

 

The spacers would go between wheel and hub.
You need spacers with large enough center hole same as you need wheels with large enough center holes to clear the hubs

You may need to pull the hub to put on longer studs, but up to you.

If hubs will be buried, so hard to lock and unlock, just leave them locked, won't hurt anything, 2001 Rangers and up have permanently locked front hubs

 

Then hub is two fir away from the axel and won't engage would it work if I put them on after the hub so the spacer is between the Hub and rim?

 

spacer bolts to lugs already on the hub, most spacers have there own lugs that you put the wheel on

 

Leave lock/unlock "hub" in place on the truck, place spacer over it, then put on wheel
