front wheel hub assembly question??

[melmount]

Whats the difference in the front hub assembly from the srw to a dually?
Looking on ebay at the hub and bearing assemblys. I have a dually they state for a srw truck on almost all of them.

4wheel abs and the way they bolt up.

will all 4wd's have 4 wheel abs? do all duallys have 4 wheel abs? I figured that 4wd and abs was all that mattered. I guess the dually does too??
just verifying, one is starting to go.
thx

no, not all 4wd's have abs and the dually hubs stick out farther for proper spacing of the rims if I'm not mistaken.

you can put an abs hub on a non abs truck and cut the wire but you can't put a non abs hub on an abs truck

the only real difference is how they attach to the front axle and where the ABS sensor is located. other than that there is no real difference in them. the dually wheels require more back spacing than that or a srw.

My dually front hubs have 3 inch(approx) spacers bolted on. That way they can fit the dually wheel.I know I have to put the hub spacer back on. I just figured their would be a lot less choices. I need the abs stuff on the hub
