Front Hub Extension to Wheel Hub Fit Issue

[JohnHaggerty]

I can't get the second hub extension onto the wheel hub assembly. The hub assembly is on the truck. The first one went on no problems. At first I thought I might have caused the extension to become non-flat, but after some inspection it appears ok. The extension does fit onto the original wheel hub assembly. So I'm thinking the studs are not projecting normal causing it to bind at the stud to hole fit. Any thoughts or ideas? I purchased Timken brand assemblies from Rock Auto. Thanks, John

I tried again. Made sure the mating surfaces of the extension were clean and smooth. Applied plenty of anti-seize. Again got to the same point. I still need to gain about 3/16" for the surfaces to mate. I'm using the 8 nuts to jack down on the extension and plenty of wacks with a 2x4 and sledge hammer. I don't feel comfortable torquing the 8 nuts any more. Thanks, John.

Are you sure you got two of the same hubs? Do they measure the same?

"Stupid is what stupid does"! Don't forget the rotor.

Oh man, got a good giggle on that one.

Glad you got it figured out.

Did you ruin the adapter?

Did you ruin the adapter?

I have a flat plate of MIC 6 aluminum jig plate here. It didn't look bad resting on the plate. I probably did yield it locally a small amount. I can't get a torque wrench on those nuts, so I just laid into them. Looked tight all around when tight. I'm sure they are beyond the torque spec.
