I am replacing right front hub and ball joints on my 1999 F350 Super duty crew cab. This will be the third change, I will not get into the weeds on why I am replacing, as that is another story. Upper ball joint had torn boot and was in need of replacement, another story for another time. I bought a SKF assembly from local NAPA store, all looked good and install went fine, when I put tire on and tightened down the wheel would not spin, not even a budge, I spent the next two hours trying to figure out the problem, caliper on, caliper off, disc brake shield moved, bent, etc. No matter what I tried the tire would not rotate with any torque. I finally decide to measure the thickness of the hub face where the wheel studs are screwed into and compare to old one, I'll be damn if they were not different, old one measured .523" and the new SKF measured .406. I believe this is were the binding is occurring, it is rubbing on the outboard side of the caliper. Has anyone run into this issue? Is there a difference in hub flange thickness? I have changed out both sides and never have run into this issue.
May have found the issue, I believe I need a SKF BR930420 not the BR930426 NAPA gave me. I specifically told the the parts guy late 1999 as my truck has a build date of 04/99. Will wait and see what they have to say and what the other hub measurement are.
Someday would like to upgrade to the Dynatrac. At 217,000 on pickup and haul a camper many times a year, not to bad on the hubs? This hub actually was fine after pressing it apart to find why there was roughness and small rough spot, the Timken bearing and race were like new, good grease and seal was fine, not sure if the tone ring had something inside it, but the hub bearing was good to go. Definitely was the early 1999 hub, thru 03/1999 versus the late, post 03/1999 that was the issue, they changed the hub flange thickness by over .100 and this caused a bind between rotor and caliper.
Slide-in camper on a dually F350 is the reason I converted at around 215,000 miles few years ago.
The front Dana 60 has factory "hub extensions" - see the photo below.
The one on the right is the original factory extension which was not compatible with the new hubs. Ended up switching to Arrowcraft version (on the left) which is compatible.
I was not comfortable with the combination of unit bearings & extensions.
Maybe it's fine when everything is relatively new but after thousands and thousands of miles and 4500 lbs slide in camper in the bed it was not for me.
