86 F150 wheel bearings

Post #1 by SteveP » Fri Oct 21, 2016 11:08 pm

I'm doing a suspension overhaul on a 86 F150 2 wheel drive, including brakes. I ran into a situation I've never encountered before and I hope that someone can give me some insight.
When I pulled the front rotors to have them turned and repack the wheel bearings the spindle nuts were torqued tight. I've been a mechanic all my life and I know how to adjust wheel bearings so this raised a red flag.
The spindle has a shoulder on it that lines up perfectly with the inside race of the outer bearing when the bearings are seated. I verified this by removing the nut and washer and feeling it with a finger tip.
With the nut and washer tightened to this shoulder the rotor feels right when I rotate it, not too tight, no binding, and spins freely.
I don't have a manual so I've been looking online to see if there's anything special about the 86 that would mean I don't have to adjust the bearings, but just torque the spindle nut down. Everything I've found references the usual adjusting procedure with no mention of any shoulder on the spindle.
Does anyone have access to a manual to verify the correct procedure to follow here?

Hi, I'm with you. I've only seen normal spindles where the outer bearing slides on the spindle and the threads are pretty much the same diameter as the inner bearing diameter. The keyed washer usually slides well into this area. Never saw what you got. So you don't set a pre load. What if the cotter pin doesn't line up? Good luck

I've never seen anything like this either. That's what has me wondering what to do.
The nut isn't castellated. It has a separate retainer that that the cotter pin goes through. Lining it up is no problem.

Well it's lasted this long so I guess you have to go with it. Good luck
