Pilot diameter on F350 dually rear hubs???

JD Seller · Jun 4, 2016

I had an aluminum wheel come loose on the right rear of my 2000 F350 dually pickup. The studs and wheels all are junk. I am needing to know the minimum diameter for the pilot diameter that the wheel center rides on. These are center pilot centered wheels. The hub does not look damaged but I want to makes sure. I am replacing ALL four rear wheels with steel and getting ride of the aluminum wheels. They are pretty but they will not take the loads as well pulling trailers. I have only broken studs on two pickups trucks in all the time I have owned trucks. Both times it involved aluminum wheels.

Can't believe you had Ford aluminum duals come loose on you. I cringe every time one rolls into my shop, usually means an hour or two of hammering, prying, and swearing.

This truck has steel rims on the inside and aluminum rims on the outside. I just have had it running the last 3-4 weeks. Still working all the bugs out of it.

I have 2 aluminum and 2 steel on the back of mine too. I never have had a problem with them coming loose. Weight shouldn't have anything to do with it. I pull 24000 behind mine all the time. I pulled 32000 for 200 miles once. I put a load of pipe on the trailer and didn't weigh it until I got home. I've had the same wheels for 17 years. Something else is causing your wheels to come loose. I agree with Sprint 6, they're not easy to get loose. Make sure that the hub face is flat. I will try to measure my hub diameter for you tomorrow.

That is the way they all are. Usually galvanic corrosion has them welded to the hub and the steel wheel.

There is only one wheel that fits 99 up Fords,no Chev.or Dodge wheel will fit, Different bolt circle.Your lug nuts weren't tight to begin with,because those wheels just don't come loose on their own as others have said.

You have issues other than aluminum wheels. Something is a factor in them getting loose. Not tightened properly: dirty mating surfaces: bent or warped wheel : bad brake drum, etc... I have had no issues with my'02 F350 and am 25000# up very often. Also: we have aluminum wheels on semi trucks that are much heavier than you will ever be. Aluminum is not the problem.

Bolt a rim on and check it with a dial indicator, loosen, turn tighten and check a few times and you will know if the wear is going to be a problem.
Something as simple as someone getting a little too aggressive sanding/cleaning things up can be enough to create a centering problem.

Torque the nuts, drive around the block and torque them again.
Drive 100 miles or so and re-torque, another 100 miles do it again, if you get so much as a degree of rotation when you re-torque keep doing this until when you check them they are perfect.
Now you can put on your fancy center caps if so equipped and drive it with confidence.

I think it's 170 mm pattern. Can't recall anything else about it.
