Dually Problems

[MurrayPro92]

Hi. I have a 1969 Dually bumpside and have a problem with vibration at higher speeds. I noticed my original wheels are gone and in they're place are some 90's Ford dually wheels. I know the factory wheels have beveled edges and such that helped center the wheel on the hub, these wheels it has now do not have that and I wonder if that is causing my vibration? I need to put new studs in the rear and while I am that far in what can I do about the wheel situation? I'm not very savvy about this so pardon the dumb questions. Any help would be appreciated! Thanks!

Sounds like you have hub-centric wheels. They can be made to work, but you're better off tracking down some lug-centric wheels that center themselves as the lug nuts are tightened. They're sometimes called coined wheels.
This has been discussed before - here's the link. Hope it helps.

Yes that is definately at least some of the vibration if not most of it. Your present setup is a bit of gray area as far as these old bump duallies go. Those aluminum rims can be made work. But I think you will find that the expense and effort can be a lot more than just finding the correct rims. Those aluminum rims being aluminum are eventually going to wallow out the holes with any amount of use and each vibration will eventually speed that up in my opinion. If the look is what concerns you....stainless steel wheel covers can be used. just look for ones to fit a dent era truck with the same size rims.
I went thru a similar experience with mine and its not a cheap fix but one well worth doing if you plan on using the truck on a regular basis. You took on a pretty tough job with that dually. It helps a lot to try to look at money spent as peace of mind if you are going to run it regularly. Just remember that the vibration is slowly eating away at every moving part involved......I am guessing the steering mostly.

Edit.....Sorry.....I just now noticed some pics in another post of yours showing the steel rims.....but the same applies.....much better to find the correct ones.

BTW....what is prompting the stud replacement on the rear? If you run the Dana 70 as I suspect they have a quirk in that area.

Yeah, coined rims from Ford up through '83 or so. '93 Dodge rims are close but the rim doesn't fit over a Ford 10.25" rear center hub. Found that out the hard way once the new tires were mounted. Chevy rims just won't work on a Ford for some dumb reason.

Once you get the coined rims, keep two big acorn lug nuts in your glove box. Then use them to center up the wheels before installing the washer style lug nuts to 105 ftlbs.

I also thought one side of the Dana 70 had left handed threads when new.

Snapped my favorite socket extension a few years ago trying to "loosen" the rear wheel before the penny finally dropped on that one. Clockwise to undo the driver's side.

Yes Jamie is right on the left handed studs. It's the drivers side wheel, it was an old theory that the lugs could loosen themselves so Dodge and Ford put the left hand threaded studs on them.

And it's not really that hard to do the machine work on your hub centric wheels so they will work with acorn style lugs in a "coined" pattern on your bump. There are few folks who will do the machine work for you due to the liability. There a few tech articles on the internet on how to do this-google is your friend as I've crashed computers that had the bookmark way...since then. I do still have the bevel drill for the machine work, (believe it is a 60% bevel on the acorn process) if your interested in it.
I know because I did it to my Alcoa's, (you'll never find a coined set of Alcoa's-they were never made-unless someone did the machine work on them as I did).

always nice to rehash updates on dually topics imho
still have the original 16" split rims on mine. i do like the way th alternating coins "lock" into each other with that style wheel so i'm on the lookout for the '73 through '83 steel coins...

[MurrayPro92]

Good stuff!! thanks!! I feel like an idiot now. I thought my studs on the drivers side were severely rusted and not wanting to loosen but I found out they are left hand thread I forgot about those!

I had found a fleabay source for aftermarket made, (they actually had china stamped on them) coined rims in 16" size back in 2008. I bought two of them from him before he disappeared from the net. The two 16" rims I got from him where scratched up when they arrived-but true and really nice for the price.
Look harder guys and I believe you'll find another source, (as well as my source for the inserts used to make aluminum alcoa hub centric wheels into coined rims if you want flashy bling rims on your dually.

wow would never have guessed there would be aftermarkets for these. thanks for the info. will have to expand the search!

[basketcase0302]

You are quite welcome. Also recommend using several different search keywords like:
16" rim
16" dually rim
16" X * X 6.5" rim
Ford dually rim
Ford dually Alcoa rim
Ford dually hub centric rim

Here's one source guys, (also don't just limit your search to ebay):

And I found the link where I got the inserts from guys!
