Alloy Duallies Stuck Together

They may be stuck at the hub where the whesls center onto it. I did the beating routine against the tires. I've heard of loosening the lug nuts then moving the coach and braking sharply. The lug holes are oversize, so any twisting applied by that maneuver will go to the hub.

2X4 against tire(do not hit the rim) and hit with big plastic "tire hammer" and

if they get them apart what is there to prevent this happening again?

when re-installing use plenty of anti-sieze or spray the hubs with a lot of white lithium grease before re-installing. And (your not going to like this) consider rotating tires maybe every other year or atleast pull the tires off and re-apply. (Might as well rotate if you pull them off) And try not to mix metals, alum with steel if at all possible. If that is the case. Be sure to check out the lug nut holes to make sure they are not "egg shaped".

And I knew nothing about this until reading your post and at same time was already on the phone with a guy that used to be a tire guy. I had no idea and don't really know if this will work or not. But he says it will. Sounds good, personally I would still get other opinions. This guy worked doing service calls on big truck tires for many years.

I suspect that a galvanic reaction has welded the parts together. I once built an electric inboard motor for a canoe. The aluminum tube welded itself to the stainless motor shaft so tight that I had to cut it off. A bit more complex than simple corrosion; dissimilar metals produce an electric charge that migrates the metal atoms together.

Normally you don't run alloy against alloy. because of this, normally the inside dual is steel.

you should be able to pull the cap nut off the outside on all studs, then loosen all the inner stud nuts a little at a time and the whole assembly will come off, even when stuck together.

or you can try.

removing all the cap nuts, then back off every other stud nut and force the 2 wheels apart. be careful, this might drive the inner stud into the hub.

I don't know the answer but These Guys will know the answer and will get it done.Ask for Tony

They are mobile too.
