This is going to sound stupid, but I am replacing some wheel hubs on a car and I can't get the wheel off. I pulled all 5 lugs, but it won't budge. I've tried prying, heating the rim up (27^ outside today), penetrating oil, and every type of force I can think of without damaging the rimm or other components. The lugs are straight and not holding it on.

So how the hell do I get this thing off?

yup, its the hub thats sticking on the rim.

Just keep heating it and stuff, and i had to use a sledge hammer once on my old car to get it off.

Smakc the hell out of it....Stick a rag around a long bar or something and then stuck the bar through the spokes (if applicable) and try to jar it loose that way too. Mistubishi'* are good for the wheels getting stuck on.

Ha ha your not the only one. My summer rims were stuck this year and really pissed me off.
I ended up with a sledge hammer and rapping the tire around and around.being careful of the rims.
it finnaly broke loose.

Make sure when you put them back on the car that you smear a lil anti seize on the contact area of the rotor and the wheel to prevent this from happening again.

just give it hell! i usally donky kick the bottom of the wheel! (if you dont know what a donky kick is, stand up, face away from the car, and proceed to kick the crap outta the itre) good luck!

I tried that and thought I was going to knock the car off the jack.

Does the service manual say something about rocking the car while on the ground? I think I remember glancing over that, but I'm at my parent'* place for the weekend and don't have them here.

I thought it sounded crazy since I've never had this problem, but I guess it'* somewhat common.

Use jack stands

just to change a tire? Naaaaaaaa
