Try to get some Penetrating oil or Coke (drink not powder ) onto the studs where they enter the hub. I know that is difficult with the wheels on but maybe through the centre hole or from behind. Leave it to soak in for a while. Get a metal rod or bar onto the head of the wheel Stud/Bolt and strike it firmly a few times with a large mallet in the direction of the hub. Be carefull not to damage the wheel (or your fingers ).
Use a long socket bar with a pipe extension to torque the Bolt out. Good luck

I had to stand on the wrench. I weigh 220ish, but still had to bounce. They look stretched.
Remember what my car's PO didn't know... 70-80 NM torque! |

the correct torque is about 82 ft pounds i believe.

CRC makes a product called Blaster. It's the best stuff I've found so far.
Any penetrating oil will work though, the trick is getting it forced into the area. Airasol type spray cans will work about the best. Use a LOT of it. DONT be stingy. Squirt the hell out of it, go back the next day and hit em again....If you have several days, Keep hitting it with the stuff and waiting. Time is you're best friend when it comes to soaking rusted bolts. Wheel studs are pretty beefy though, being that it's a wheel stud and not likely to snap off, I'd soak em once, come back the next day with a genuine impact socket which is EXACTLY the correct size or is a very snug fit. Use a breaker bar and a long pole to slip over the top of the bar. Don't try to muscle it, you want to snap it. Get everything on there and ready and give her a good yank. It'll probably snap loose, not off. Good luck Wayne |

"Snap"?
Mine was TIGHT for about a whole 1/4 turn! There was no "snapping" involved. It was like, bounce (little movement), bounce (little more), boune (little more), bounce (swing free!). |

anybody got an impact driver?
I love the simple hammer strike impact tool. get one in 1/2 " drive and pop a perfect fit impact socket on and WHACK! two or three hits is usually all it takes. much simpler than jumping on an extention. also available are the 12V electric impact drivers, they work quite nicely a little slow compared to the real air powered buggers, but they can be had at any auto parts store for around 40.00 and they usually come with an assortment of impact sockets for most (including the 17MM MB socket!) cars. They also have about a 12 foot cord so easy to reach all wheels from the front or rear cig socket.
