Stuck Lug Nuts

Hi All, the shop that did my brakes must have put about 300 pounds of torque on each of the lug nuts. Has anyone placed heat on the lug nits to try and remove?

I did use a hole saw for the back left wheel and chipped away the mushroom piece once it snapped but hoping for a quicker way to accomplish this.

Thanks in advance for the assistance.

On more than one occasion I've taken my car back to a shop for them to loosen the lug nuts they put on without a torque stick. Neither were happy to do it but they did it.

I've also taken my car in to have the tires rotated for the express purpose of loosening stuck lug nuts.

Both are a lot less work than trying to do it without power tools.

Tire shop broke one trying to take it off. I am tempted to bring it back to the shop but the brakes were done a few years ago.

I have had this issue and no one but me torques up the lug nuts. Some sort of galling or corrosion can make the nuts hard to remove sometimes. Never to the point of breaking a lug nut though. As these are aluminum nuts it's not a great idea to lest a shop monster them on.

I think there is a Porsche TSB suggesting using a moly lube on aluminum lugnuts. I have always left them dry and jumped on the breaker bar if one got stiff.

IMO do not try to bust them loose with an impact if they are stuck.

Use a 1/2 inch breaker bar, a 6" extension and a 6 point 19mm socket. Apply foot pressure if necessary and break free all 5 lug nuts, lube, and retighten to 100Ft Lbs with a cheap torque wrench.

The shops charge extra to check with a torque wrench. Ha Ha...

Also improperly torqued lugnuts can lead to warped rotors or hubs or wheels, so always check torque after a shop has had the car...

if someone is using an impact wrench on your 944's lug nuts, relieve them of the tool and repeatedly apply the tool to their skull.

Agreed!
There is a special (soft) socket for these lug nuts.

I'll hold them, you apply the tool...

+1 get the soft socket and use a torque wrench. The soft socket is the most often used special tool in my toolbox.

I bought mine from our forum host Pelican many years ago. I went for a good quality tool as I use it often but there are cheaper available. Mine is by Sir Tools made in the USA 19mm soft lug deep impact socket.
