I've put new drums and shoes on my 2001 Mazda B4000 in the last 5 months. I recently had someone try to steal my alloy rims and in the process they broke the keyed wheel stud. I am now trying to get the drum off so I can replace the broken stud. Problem I am having is the drum appears to be on very tight despite my loosenin the adjusters and using penetrant to loosen. Any idea on what I can do to remove this drum?
