Beating the rust

[lifetrddeath]

The old tow ball on my truck is way past its due, rusted like you wouldn't believe. The nut holding it in place won't budge. I've drowned it in WD-40 hoping to get it loose to no avail. I'm about to try using some good ol' Coca-Cola. Any other ideas using conventional man power tools?

liquid wrench usually out does wd 40. and try a cresant wrech on the ball to hold it and use a socket on the bottom. i had to do that on mine. it finally gave up and come off.

Try tightening it first and then loosening it after you spray it with penetrating oil. WD40 doesn't do the job. You can wang a breaker bar with a large hammer to work things loose.
