hmm, why would the engine mounts grind?

This is my 2nd swap I've done.... Never had that problem wtih the first one...... Just curious....

I really prefer not to rip open a perfectly good boot just to check...... If anything, if it's the axles, I'll just get new ones this time...

anyone else think it'st he axles? sorta weird that they would only make a sound when turning HARD left/right though...
