Mercedes CLS Locking wheel Nut

A very non productive day. I set out to renew the brake pads in my Mercedes CLS 320...it didn't go well !!

I've just had this exact problem on my CLS320, tyre fitter for the previous owner has buzzed all the nuts on to a ridiculous degree, it took all 16 stone of me on the end of a 3ft bar to crack the hex bolts loose so obviously the locking nut snapped just like yours. I've got hold of a new key but not sure how I'm going to get this locking nut out! I've got some reverse thread female stud extractors coming so hopefull they work...

@stevendcruze7395 I don't understand why mine were so tight, I put them on myself and I never overtighten them. If they needed to be so tight the car manufacturers would supply a longer wheelbrace. The best way to get them off is to split the outer ring with a good quality sharp steel chisel then use the stud extractor. Hope that helps.
