Reminds me of the time I was going to toss on the snow tires and wheels on Gwen's Mercedes.... A buddy had given me the set of tires already mounted on wheels. MBZ use BOLTs rather than studs and nuts...
SO I jack it up - grab the 1/2" air torque wrench... zip zap -- wheels off -- new wheels on.... time to back it out of the garage. IT WON'T BUDGE.... WTF?!?!? Call 1-800-nobody cares (Mercedes hot line) to see if I've tripped some anti theft device... NOPE....
Only thing that's changed is the wheels and tires -- back up in the air -- going to check the fronts for rotation --- nope - won't budge - not good.... Go get the air wrench -- bolts won't even back out --- max torque.... barely turning out... OH OH.... NOT GOOD.... ALL STOP. Call MBZ on Monday AM -- and a rollback - it goes to MBZ where they must now order all new "hubs" from GERMANY....
Seems that I just used the same wheel bolts from the factory wheels -- the "free" wheels used shorter pads and had shorter bolts -- which my buddy failed to give me not knowing any better (either did I!) -- thus allowing the bolts to go all the way into a back pad -- which mushroomed the bolt - and now to get 'em off you tear all the threads out of the hubs....
Can't remember if it was 5 or 10 grand... but Gwen reminds me all the time about it.
