I have a 1999 E300 TD Elegance - I had a problem a short while ago when one of the wheel bolts holding my N/S front wheel on snapped when it was being removed. To cut a long story short the wheel had to be cut off and replaced, according to the garage (local not MB) this is a known problem and the new bolt they had to purchase had a shorter neck than the existing bolts to prevent this problem. My question is : Should I replace all the other bolts (would there be any chance of MB doing this FOC?) or should I just remove them once a year say, grease them up and put them back on?Thanks in advance for any advice.....RgdsDave J.
