What you have just experienced is why Mercedes issued a TSB in the '90s requiring that the extended length lugs (greater than 80 mm total length) used on 107/126 models be replaced with "short" lugs (50-62 mm) like those used on later 124/201s. Few shops except dealers (and hardly all of them) ever informed their customers that this was a serious problem.
For 30+ years I have wiped the threads of the lugs with paraffin EVERY time they were loosened and tightened. That has virtually eliminated corrosion caused thread seizure. Whenever a shop tightens the lugs as soon as I get home I loosen them, apply paraffin, and re-tighten to spec. DO NOT ALLOW THE PARAFFIN TO TOUCH EITHER THE LUG OR WHEEL SEAT. Haven't had a lug seize since I started using this technique. A long extension is MUCH more likely to shear the lug that a rattle gun. Marshall -- Marshall Booth Ph.D. Ass't Prof. (ret.)
