Ron. I hope Mr. Bayer read it. I'm sure your 240D was built in Germany. Like I said in an earlier thread I was a GM mechanic in the 60's and in my shop I was the only one that did differentials and standard transmissions. Probably the most important setting is the pinion depth. On new gears a number that is etched on the gear tells you the amount to shim it to get proper depth. Then the backlash and bearing pre-load need to be correct too. All this is very critical and it's easy to have a slight noise, so I'm not blaming ZF gear company for the slight noise I have. My local MB shop foreman hears it and when he gets permission from Mercedes he will change it out. I doesn't really bother me, but after you write the big check for one of these you want it right!!
