Well, the pinion seal does not leak (I was informed that it 'sweats a little'). Apparently, there is nothing wrong with the suspension (although front still rides 2 inches higher than other 190s, and the rear still squeeks a little despite a bath in the lubricating oil). I politely refused an offer of fixing the vacuum cutoff valve for $300-$400 plus $86 in parts (just ordered a new one from Germanstar for $26-thanx Ron and Manny!). <br> Well, now off we go to install a new AC comp ($240 remanned)!
