the pinion is the part where the power comes into the diff to be distributed to the wheels. the driveshaft attaches to it. resealing that might not be too bad but will require removal of the driveshaft. again, a little seepage there is nothing to get excited about. a lot of oil may also mean a bad pinion bearing too, but that is VERY unlikely with the rugged benz diff.

good work so far.

as yogi berra used to say "you can tell a lot just by looking".
