I am so happy for now. I looked at the Benz CD to see how to replace this pinion oil seal. Guess what it explains the whole procedure so nicely
AND YOU NOT HAVE TO REMOVE THE THE WHOLE DRIVE SHAFT
( Hayes manual is a little vague about it and says you have to remove the driveshaft)
All you need to do is loosen the a check nut by 2 turn in the front near the transmission, then loosen the nuts on the center bearing clamp, then unflange the shaft at the end( 3 bolts only) towards the differential, now push back the shaft towards the front make sure you tie the shaft with a wire to some heavy solid part on the bottom of the body this way you dont drop the shaft by mistake.
Now after pushing back the shaft anf sliding it off center you have room to remove the nut that holds the flang using the special tool. Once the nut is out, use a puller to pull the flange out. Now you see the pinion oil seal. Pry it out with a screw driver and make sure no portion on it is stuck to the seat. Put the new seal in 9 use the diff oil to lubricate the new seal. Then push it in by slow tapping on it using a big size socket. Push it in until it stops.
Then just put all things back in reverse order. For a home mechanic only problem is no access to lift and the special tool needed to remove the flange nut. But at least you know how easy it is for someone with average mechanical skills and right tools.
Thanks I am VERY HAPPY NOW.
