people tell me that yes, the pinion shaft seal is replaceable merely by removing
the yoke. The guy in the Parts Dept. at my local Ford dealer doesn't
recommend that I do it, he talks about crush-bearings and tolerances and such
+ the nut that holds the yoke on is officially a single-use item and should be
replaced with a brand-new one (still available from Ford, I seem to recall about
$15 but it's been over a year since I talked to the guy).
Another ex-Ford mechanic I spoke with says the nuts can be re-used and that
the entire process isn't too awful complicated BUT you have to pay special
attention to clearances & tolerances & torque and such. If/when I do this, I'm
gonna make sure that guy is pretty dang close at hand....

years ago, i got the seal and put it in place, and tightened the nut down, and realized very quickly that the seal wasn't in far enuff. i figured shops had special tools and equip and training to do this procedure. i took her to a nearby shop, and the guy let me watch. all he did was find something cylindrical that fit the approx size of the seal, and hammered it in kinda like a freeze plug.

pinion seals are a piece of cake. dump trucks hammer them out all the time so i get to change 2 or 3 a month.just make sure you drive it in straight and don't distort it.now axle hub seals are a whole other matter

I've been reading up on this also. I am pretty sure i can do it, along with a friend of mine, in a matter of a day. The only problem is that I am comfortable doing brakes, minor engine, and minor transmission stuff (replacing transmission lines and that kind of stuff) and also a bit of coolant . BUT I do not have the confidence, nor am I comfortable messing with things that affect the core components of the vehicle.
DIFFERENTIAL OVERHAUL
A differential overhaul is a complex, highly technical, and time-consuming operation, which requires a great many tools, extensive knowledge of the unit and the way it works, and a high degree of mechanical experience and ability. It is highly advisable that the amateur mechanic not attempt any work on the differential unit.
I'll take that advice, and paint my rims instead haha!

Uhh....
- Raise and safely support the vehicle with jackstands under the frame rails. Allow the axle to drop to rebound position for working clearance.
- Remove the rear wheels and brake drums. No drag must be present on the axle.
- Mark the companion flanges and U-joints for correct reinstallation position.
- Remove the driveshaft.
- Using an inch pound torque wrench and socket on the pinion yoke nut measure the amount of torque needed to maintain differential rotation through several clockwise revolutions. Record the measurement.
- Use a suitable tool to hold the companion flange. Remove the pinion nut.
- Place a drain pan under the differential, clean the area around the seal, and mark the yoke-to-pinion relation.
- Use a 2-jawed puller to remove the pinion.
- Remove the seal with a small prybar.
