Driveshaft & Pinion Question

[LeroyM]

What's the trick on getting theses two apart? Any help would be appreciated.

Thanks.

here are Tom Endy's words on removing the pinion from the drive shaft:

Pinion gear removal: (Photos P-4, P-5, P-6, P-7, P-8)
The pinion gear is removed from the drive shaft with a gear puller and a bearing puller. Place the drive shaft
in the pipe jaws of a vice. Remove the cotter pin from the drive shaft nut at the pinion end of the drive shaft.
Using a 15\16 hex socket, back the nut off about 1/4 of an inch (do not remove the nut completely). Place a
small bearing puller around the drive shaft behind the pinion gear (at the end of the threads on the pinion
gear sleeve) by sliding it on over the front end of the drive shaft. Using the gear puller, place the center point
of the puller in the détente at the pinion end of the drive shaft. Hook the arms of the gear puller around the
bearing puller and tighten until there is sufficient tension against the end of the drive shaft. Smartly tap the
end of the gear puller with a hammer. Alternately tighten the puller and tap the end until the pinion gear
comes loose from the taper on the end of the drive shaft. Remove the drive shaft nut and slide the pinion
gear off the end of the drive shaft. The rear bearing that is still attached to the pinion gear will have to be
removed with a bearing puller and a shop press.

there are photos and an excellent article on the entire rear axle here:

The operative words are smartly tap the gear puller with a hammer. I tried this, however, in my case it didn't release until I gave the the drive shaft a couple of good hard wacks with a hammer.

Thanks, good article.

Smartly tap is much the same as good hard whacks.
