I did not have to remove the pinion gear from the driveshaft. Is the drive shaft key located under the pinion gear on the driveshaft??? I just noticed one in the book A4606 and sure didnt see a place for it to go.

Did I miss something??????????

Yes, the driveshaft is tapered underneath the pinion gear. That taper has a key in it.

This a keyway similar to the axle/hub connection at the two rear wheels.

You may be able to remove the nut from the pinion gear and see the keyslot underneath.

You are wise to let sleeping dogs lie. The pinion removal is similar to removal of the rear hubs. The taper is self-locking - a "knock-off" or other tension/puller technique is required to remove the taper shaft from the taper hole in the pinion.

I used a piece of 1-1/4" pipe longer than the main shaft. Put the shaft down the pipe and allowed the pinon to catch up on the top end of the pipe.

Then I smartly rapped the whole assembly: pipe, shaft, pinon on the garage floor to do an "impact removal."

I might suggest putting a plug or other cushion to catch the driveshaft when it finally breaks loose. (so it doesn't pound a hole in your garage floor, or damage the spline where it attachs to the universal joint.)

Or (remembering here) leave the pinon nut in place but "loose." (To catch the shaft)
