Adding a grease fitting to slip yoke

This may be a dumb question, but I'll throw it out there anyway. Can you drill, tap and install a grease fitting to the slip yoke with out throwing the balance of the driveshaft off.
Thanks

there wouldn't be enough difference with drilling and fitting to notice

only drawback would be if over greased would collect in rubber bellow

I had an aftermarket (Tom Wood) driveshaft in my last truck. It had a grease fitting as well as the rubber boot.

The driveshaft would get a bit of grease every 6 months or so. This worked well and I never had any problems with that driveshaft even after 120K miles of service.

wouldn't the zerk only feed one or two of the splines on the slipyoke? I've always just taken it apart and applied grease to the male side of the shaft splines.

You can always take the "over-engineered" approach and install two fittings opposite each other, and then put half a stroke of grease in each fitting every time you change oil.

I believe that this is correct. Shafts that have a grease fitting also have a groove around that shaft to lets the grease travel to the others channels.
