You say you don't want to do it now, but poking a hole in the boot is asking for it to tear. You may be accelerating the failure. Besides, if the boot is intact, and there is no grease around it indicating a leak, it may not be a lubrication problem, just the axle wearing out. I would just get ready to replace it, IMHO.
The first time the boot cracked, it was a hard plastic like boot. Cracked right on the edge. The second time my wheel bearing seized and melted the boot off. I was going to put silicone or shoe goop, something tacky and flexible over the hole. I'm talking pin size.
