Add grease zerk to axle or not?
Just finished repacking all the hubs and noticed that there was a threaded hole at the end of the spindle and a small hole just inside the lip for the inner seal. I presume this is one of those easy ...

I doubt you'll hurt anything adding grease unless you blow it out the seal in back. Obviously, that wouldn't be good. Given the fact they are designed to allow pumping grease into, and through the hub, adding a little in a pinch won't hurt, just doubt it will be as effective as checking and packing directly as you did. I used my super lube feature for three years and it does sorta work, but it's a lot of grease and a lot of pumping. I have also opted for the direct method from here on out.
