Installing Zerk fitting for Greasing Front Hubs?

Hello,
I thought about doing this a while back and I thought someone on here had done a right up about drilling, tapping and installing a grease fitting to shoot new grease into their front hubs?
I did some searches and can't find it anymore?
Just wondering how I should measure to do this?
Where do I want the grease fitting to be?
Anyone ever think about doing this?
I'm just lazy when it comes to servicing these Great Googley MoogleyGreat Googley MoogleyGreat Googley MoogleyGreat Googley Moogley front bearings and hubs all the time. I use good grease, tighten to spec and it seems I've gone through two sets of bearings in three years on each front wheel.
Thanks for any input.

With the way the wheels are snug to the hub, I would think it would make rotating tires a PIA.

Well, yes it would but I would rather remove a zerk fitting to change a tire instead of redoing an entire hub because the grease and bearings crapped out.
I'm sure the post I saw addressed this issue and it looked like the zerk fitting was somewhere infront of the wheel when it was one the hub.

Something i wrong, though recomended to do a hub pack every year or so, (or after the hubs have been submerged in water) there are trucks out there with 10+ years on a hub repack.
Show us your failed bearings and walk us though your procedure to see if we can spot the issue.

In all honesty, I guess i'm just paranoid that next trip I make I'll be going down the highway when one starts to go. I have become rather familiar with the assembly/disassembly of the front wheel hubs. I used the manual and this forum to make sure I did it to the best of my knowledge last time. I know one time I did it I did not use a wheel bearing grease and not enough of it because they went pretty quick. The next time I think the damage had been done to some parts in side and I did not torque enough and one went bad again.
In all fairness, I drove 150 miles approx. Sunday and I got out to check the hubs temp with my hand after doing 70 mph for some time, barely warm.
I thought, maybe I did this right this time.
Just really thought it would be nice to shoot some grease in there after a good water/mud run.

I'm not sure how well you can pack the bearings by injecting grease into the hub area.

Even if you could I think the new grease would tend to flow mostly to the outer bearing because of the inner seal

I agree. If they are greased well during installation, they should be fine.

You should have extra grease between the 2 bearings so when the hub heats the centrifugal force will make it flow at least to the outer bearing and maybe the inner

Agreed. Packing the entire hub full of grease isn't going to accomplish anything unless you're running closed knuckles On open knuckles the hubs themselves just need a light coating of grease. You get'em too full and you won't be able to twist'em when it gets cold out.
Unless you're doing a lot of water crossings the hubs and wheel bearing only need to be greased every 20-25,000 miles depending on use. I think you're trying to fix a problem that doesn't exist.

Warn Hubs will not honour warranty if hubs are greased, they come packed with enough from the factory. To much grease will cause the hubs locking ability to hang up, and not be fully engaged, then when you put the fuel to it, it breaks When I service front end, Wheel bearings get packed, hub components just a light coating of white grease

also if your pumping grease in there and you pump too much in and blow the seal out now you have grease on your brakes. or if you have too much in there and it starts to seep out going down the road now you have grease on your brakes and all over everything.
