Question about the rear axles and seals

I have grease centrifugally leaking out of the seal on the driver's rear corner. I had, last week, the same problem on the other side, but it went away after the first clean-up (at about 120 miles or so from new).
I don't think there's a torque difference between right and left, since I put them on with an air tool. Both cotter pins are correctly placed and tight; neither shows undue wear.
The discs are on the CB Performance Wide-5 hubs, bolted tightly together without any flaws in the materiel, with the short axles appearing to be in place and holding fine.
Question is, why would the grease still be leaking after the initial couple hundred miles? The only thing I can think of is that I over-packed the bearing and the liquified overflow is what's coming out the center of the hub.
I'm contemplating going back to basics with Muir's book to see if I overlooked something obvious.
Anyone want to take a stab at it?

Thanks, Larry -- I'll have it licked by 9:00 tomorrow morning. Thanks for the link!

Cory; the only thing I can think of is the axle seal; obviously you installed new ones; are they properly seated? When we were fixing up Jjr's dune buggy we replaced the boots and the brakes but didn't replace the seals. Jjr had to disassemble both brake drums after he'd installed all new brakes to install new axle seals. Sure enough, they stopped leaking.

Check the mission accomplished block on the leaky axles. Simple fix was to take the cotter pins out, apply one 36mm socket on a torque bar and tighten the nuts.
Believe it or not, they were a quarter-turn loose. Barely more than hand-tight.

Me, to the Ace Wrench: "Did you tighten these before you put the cotter pins in?"
Wrench: "Nope. I thought you did."

Duh. I'm a dolt. Problem's fixed, though! I took off from the garage when we were done with that, a valve adjustment and a carb reset ... and promptly ran out of gas about a mile and a half later. New problem: Need a fuel gauge or a wooden dowel.
I was probably the only person in history to laugh hysterically about running out of gas. People must have thought I was a looney.

If thats the only issue that comes up from building a car from scratch I think you have done a great job. Its amazing how many little things can pop up, even if you thought you have done everything right. A few years back I built a Kelmark kit car and had about 2 miles on it (I got gas), when a guy called from North Carolina and said he was flying up to Massachusetts, taking a bus, then a cab to my house and was going to drive the car back. I told him I didn't think that was too smart and said I would make him sign a release absolving me from anything that may happen on the way. I told him it was a hand assembled vehicle and hasn't even really been more than test driven. He insisted it would be fine and had no problem signing the release. Sure enough he shows up with a small overnight bag, hands me the money, jumps in the car and drives off, not even attaching a plate.
A couple of days later I get a call from him. Appaarently he drove straight through to DC, stayed overnight, then made it about 2 blocks away from his house the next day before getting pulled over by the police. He said a windshield wiper flew off and that a heater box hose loosened up, but that was it the whole trip.
Crazy guy!
