its not as important to use non-synthen with the tru-tracs as it is with the eaton's- which are still a clutch style assembly. the clutches in the eatons will burn up if a synthetic oil is used as they will 'slip' with the lessened frictional coeffiecient provided by the synthetic oils. For a tru-trac you should be safe running almost any 'good' rear end lube.

Its my understanding that the Ford fluid is a full synthetic. The clutches are the reason a friction modifier is used which works well with any synthetic. I've been using Amsoil synthetic in my rear end for the last 5 years.
Take a look in your F-150 owner's manual: Motorcraft SAE 75W-140 Synthetic Rear Axle Lubricant. So much for that theory

All synthetics are good oils but one thing that Amsoil does better is they have lower volatility than anybody else. So less goes up in the air and for engine less in the intercooler. Here's the latest from Amsoil for heavy towing, off road and racing. Don't sell it, just use it.

Is it possible that it was overfilled?
Pull the factory fill plug on the side of the housing and check the level there, I have used several aftermarket housing covers in racing use and at times have had the x-tra capacity covers cause problems when filled to full capacity. May or may not fix the axle seal issue, worth a shot though.
