Front Axle Seal Leak
If your front seal(s) leak after front end work waiting is the best thing you can do.
If the u-joint isn't supported in the stock position when the rotor is removed the seal gets deformed, fluid gets by and trapped in the axle tube.
When the axle is back in the normal position the seal will reseal but is still takes a long time for the oil that got by it to leak out, sometimes at least 500 miles.
You can speed up the drainage by parking the truck tilted toward the leak.
Don't overfill the differential, 3/4" below the bottom of the fill plug is spec.
Anything more and it's guaranteed to leak.
