Those axle seals will not work on a standard (not a Jeep TJ) Dana 44 for two reasons:

1. The knuckle's steering axis does not match up with the u-joint. Hence, when the knuckle turns the axle shaft moves front to back in the housing.

2. Dana 44s position the u-joint very close to the inner C, so close that there would be no room for those special seals. Dana 30 knuckles are very different in this respect.

The only reason you might find them referenced as fitting a Dana 44 is for the TJ, the "Rubicon" Dana 44 front housing is built like a Dana 30 with regard to the knuckles.
