Front axle seal

[JBUCKLEY]

Sorry posting a second time on correct forum page.
I have a 2007 2500 4x4, I have replaced the passenger side front axle seal twice, continued to leak, so I bought a new axle & seal, installed, and it started leaking again after a few miles, any suggestions?

What brand seal are you using?

There are two sides to a seal, the one that seals the rotating axle, which is where leaks usually happen, but also the one that seals against the axle housing. Inspect that for wear, pitting poor seal. Also inspect the axle for any kind of up and down or side to side movement where it comes through the bearing. If the bearing is going and allows the axle to move the seal won't last long.
