You have to be careful when you pull the axle out not to damage the seal. It's easy to mess up the seal if you just slam the thing back in. If you already had the axle and seal replaced before, then I would say the problem is the mechanic and not the axle.

Probably it's only going to leak a little bit, so don't worry too much. Just keep an eye on the trans fluid, and change it a lot.
