OP, I run into this pretty often after wheeling. Sometimes dirt/mud will get in that area and cause the seal to leak, and sometimes a clogged diff vent will cause pressure build up in the front diff, forcing a slight leak at an axle seal. Consider inspecting/cleaning the front diff vent, and using some brake clean spray to get into the area around the CV axle where it enters the housing at the seal. Clean it real well, and blow it dry with some compressed air if you have access to it. I have had my seal leak after almost every wheeling trip. I clean the affected area, clean off dirt/dust from the vent, and no more leaking.

, I gave up n took it in to a mechanics shop to get it fixed n now they telling me it's the axle that needs replacing, supposedly the autozone axles are crap so they are putting me on a different cv axle they said is better in quality. I'm starting to feel like I'm being put on that magic carpet ride..... But with all your guys' help I hopefully can get my issue taken care of. Btw I have a toytec
coilover lift. Mechanic also said if axle don't fix seal leak then it's the lift causing it,,, so you see now why it sounds like I'm being set up.... Or I feel that way myself... Just don't wanna be getting messed with n possibly ripped off
Repeated axle seal failures are typically due to a bad front diff output shaft bearing, which is what the CV axle rides on inside the diff. Most likely your bearing is bad. Check with ECGS on a search here and you will find the replacement bushings. Swap out the seals and bushings, install a NEW CV axle (The most recent one you have installed has probably already been damaged by the failed bearing) and you should be good to go.
