Leaky Axle seal in front.. ignore it or ?

I noticed my mom's 4.0 the front axle is starting to leak gear oil on the short shaft side or drivers side.. Its basically covering the knuckle.. But I think its a super slow leak as when I checked the level after our double 1500 mile trips it was the same.

So what is the process of replacing these seals.. Is it hard ? or should I just ignore it ?

Not that hard, if you're mechanically inclined. Changing them involves:

- Taking the wheels off, pulling axles out (need a 12-point 13mm socket to undo the bearing hub bolts)
- Taking the diff carrier out
- Replacing the seals
- Putting all back together.

If you're not shy of doing all the above, here's a good writeup:

Don't make it difficult... plus a better write up with pics is in our FAQs page. You guys should read through that sometime.

Thirty mins tops to replace it.

Well I've replaced her cv shafts not too long ago actually its been maybe 5 months.. So im familer with how to take all that apart.. Now the differential if I remove that big gear like in the link it isn't going to cause any problems where I need a special tool to calibrate anything ? It just unbolts and pulls out and then bolts back in

Yep, pretty much. Just take care to put the bearings and bearing caps where they were originally (and how they were, cap alignment does matter), + torque cap bolts to spec.
