Not sure how to change the seal but the fluid can be changed only by removing the diff cover. Then cleaning all the oil out and resealing the diff cover.

To do axle seals on the front you basically take everything apart. If you did the shaft ujoints you are more than halfway there. Driver seal is right net to the pumpkin and passenger is just to the right of the CAD. Past removing shafts you will also need to take out the CAD shift fork and intermediate shaft, drop the carrier. Knock the old out and pull/press the new in. There are a lot of write ups around. Google D30 axle seal replacement.

So it would be better to do it before?

Center axle disconnect. The passenger side axle is 2 pieces. A vacuum operated "fork" slides a collar over an intermediate shaft to engage 4x4. This is why you don't have hubs to lock...

Get a couple of each seal...I tore the 1st ones up trying to get them back in...I found it easiest to take a piece of all thread and some washers and nuts and make a tool to insert them... you can see what I am talking about on the you tube. Good luck!
