Leak!

I replaced all four ball joints a few weeks ago. The truck was on a little bit of a slope and some of the center differential fluid leaked out when I pulled the Drivers side axle. I thought what I had been seeing was left over from that but now it is clear from the amount I have seen in several different places it is leaking from the dust seal between the axle and the u joint. Is there a seal around the axle at the differential?

About how long of a job is that compared to ball joints? I would assume both drive shafts have to come out.

Balljoints are around six hours and front diff seals are about five hours. Both axles come out. Should probably do the hub seals while it's apart too.

I did the hub seals when I did the ball joints.

Will this take any special tools? Thanks again for the info.

There is a special tool to install the seals but if your careful you should be fine without it. Here's what it looks like.

Can any one give me a part number for the seal around the axle at the front differential? I have looked and not sure what I need.

Should I replace both sides?
What else should I do while I am there?
As long as I do not use the 4X4 and the the hubs are not locked, will it hurt if all of the fluid runs out? (2 quarts on hand just in case)
