Replacing oil seal in axel tube

I have a 1987 full size blazer with 4wd manual locking hubs. I was leaking fluid out of the passengers axel tube on the front. I took the wheel off etc and got the axel out. There is no bearing nor seal at the
outer end of the axel tube. It looks like the seal is in the tube at the diferential end.
Do I have to take the differential apart to replace these seals?
The passenger side is the short axel side. The drivers side, if the same, would put the seal about 4 feet from the wheel. Again I'm thinking I have to take the differential apart to get to the seals.
Anyone done this before to give me some guidence and or reasurance.
Thanks in advance.
Mark

Are the seals for the front axel changed from inside the differential?
Now that we have both axels out it looks like the only way to get to the seals is from the inside of the differential.
Dave have you done this before?
Thanks

Mark, you have to remove both of the axles, then the front cover, remove the 4 large bolts holding the diff side bearing caps and remove the caps keeping in mind they must be replaced in their original position. Using a pry bar gently ease the diff carrier out of the housing being careful not to damage it or the gasket surface on the housing with the pry bar. Now you can pry the old seal's from the housing and replace them, careful not to damage the pinion while you're in there as it will be slightly in your way.
Good luck: Dave.
