A jack and a pair of axle stands is all you need. PM sent

Upon thinking about it further I don't think you need to remove the ABS sensors since they are in the hub and you are pulling that whole assembly, including the axle, out a few inches. I just replaced a rear diff on my second 99 and I did not pull out any ABS sensors. Didn't even remove the calipers from the hubs however you will have to do that if fitting the used disc to be pounded on.

To remove the diff you obviously have to remove the half shafts on both sides. To do that the hubs need to be pulled out at least far enough that they pull out of the diff. That involves pulling the ABS sensor out of its hole, removing the 4 bolts that hold the hub in place and the theory is that you then pull it out. However, as it has been there for the best part of 20 years simply pulling it out is unlikely to be successful. One way of doing it is to slacken the bolts and then hit the heads of the bolts to knock it out. That may work but the chances of catching the CV joint boot and splitting that is pretty high. The usual method is to put an old brake disc on back to front, bolt it up tight and bash it with a club hammer.

On the transfer case, if you just undo the 6 bolts the cover will come off with the output flange and viscous coupling. As the seal is behind the flange, you still won't be able to change the seal. The seal can be changed with just the flange taken off as it pushes in from outside. It's in RAVE, Section 41, Repair, Page 3.

I see what you are saying.. Thanks for the tip!

You do. The ABS sensors are in the outer swivel and the hub has a sleeve around it with a hole in it that the ABS sensor pokes through. If you were to pull the hub out without taking the sensor out, the end of it will be sheared off by the sleeve.

Different than the rear then. I did remove front hubs from a parts axle last year but couldn't remember the details, just that I used a puller.

 

[Richard_G]

What did you pull against? You can do it with a slide hammer on the wheel studs but I can't see how you would use a puller.

 

[Gordo51]

Took the axle nut off and pulled the hub off the axle shaft and housing. The other hub came off with a bit of tapping. Looked much less rusty so I think it might have been replaced at some time.

use antisieze compound on hub shoulder during assembly to keep them from rusting in place.

 

[Richard_G]

Ah, that would make sense but as he needs to take the hub and half shaft off, it wouldn't help much.

lots of penetrant lubricant and elbow grease.
