I've just done this on my 1998 whilst rebuilding the axle.
On mine, the studs were press fit, with splines to grip the holes in the axle casing - they were not difficult to drift out.
When inserting your new stud, try and align the splines on the stud to the original splines in the casing.
Most of mine just pulled in when I tightened the nuts up - I used a piece of tube so I could do the job with the diff out and see in the axle casing to make sure all was well.
One or two needed help with a hammer, but they all went in fine in the end.
