Ahhhh. Hmmmmm. Have you removed the diff cover? If not, remove that so you can see what the heck is going on. Maybe the shaft isn't perfectly lined up with the splines to allow it to slide in (although I am sure you twisted it around a zillion times already), but that will allow you to see whats appening anyway.

 

now i got the axles installed i noticed there is a bearing that the half shaft goes into and i noticed mine is bad..what is it called and how do you get it out and a new one in place?

 

this place has all the front end components. here's your bushing, bearing, and seal.
