have you tried switching left front to right on your tires to see if it's a tire pull?

Auto 4W or regular 4W.
What transfer case?
Are you trying to drive it in 4W on dry payment?
Are all 4 tires a matched set?

What or what kind of trans axel did you change?

i had a ford 4x4 and i sold it back to the guy i bought it from anyway he took it to pep boys and had ball joints put in they said they test drove it yah rite you couldn't keep it on the road he brung it back to me and i checked it out and the gear box was broken from the frame. he had it welded and there still driving it. but told him why the hell did you take it to pep boys.
