New ball joints stiff knuckle

Working on a friends 2000 dodge 2500 4x4 and after installing a set of lower and upper ball joints, the knuckle is very hard to turn. I understand ky should have some sort of resistance but not this much. I did a set of ball joint on my 03 a while back and don't recall having this issue. Can anyone point me in the right direction?



Thanks

Pete
