I can turn the road wheel by hand easily when the pitman arm is disconnected and the joints are greased and dont look that old but as regards the binding on the steering wheel, that may be down to the piece of [Edited by Moparts - Family Friendly Site - Keep it clean] steering wheel someone has fitted and i think the parts underneath it are wrong because i had to make a collar to space the boss so it wouldn't bind on the outer section of the column but the downside of that is the centre nut doesn't go on all the way. I thing the press on ring for the horn is too deep for this wheel. However, i dont think it's the problem on the steering box other than it's a touch tight on the steering wheel itself but when it's all connected up, i cant turn the steering by the road wheel when it's jacked up.
