Model A Hard to Steer

[50Trucking]

I bought a 28 Tudor that had been sitting since 2004. I have been working on it and have brought it back except for the steering. I have replaced all the grease fittings with Zerk fittings and greased everything but the wheel is still hard to turn even when moving. What should I do to run down what is causing this and how do I fix it. I can't believe these light cars were this hard to steer.
