Binding & hard steering is generally in the kingpins. Don,t trust these lube shops. Jack up the front end & take a grease gun & make shure grease goes through all 4 fittings. Move the wheels back & forth & grease them again. They should be easy to turn back & forth through the total travel. Looseness is generally in the steering gear box. Have someone move the steering gear back & forth & watch for looseness in the gear & rest of the linkage.
