My neighbor used to repair vehicles for a painter friend. Brought an E350 cargo van home to put Kingpins in it and we found that what it needed was Axle-to-Crossmember Bushings instead. Solved its loose steering problem. When I replaced ours, change wasn't night-and-day but notable.
All we ever replaced on our '83 steering and front suspension was rubber parts. Adjusted toe, but never took it to an alignment shop.
The REAR springs were sagged and we separated the spring pack and added a "repair leaf" to each side. That got rid of a lot of sway and that's important with Ford's swing-axle (Twin-I-Beam) suspension.
As repaired, the 24-ft '83 with 158" WB drove better than our 2002 with upped Caster plus a track bar and upgraded front/rear sway bars.
