Will the hydro-boost on A 1997 Dodge 2500 4X4 affect power steering?

Yes, the hydro-boost on a 1997 Dodge 2500 4x4 directly affects the power steering. The hydro-boost system uses hydraulic pressure from the brake system to assist the power steering pump. If there's a problem with the hydro-boost system (leaks, faulty components), it will significantly reduce or completely eliminate power steering assist. Essentially, the hydro-boost *is* a crucial part of the power steering system on that vehicle, not a separate entity.
