How to Replace the Power Steering Hose on a Chevy 350
A 350 Chevrolet's power steering system is a hydraulically controlled linkage-type system which consists of a power steering pump, a power cylinder, a control valve, and connecting fluid lines. Over time, the lines which extend from the back of the power steering pump to the control valve can corrode and crack, resulting in leaks and an insufficient supply of power steering fluid. A low power steering fluid supply can cause jerky or hard steering and various steering and suspension noises. Thankfully, replacing the power steering hoses on a Chevy 350 is a straightforward process that can be completed in less than one hour.

Pour power steering fluid into the pump through the dipstick tube, and periodically check the fluid level by inserting the dipstick into the pump and then withdrawing the dipstick and reading the marks which have been stamped into the tip of the dipstick. Fluid should be added until the fluid reaches the "Full" mark on the dipstick. Start the engine and turn the steering wheel back and forth to bleed any air out of the system. Recheck the fluid level and add fluid if necessary.
