2004 GMC Yukon SLT Flex Fuel. Vortec V8 5.3L. The steering has difficulty turning to right, but not left. There is also a whining noise when either hitting the accelerator or attempting to turn right. When accelerating, the steering is somewhat easier to the right, but still hear whining noise. Best way to describe the noise is like a dentist's drill.
I replaced the power steering pump, bought new from OReilly auto parts. Whining noise did not change, and still did not correct the steering problem to the right or the noise issue.
It is equipped with hydraulic boost breaking system connected to the power steering pump. I did the break test during engine off and restart and seems to be okay.
The noise is obnoxious and would like my steering to operate normally. When I replaced the PS pump, I bled the lines by turning wheel many times without improvement. Fluid levels normal with power steering fluid.
Does the whole system need to be flushed including the hydro boost or is this a totally different issue?
have the same problem?
