    OT: Power steering '99 Yukon/Denali

    Sorry for posting here, but have tried a couple of my other car websites and have gotten some truly bizarre opinions.

    99 GMC Denali (same as Yukon) 75K miles, seems to get a little more power steering in the middle of some turns. Fluid isn't/hasn't been low. Doesn't chatter or act strange at idle or when sitting still turning wheel with engine running. It's almost like the power steering just gives it a little more suddenly in a turn at highway speeds resulting in the wheel turning a little sharper. Considered throwing a new pump at it and see if it fixes it, given the expense of the box and complexity of changing it. Don't feel like getting robbed in a dealership for a repair on a vehicle that's lookin' for a new home, but want it fixed before selling.

    I have a 98 Yukon that had this problem. The fix was replacement of the steering wheel rotation sensor.

        I had the dealer do the work. My undertsanding is that it is located in the steering column somewhere.

          Norris,
          The steering wheel sensor is located between the upper and lower steering shafts and changing it requires locking the steering shaft in place and disabling the supplemental inflatible restraint (SIR) system (airbag).
          Diagnosing whether you really need this sensor or if there's something else going on requires special equipment like a scan tool (tech 2)to read the values of the sensor as you turn the wheel and/or power steering system tester to read line pressures. Otherwise you're just guessing if you go ahead and change the sensor.
