Record by record

11 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it came back3
  • says it did not fix it3
  • result not stated7

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

  1. Manufacturer communication2003–2006 GMC YUKON DENALI ・ 2018-06-11(2 earlier editions of this document folded here)

    Power steering pump and line replacement procedure

    1. 1Fault

      • In rare cases there is a lack of steering assist when stopped or during parking lot type maneuvers.
      • The condition goes away or greatly improves once the vehicle begins to move or is above parking lot speeds.

    2. 2Finding the cause

      Possible causes

      • The concern can be aggravated by worn tires, low tire air pressure, low power steering pump pressures, and tires larger than stock size.

      Steps to confirm (in the document’s order)

      1. Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.
      2. To tell whether a 670 gear box is fitted, inspect the mounting bolts that attach the stub shaft housing; a 670 gear box has only 3 mounting bolts.

    3. 3Correction

      Repair

      1. If a C/K 1500 Series vehicle is equipped with a 670 gear box, replacing it with a 680 gear box may increase the customer satisfaction.
      2. When replacing a 670 gear box with a 680 gear box, replace the power steering gear, union fitting and both inlet O-ring seals.

      Parts

      • Parts (C/K 1500 series only): 88965542 Power Steering Gear, 26025709 Union Fitting, 26001594 Inlet O-ring Seal.

      Part numbers printed in the document

      The numbers are as the document prints them. The name and the replacing number are what the pages of GMPartsGiant, a reseller of genuine parts and not GM, state. Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

      Caution

      • For C/K 1500 series vehicles, if diagnostics did not lead to any repair, the concern is a normal operating characteristic.
      • If the stub shaft housing has no mounting bolts or has 4 bolts, do not proceed with this bulletin; the vehicle does not have a 670 gear box.
      • It is recommended in all cases that the proper tire size and the maximum tire pressure are set to the manufacturer's specification on the door placard, especially for the front tires.

    Power Steering Pump Whine Noise

    1. 1Fault

      • Owners may report a whine noise that normal diagnostics trace to the power steering pump, most commonly heard between idle and 2000 rpm.

    2. 2Finding the cause

      Possible causes
