The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:LeakNoiseMisfire or rough idleVibration or shudder

Record by record

14 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

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.

Known issuesHydro-boost brake assist and power steering share one hydraulic supply (four campaigns)2

  1. Manufacturer communication2003–2006 GMC YUKON XL ・ 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.

      • Perform the "Power Steering System Test" found in SI and make any necessary repairs based on system diagnosis.

      Repair

      1. Dealers replace the hydro-boost relief valve.
      2. Dealers test the hydro-boost assembly for functional operation and replace it if it fails.

      Caution

      • An inoperative pump raises steering and braking effort but does not completely remove the ability to steer or slow the vehicle.

      This Preliminary Information communication provides information to the technician the steps needed to diagnose and repair the vehicles that may have unwanted or phantom phone calls. Technician will need to determine what type of call the customer is having that is unwanted. The vehicle may receive an incoming call just like any other phone. Typically the customer will hear the phone ringing in the vehicle. This scenario also includes incoming Bluetooth calls. One type of unwanted call can be made if the key pad is faulty the OnStar system will try to make a blue button call for shorted voltage in the circuits. The OnStar module could have an internal fault and produce a ″Phone Unavailable″ audio message also it may have a Diagnostic Trouble Code U1500 or B1000. Refer to diagnostics for the Diagnostic Trouble Code making sure to follow any applicable Bulletins or Preliminary Information sheets. A “Ready” or “OnStar ready” audio message heard while driving. In some cases it has been found that the customer is inadvertently pressing the ″push to talk″ button on the steering wheel controls. On rare occasions, other issues in the steering column or Steering Wheel Control system may induce this concern.

      Steps to confirm (in the document’s order)

      1. When diagnosing vibration, use the worksheet together with the Vibration Analysis - Road Testing procedure in the service information.
      2. Place the sensor where the vibration is felt: on the seat track for a seat complaint, on the steering column for a steering wheel complaint.
      3. Moving the sensor to other areas, look for the same Hz reading with the greatest amplitude.
      4. If a system balance was attempted and the vibration remains, check ring gear backlash at each tooth; readings should not vary more than 0.050 mm (0.002 in).
      5. Aluminum wheel/tire runout measured on the vehicle: maximum 0.030 in (.762 mm).
