Known issuesHydro-boost brake assist and power steering share one hydraulic supply (four campaigns)4

  1. Recall2006 GMC YUKON ・ 2005-05-10

    Power Steering Hose Fracture

    1. 1Fault

      • Under extreme steering maneuvers, such as turning the steering wheel fully left or right while braking, the hose may fracture and leak fluid; power steering assist would be lost and steering effort would increase.
      • On vehicles with hydro-boost power brakes it could also result in loss of power brake assist and increased braking effort; if the fluid sprays onto hot engine parts, an engine compartment fire could occur.
      • With the Hydroboost braking system, braking assist will be limited to the reserve power assist system; the braking systems on vehicles without Hydroboost are unaffected.

    2. 2Finding the cause

      Possible causes

      • The high pressure power-steering hose was manufactured with an incorrect compound, making it susceptible to high pressure failure at the elevated fluid temperatures and pressures that can occur during simultaneous braking and steering inputs.

      Steps to confirm (in the document’s order)

      1. Inspect and record the date code on the power steering pressure line; it is printed on the hose and repeated approximately every 6 inches (150 mm).
      2. Vehicles with the hydro-boost system have two hoses to inspect, others only one; the conduit may have to be removed to read the date code.
      3. The suspect date codes are 07135F-2 and 07145F-2; if the hose carries one of them, it must be replaced.

    3. 3Correction

      Repair

      1. If the date code is not one of the listed codes, replace the conduit if applicable; no further action is required.
      2. For Silverado/Tahoe/Sierra/Yukon/Escalade, hose replacement follows SI documents 756552 (Non Hydro-Boost Pressure line), 651043 (Power Steering Pump to Hydro-Boost Pressure line) and 651019 (Hydro-Boost to Steering Gear Pressure Line).

      Parts

      • Less than 10% of the involved vehicles will require hose replacement; if parts are required, the appropriate hose(s) are ordered from GMSPO.

      Caution

      • This bulletin is a revision to address hoses used to service 1991-2006 vehicles; dealers who ordered these hoses for service are identified in the attachment to the administrative message.
      • Vehicle eligibility should be confirmed through GMVIS before beginning recall repairs; not all vehicles within the breakpoints may be involved.

    Cause
    CERTAIN PASSENGER VEHICLES MAY HAVE BEEN BUILT WITH A POWER STEERING HOSE THAT IS NOT TO SPECIFICATION. UNDER EXTREME STEERING MANEUVERS, SUCH AS TURNING THE STEERING WHEEL FULLY TO THE LEFT OR RIGHT WHILE BRAKING, THE HOSE MAY FRACTURE AND LEAK FLUID.
    Remedy
    DEALERS WILL INSPECT THE POWER STEERING HOSE(S) FOR TWO SUSPECT DATE CODES AND REPLACE THEM IF REQUIRED. THE RECALL WILL BEGIN ON OCTOBER 14, 2005. OWNERS MAY CONTACT CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, ISUZU AT 1-800-255-6727, OR HUMMER AT 1-800-732-5493.
    Consequence
    IF THIS WERE TO OCCUR, POWER STEERING ASSIST WOULD BE LOST AND INCREASED STEERING EFFORT WOULD BE REQUIRED. ON VEHICLES EQUIPPED WITH HYDRO-BOOST POWER BRAKES, IT COULD ALSO RESULT IN LOSS OF POWER BRAKE ASSIST AND INCREASED BRAKING EFFORT WOULD BE REQUIRED. IF THE POWER STEERING FLUID SPRAY WERE TO SPRAY ONTO HOT ENGINE PARTS, AN ENGINE COMPARTMENT FIRE COULD OCCUR.

    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.

    Vibration Analysis Worksheet Service Bulletin

    1. 1Fault

    2. 2Finding the cause

      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).
