Narrow it by model year, engine and more

Causes the technical documents say how to deal with (2)

  1. Hydro-boost brake assist and power steering share one hydraulic supply (four campaigns)

    3 matching records

    Some vehicles were built with an out-of-specification hydro-boost housing relief valve bore.

    The hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.

    What to do

    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. The PI document instructed technicians to diagnose the vehicle using the Power Steering Test Procedures if an owner complained about difficulty steering during "parking lot type maneuvers"; if the vehicle passed this test, no work was required, as GM viewed this as a normal phenomenon.
    4. Dealers replace the hydro-boost relief valve.
