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:Tyre failure (blowout, tread separation)NoiseVibration or shudderCorrosion or rustLights (headlights, turn signals)Warning lightABS activates (at low speed and the like)Reduced braking

Record by record

61 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.

Work done

How it is said to have ended

  • says it did not fix it1
  • 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. Recall2000 GMC YUKON ・ —

    Wheel Hub Assembly Bearing Nut Loosening Recall

    1. 1Fault

      • The inboard retention nut that maintains the hub bearing assembly can loosen, resulting in an ABS light indication, noise, and/or wheel separation from the vehicle; wheel separation can result in a vehicle crash.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. On 2x4 vehicles, raise the vehicle on an approved hoist first; the hub assembly is good if a yellow, green or blue paint mark is seen on the grease cap on the inboard side of the steering knuckle.
      2. If the paint mark is not present, remove the wheel and the brake rotor and clean rust from the hub assembly face to check for the date code stamping.
      3. Defective hub assemblies can be identified by the country of origin on the package together with a recalled date code, by the date code on the package, or by the date code on the hub assembly.
      4. If a round yellow sticker is present on the box label, the part is good.

    3. 3Correction

      Repair

      1. The hub assemblies were manufactured for aftermarket use; owners of these parts should have them removed and replaced as soon as possible.
      2. Federal-Mogul will replace the recalled hub assemblies free of charge.

    3. 3Correction

      Refinishing Aluminum Wheels This bulletin updates General Motor's position on refinishing aluminum wheels. GM does not endorse any repairs that involve welding, bending, straightening o re-machining. Only cosmetic refinishing of the wheel's coatings, using recommended procedures, is allowed. Evaluating Damage In evaluating damage, it is the GM Dealer's responsibility to inspect the wheel for corrosion, scrapes, gouges, etc. The Dealer must insure that such damage is not deeper than what can be sanded or polished off. The wheel must be inspected for cracks. If cracks are found, discard the wheel. Any wheels with bent rim flanges must not be repaired or refinished. Wheels that have been refinished by an outside company must be returned to the same vehicle. The Dealer must record the wheel ID stamp or the cast date on the wheel in order to assure this requirement. Refer to Refinisher's Responsibility — Outside Company later in this bulletin.

    Wheel Installation and Torque Techniques

    1. 1Fault

      • Vibration in the steering wheel or seat centered at 10-14 Hz, between 93-115 km/h (58-72 mph).

    2. 2Finding the cause

      Possible causes

      • Wrong wheel torque methods can mount the wheel and tire assembly off center, so its mass "orbits" the hub axis and vibrates like a tire with high RFV or an imbalance.

    3. 3Correction

      Repair

      1. Remove the tire and wheel assemblies, index them at least two stud positions from where they were, and reinstall them.
      2. With the wheel off the ground, install all lug nuts hand tight using only a socket.
      3. Snug all lug nuts in a star or criss-cross pattern with a hand wrench.
      4. Lower the vehicle until the tire has just enough contact to resist turning, then torque to specification with a torque wrench.

      Caution

      • This first order tire/wheel vibration may be misdiagnosed as wheel imbalance or excessive tire radial force variation.
      • Improper torque may also distort the brake rotor.
      • Do not use torque sticks or an impact driver to tighten wheel lug nuts.
