   What the documents say to do

   Brake pipe (brake line) corrosion and rupture

   Confirm

   • In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).

   Repair

   1. GM recommends replacing the entire set of pipes whenever any pipe leaks or is corroded enough to need replacement.
   2. On June 28, 2013 GM released 66 new part numbers for servicing brake pipes in 1999-2007 GMT800 pickups and utility vehicles.

   Caution

   • Analysis of repair records indicates that consumers often elect to repair only the failed circuit.

Wheel Hub Assembly Bearing Nut Loosening Recall

1. 1Fault

   • Noise
   • Warning light
   • ABS light
   • 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

   • Inboard Retention Nut: loose or misadjusted

   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

   • Hub Assembly: replaced

   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.

   Parts

   • The recalled part numbers are 515020, 515021, 515025, 515053, 515054, 515059 and 515060.

Front End Alignment - Missing Dowel Pin Recommendation

1. 1Fault

   • While performing a front end alignment, the upper control arm bracket alignment pin may be found missing.
   ↓→

2. 2Finding the cause

   Possible causes

   • The pin serves as a pilot for the alignment cam when adjusting the front caster and camber.
   ↓→

3. 3Correction

   Repair

   • If the pin is missing, a 1/4 inch dowel rod or a punch can be used as a temporary alignment aid to center the cam to the bracket while making adjustments and torqueing the control arm nuts.

Vehicle Lean Preliminary Information

1. 1Fault

   • Lights (headlights, turn signals)
   • The procedure is for customer complaints of the vehicle leaning left or right, whether the lean appears in the front, the rear, or both ends.
   ↓→

2. 2Finding the cause

   Steps to confirm (in the document’s order)

   1. Measure the fender wheel-opening heights, front and rear, to quantify the lean.
   2. P height and R height are each the distance from the ground to the highest point of the wheel opening, measured through the center of the wheel.
   3. If the left-to-right difference in P and/or R height is 1/2 inch (12 mm) or less, no repairs are suggested because the vehicle is within specification; if it exceeds 1/2 inch (12 mm), follow one of the three diagnostics.
   ↓→

3. 3Correction

   Repair

   1. Generally the stance can be adjusted with the torsion bar adjuster bolts.
   2. If Z height is out of spec and the D height difference is greater than 1/2 (12 mm), adjust Z height until it is within spec and the P and R height differences are less than 1/2 inch (12 mm).
   3. If adjustment is not possible, check the front eye of the rear leaf springs for matching color-coded tape or paint; if the two sides differ, switch the springs side to side, and if they match, replace the leaf spring on the lower side only.
   4. After all adjustments are done, perform a front-end alignment and check headlight aim.

   Caution

   • Before measuring, set the tire pressures to the pressure shown on the certification label.
   • Before measuring, check the fuel level and add weight if necessary to simulate a full tank.
   • The P and R heights are not set at the factory, and no specification is given for them.

Tire and Wheel Size Change Information

1. 1Fault

   • The document covers changing the tire size on mid-size and full-size trucks and utilities.
   ↓→

2. 2Finding the cause

   Steps to confirm (in the document’s order)

   1. A calibration exists for 20" or 22" wheels and tires on full-size trucks under the latest version of TSB 03-03-10-006 or 06-03-10-011.
   2. A calibration is available only if a vehicle of the same model year, body style, engine size, transmission type, axle type and suspension type can be built in the sales order guide with that tire.
   ↓→

3. 3Correction

   Repair

   • Once the tire application is confirmed in the sales guide, contact the Techline Customer Support Center (TCSC) to determine calibration availability.

   Caution

   • GM supports a tire calibration only for tires that have been sized, tested and designed for the vehicle and its applications.
   • Do not use the tire size selection offered in the ABS module as a guide to which tires fit the vehicle.
   • Changing the tire size in the ABS module affects only the wheel speed sensor calibration inside the ABS module; it does not correct the speedometer, and does not change the rear speed value on vehicles that take rear wheel speed from the ECM/PCM/VCM via the VSS.
   • The customer may be charged for this service; it is not covered under the manufacturer's warranty.

   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 or shudder
   • 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.

Preliminary Information - Vibration Diagnosis Using Pico Oscilloscope

1. 1Fault

   • Vibration or shudder
   • Customer vibration complaints are among the most challenging to diagnose and repair accurately.
   ↓→

2. 2Finding the cause

   Steps to confirm (in the document’s order)

   1. Drive the vehicle to verify the condition and record a Pico data file of the concern.
   2. Review the Pico file and use it to help determine the root cause or component.
   ↓→

3. 3Correction
