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.

Your dealer will reprogram your OnStar module with an update. This is for vehicles that have previously received the Canada upgrade as described in Service Bulletin #15-08-44-001F."

Tech 2 The Tech 2 is used to set up a replacement BCM, which includes loading the odometer value that is displayed and stored in the IPC. A replacement IPC will display the previously stored vehicle odometer value, communicated from the BCM, after cycling the ignition or driving the vehicle. *The odometer programming is integrated as part of the BCM programming procedure. It is not a stand-alone event.

The customer communication requested return of unsold inventory to inspect for a software issue. If the software issue exists it can cause a fan in the climate control system to stay on even when the ignition is turned off. The fan staying on even though the ignition is off can drain the battery, making the vehicle unable to start.

The customer communication requested return of unsold inventory to inspect the software. The software may have a fault where the readiness monitors are stuck in the not-ready or incomplete position. The readiness monitors will not cause performance or emissions issues but will prevent the emissions scanning tools from confirming the module is performing correctly, causing the vehicle to fail state required emissions tests.

documentation and claim submissions

Technician should be advised that the maximum pinion shim to be used or stacked behind the pinion is 0.050?, and the minimum pinion shim is 0.020? for an 8.6 axle. The range for available pinion depth shims for the 10.5? axle is 0.006? to 0.024?. When setting the backlash it should be set between 0.003? to 0.005? on a new ring and pinion for any American Axle Manufacturing application. The ring and pinion can be reused or adjusted if the mileage is less than 500 miles, if not used for towing. Technician should be advised that a ?roller coaster? or ?hourglass? pattern on the bearings may be normal up to 10,000 miles and possibly longer. With a mis-machined housing you may get a heel pattern on both sides of the gear teeth at build up can generally be corrected with backlash adjustments. When setting up an 8.6? axle with a 5 cut gear set is to use a 0.035? pinion shim and set backlash to 0.004?. When using the newer 2 cut gear set also use a 0.035? pinion shim and still set backlash to 0.004?. To set the gear pattern use backlash to adjust the pattern heel to toe. Use the pinion shim to adjust the height of the pattern. The proper drive pinion bearing pre-load is from 15 - 30 inch pounds with new bearings. The total torque to turn after the differential case is installed should increase 5 - 10 inch pounds at the pinion. A new pinion nut must be used whenever the old one is removed. The axle shaft end play specification is 0.012? per side and the radial specification is 0.002? - 0.003?. Technician should be advised that synthetic lube can be used in all new American Axle Manufacturing axle assemblies. The new pinion seal for the 8.6? axle assembly is a two piece design.
