A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

G-179000	2017-08-15. Service bulletin. 13387 - Service Update. Dealers are to perform a drive audit. A small number of engines may develop a crankshaft bearing noise condition at low mileage. The drive audit must be completed before vehicle delivery (and in addition to normal pre-delivery inspection activities) to identify vehicles with the condition. If the condition is found, dealers are to replace the engine.
G-169470	2017-08-15. Service bulletin. 12313 - Special Coverage. The chrome layer on the balance chain pins may wear, allowing the chain to stretch. This would cause an engine noise, and if left untreated, could cause the chain to break, leading to engine damage. In addition, the fuel pump plunger shaft seal may wear and allow fuel to leak into the crankcase, setting P0172 DTC, and illuminating the Malfunction Indicator Light. This can cause engine run-on and/or the engine to run rough. If this condition occurs within the stated terms, dealers will replace the engine balance chain and fuel pump.

PIP5090C	2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have a noise, vibration or shudder on acceleration from a stop. Technician should replace the right hand axle shaft retaining ring. Technician will need to inspect the splines on the half shaft for damage. Technician should also inspect the splined end of the Power Transfer Unit for excessive wear.
PIP5090B	2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have a noise, vibration or shudder on acceleration from a stop. Technician should replace the right hand axle shaft retaining ring. Technician will need to inspect the splines on the half shaft for damage. Technician should also inspect the splined end of the Power Transfer Unit for excessive wear.
PIP5090	2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that have a noise, vibration or shudder on acceleration from a stop. Technician may find that the right front axle shaft is not fully seated into the Power Transfer Unit. Technician will need to replace the right hand axle shaft and retaining ring.
PIP3720D	2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician with the axel setup information from American Axle Manufacturing. 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.
