Service bulletin PIP3720D
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.

NHTSA's summary
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.

| PIP5168F | 2018-02-21. Service bulletin. This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have a no crank concern. Technician will need to check the valve train for movement when the engine is cranked. If the valve train is not moving while the crankshaft is moving the front cover will need to be removed to inspect for a sheared cam sprocket locator pin. If the cam sprocket locator pin has sheared, replace the engine assembly. If the valve train is rotating during inspection, disconnect the Camshaft Position sensor and check if the engine will start. If the engine starts front cover will need to be removed to inspect for a sheared cam sprocket locator pin. If the cam sprocket locator pin has sheared, replace the engine assembly. If the engine does not start with the Camshaft Position sensor disconnected the follow published “Engine Cranks But Does Not Run” diagnosis in Service Information. Also perform an Engine Compression Test and Cylinder Leakage Test in Service Information documents all results. If the Service Information procedures above isolate an engine mechanical concern then removed to inspect for a sheared cam sprocket locator pin. If the cam sprocket locator pin has sheared, replace the engine assembly. |

| PIP4365D | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that have the transfer case is inoperative, difficult to shift or has no torque to the front prop shaft after 4wd is engaged. Technician will need to manually shift the transfer case. If the actuator shaft is bound up or all ranges cannot be obtained, then the transfer case should be removed for internal inspection. If the snap ring is found out of the groove, replacement of the actuator shaft and snap ring will be required. |
| PIP5102 | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that have Diagnostic Trouble Code P0016 stored. Technician will need to inspect the reluctor on the crankshaft. If the reluctor has moved replace the crankshaft. |
| PIP5087 | 2017-08-15. Service bulletin. This Preliminary Information communication provides information to the technician about vehicles that may have a service 4WD message displayed in the Driver Information Center. Technician may find Diagnostic Trouble Code C0379. Technician will need to inspect the front axle actuator connector for signs of moisture intrusion. If there is corrosion on the terminals at either location replace the actuator and harness. |
