Applications
Tech Note 1: Kit Includes
QK8008 Kit includes these genuine AAM Original Equipment Parts:
QU10868 Pinion Seal
QU11124 Pinion Wear Sleeve
QU10877 Pinion Nut
QU10876 Pinion Washer
QU10867 Pinion Preload Spacer (Crush Sleeve)
Tech Note 2: Always Replace
Always replace the pinion seal and wear sleeve at the same time. If you experiencing a pinion seal leak, chances are both the seal and wear sleeve are worn or damaged. The AAM 1150 Rear Axle uses a factory two piece pinion sealing system that includes a replaceable wear sleeve on the pinion flange that generally eliminates the need to ever replace your pinion flange to solve an oil leak. On the AAM 1150, you replace the inexpensive yoke wear sleeve along with your pinion seal.
Tech Note 3: Included Pinion Seal
The new pinion seal included in QK8008 Kit has a factory lubricated seal lip to provide initial lubrication of the seal. If the lube gets contaminated or is missing, clean the lip apply clean grease before installing the pinion flange on the axle!
Tech Note 4: Common Seal Failures
Many pinion seal leaks are caused by pressure building in the axle due to a clogged axle vent system. Always check and clear the vent system. Other common causes of seal failure are installation errors, incorrect pinion bearing preload (too tight or too loose), not lubricating the seal lip and yoke with clean grease, and object damage such as getting grass wrapped around the Pinion Yoke.
Tech Note 5: Replace Old Crush Sleeve
Your AAM rear axle uses a collapsible spacer or crush sleeve to set pinion rotating torque. To accurately set pinion rotating preload, you should replace your old crush sleeve with the one provided in QK8008 Kit when you replace the pinion seal.
Tech Note 6: Tightening the Nut
With a new crush sleeve (pinion preload spacer), the initial overall length of the sleeve is greater than the normal separation distance between the outer pinion bearing and pinion shoulder. As you tighten your pinion nut against the yoke, you will push the outer bearing against this Spacer. At that point the nut will seem tight but your pinion will still be loose. You now must increase the torque applied to the nut by a substantial margin to initiate the compression of the spacer. Once it starts to compress, the required torque needed to continue tightening the nut will still be high, but reduced from the amount needed to start compression. As the spacer collapses, your pinion end play will gradually disappear. When all end-play is gone, you have to be very careful as it will only take a small movement of the nut to go from too loose to too tight. If you over tighten the nut, you MUST get a new spacer and start over!!!
Tech Note 7: Torque
Pinion Rotating Torque should be measured with a beam or gauge type inch pound torque wrench. To get an accurate torque reading, you should remove the axle shafts as the drag from your wheel bearings and brakes will adversely affect your results. The rotating torque values listed in my Dodge Ram Shop Manuals are:
Pinion Only Torque to Rotate with NEW Bearings (Diff out of axle): 15-25 lb in (1.69-2.82 Nm)
Pinion Only Torque to Rotate with USED Bearings (Diff out of axle): 10-20 lb in (1-2 Nm)
Total Torque to Rotate with NEW Bearings (Diff in axle): 30-50 lb in (3.4-5.6 Nm)
Total Torque to Rotate with USED Bearings (Diff in axle): 25-45 lb in (2.8-5.1 Nm)
Rotate the pinion several times to seat the bearings before taking a final reading

QK8008 11.5 Pinion Seal Kit
I was parked on a serious down slope for two days and the rear pinion started leaking. So I ordered up a new set and as advertised they fit my 2006 Doge Ram 2500 with AAM 11.5 rear axle. The job is not difficult just need a 36mm, 12 point socket to remove union nut.
