Tech Note 1: Replaces
QU50746 replaces QU10869.

Tech Note 2: Installing
The initial overall length of this spacer 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!!! Never back off the nut to try and reduce the rotating preload of the pinion!!!!
