Tech Note 1: Pinion Seal
The Pinion Seal included with this Kit is a good quality aftermarket part. For a Premium Quality, Original Equipment Pinion Seal for your 2000-2007 truck, order optional QU11095 Seal.

Tech Note 2: Inspect
Inspect your pinion yoke hub for wear or damage in the area where the seal rides. Replace any yoke that has significant grooving or other conditions that could wreck or prematurely wear your new seal.

Tech Note 3: Pinion Bearing and Cup
Dodge used QU50570 Inner Pinion Cup and QU50571 Inner Pinion Bearing in 9-1/4" rear axles through 1999 and in some 2000 model year axles. Most 2000 and all 2001-2007 9-1/4" rear axles have the more expensive QU50606 Inner Pinion Bearing Cup and QU50607 Inner Pinion Bearing which have the same assembled external dimensions as the earlier numbers. This Kit includes QU50606 and QU50607 together to replace the 2000 model year QU50570 and QU50571 assembly but you should not substitute the earlier bearings on later axles due to load ratings.
