3 The Axle Models-Carriers-Features chart on Page 2 lists all the variations of the carriers covered in this e : The carriers listed in this catalog do not include yokes. A yoke is a major assemblydifference, so a carrier sold with a yoke has a different assembly level number than the samecarrier without the charts for carriers, output shafts, and axle housings include the following information: An exploded view of each assembly, keyed to the parts list. A description of each part. Parts that are sold as assemblies that include other parts. Which carriers or axle models the part is used on. The quantity of the part used on the carrier or axle.
