FRONT WHEEL BEARING REPLACEMENT
When replacing the front wheel bearings it will be
necessary to identify which bearings fit your
wheel. Measure the bearings. If the bearings
measure .950 inches then it is necessary to use
bearing kit number AUBl63491. If the bearing
measures 1.950 inches, then it is necessary to
use bearing kit number AUBl63555.
You can also identify the bearing kit by the end
caps. If the end cap is stamped, then use kit
number AUB163491. If the end cap is powdered
metal use AUBI 63555.
