Some people prefer knuckle rebuild kits with brand name Japanese "Koyo" trunnion bearings. Other than the brand of the bearings, the only difference in this kit is that the outer felt rings are not included since, in most cases, people opt to install upgraded knuckle ball wiper seals and thicker rock rings anyway. Both kits provide excellent quality and durability for our customers - it's really just a matter of personal preference.
NOTE: We recommend checking your wheel bearings and spindle bushings for wear as well. When you're in the process of rebuilding the axle, it's a good idea to protect your investment and just replace these relatively inexpensive items. In the event Koyo trunnion bearings are unavailable, these kits may ship with Schaeffler/FAG bearings.
