Axle Shaft Bearings

[andrewrj]

Ok probably a dumb question but I have searched several different sites and cant find the info I need. I just purchased 31 spline axles and thought they came with bearings but i was wrong. I want to buy new bearings but none of them have an application listed. They just have different sizes. Can I use stock sized bearings with the 31s or do I need to get a different bearing? If so, what size does it require? Any help would be appreciated because I have spent hours searching and came up with nothing. Thanks

Contact the axle manufacturer. The inner race MAY be different from axle to axle. I would think STOCK bearings would be fine but you should still contact the manufacturer.

All the 31 spline axle upgrades we've done (where I work) in the 8.8s (Ford racing or Moser axles), we've used or "re-used" (meaning they werent replaced) the stock/ stock sized axle bearings and seals for an 8.8.

Just go to the parts store and just specify your vehicle to get the replacement axle bearings....
