Hello Tony,

I really wish I had a database that tells me exactly what goes on each camper, but unfortunately, I don’t.

Based on my research, you should have a 4,400-pound axle (you can double-check your axle tag to confirm). If it is NOT a Lippert axle you will need:

Grease seal - RG06-050
Inner Bearing L68149
Outer Bearing LM67048
Race Lm67010
Race L68111

We have a kit that includes everything you’ll need: Dexter Bearing Kit for 4.4K Axles – Inner and Outer Bearings LM67048/L68149 # DX86ER. Just please make sure to check your axle tag.

If you do have a Lippert 4,400 pound axle, you will need:

Inner Bearing: L68149
Outer Bearing: L44649
Inner Race: L68111
Outer Race: L44610
Grease Seal: 10-19

Or you can get the Hub Bearing Kit for Lippert, Dexter, and AL-KO Axles - 3,500 lb with #84 Spindle # BK2-100. I know it says for 3,500 pound axles, but they are the same for the Lippert 4,400.

If you do not have some bearing grease on hand, make sure to grab some LubriMatic Prime Guard High Temperature Wheel Bearing Grease - Red - 16-oz Can # L11380.

Have you been on any awesome adventures this year? Where did you go, what did you see?

Hey Tony, did the Dexter bearing kit and grease work out for your Airstream Sport? Knowing how the fit turned out could help others replacing their bearings too.
