Question:
Should there be a washer between the outer bearing and axle nut? My e37YR axle/hub did not come with them. Thank you

Hey Dwayne, thanks for reaching out!
The Trailer Axle with Idler Hubs # e37YR will not need the washer because it is a 2K axle. If you had something like a 3.5K or up then it would need a washer, but the lightweight ones don't require them.
Are you installing the axle yourself?
