Review of Lippert Trailer Brakes - Electric Drum Brakes - LC66WD Video

The correct hub and drum assembly replacement for your Lippert 4,400 lb axle is the #8-407-5UC3-EZ. This comes with bearings and a grease seal. If you need brakes as well you can use the #LC66WD, or for self-adjusting brakes #K23-478-479.

From the axle tag you provided (thank you!), you do indeed have a 4,400 pound Dexter axle. The only hub/drum we carry that is compatible is the Trailer Hub and Drum Assembly - 4,400-lb E-Z Lube Axles - 10" Diameter - 6 on 5-1/2…

The recommended torque spec for etrailer electric trailer brakes #AKEBRK-35-SA is 45 to 70 foot pounds. For compatible nuts and lock washers use #BRKH10B.

According to Lippert that is a 6,000 lb hub and drum assembly with a 6 on 5-1/2 bolt pattern using #25580 inner and #15123 outer bearings. You do not need to use a replacement part from the same manufacturer so for a replacement you can use the…
