The Grand Design Imagine 2800BH uses 4,400 lb axles so in order to replace the brakes you can use the Electric Trailer Brake Kit part # AKEBRK-35-SA and in order to replace the hubs/drums you can use the Trailer Hub and Drum Assembly part # AKHD-545-35-EZ-K. If you're just looking for the bearings/seals you can use the Bearing Kit part # BK2-100.

I can help you with greasing up your EZ Lube Axle. First thing I would check would be that the grease is not coming out of the back of the axle through the seal. If this is the case you will need to replace the seal. Our tubes like #L11390 have 14…
