Question:

Hi Will these drums work on these axles? I currently have 5x4.5 drums with electric brakes and easy grease Spindles on these axles? Thanks

Hey David, thanks for reaching out!

It sounds like you have drums for a 3,500 lb axle so in that case, yes, the Timbren Axle-Less Trailer Suspension # ASR3500S05 will work for your application.

To verify this on your end, your hub needs to use the following bearings and have these grease seal dimensions:

- Inner Bearing: L68149
- Outer Bearing: L44649
- Grease Seal: ID 1.719" and OD 2.565"

If you have something else please let me know and I'll be happy to help you find what you need!

Hey David, were you able to confirm if your hub bearings and grease seal matched the sizes listed for the Timbren axle-less suspension? Knowing what you found could help others checking compatibility for their 3,500 lb axles.
