I would be happy to help you find the correct replacement bearings and braking assemblies for your 2004 Keystone Montana 335RLBS Travel Trailer, but unfortunately the numbers you provided do not crossreference with any braking assemblies.

What you will need to do is remove one of the hubs and look for the bearing numbers stamped in the face of each bearing as shown in the included picture of the # L44649.

If you bearings are worn to the point that you cannot read the bearing numbers you will need digital calipers like # PTW80157 and will need to measure your spindle in the locations shown in the included diagram.

Lastly while the hub is off measure the distance between the brake mounting bolts center to center, and see if you have 5 bolts or 4 bolts holding them on.

For braking assemblies you will need to measure the distance between the holes in the brake mounting flange, and if your flange has 4 or 5 holes.

With the above information I will be able to recommend the correct components for you trailer.
