Question:

I have a customer wanting to add brakes to a trailer axel. Here are the bearing and seal numbers BEARING LM48548 BEARING LM67048/Q SEAL 1716 I am wondering what hub /drum / brake and brake mounting flange I could use to do this.

Hey Eric, thanks for reaching out!

The closest thing I can find to what you're needing is the 4.4K Hub and Drum # 8-407-5UC3-EZ which uses bearings that match the ID of the bearings you listed, and it has a grease seal with a 1.719" ID. Does that sound about right?

If this is the case, then you'll need the Brake Kit # LC66WD if it's a Lippert axle, or the Brake Kit # K23-478-479 if it's from Dexter Axle.

If these parts don't look like they will work out then you'll need to custom order specific parts from Dexter Axle or Lippert.

Hey Eric, did the 4.4K hub and drum end up matching the bearings and seal you listed? Knowing which brake kit worked with your axle could really help others trying to add brakes to a similar setup.
