2023 Jayco North Point 5th Wheel Travel Trailer - Replacement Brake Pads For Dexter Tow Assist ABS  

Question:

Expert Reply:

Terry, the quickest way is to check your axle tube diameter and then confirm with the axle tag if you have it:

~3 inch tube 7K axle with tow assist abs = use # DX69WR Left and # DX79WR Right

~3-1/2 inch tube 8k axle with tow assist abs = use # DX55WR (includes left and right as a pair)

Bearings can help confirm, but they overlap a bit: both 7K and 8K use 25580 inner bearings 7K may use 14125A, 15123, or 02475 outer bearings, while 8K uses 02475 outer only. Because both families use 12-1/4 inch diameter brakes but different shoe widths and hardware, it’s important to match by axle rating tube size/tag before ordering.

Let me know if you have any trouble still figuring out the axle capacity/size, and I can provide some more insight.

Thanks Andrew. I crawled under the trailer and found the tag - definitely 7,000-lb Dexter axles. The tubes measure right at 3", so I ordered the #DX69WR and #DX79WR. Should I replace both axles at the same time, or can I do one for now?

@Terry Good work, Terry - that 3" tube and 7K tag confirm you’ve got the right set. It’s best to replace both axles’ brakes together so the Tow Assist system sees equal braking performance across all four wheels. The ABS reads wheel speed from each hub, so keeping both axles matched helps the system balance braking smoothly. Once you’ve got them installed, watch for the solid green indicator light - that means the sensors are talking to the module correctly. Let me know how the install goes, and other Jayco owners feel free to chime in if you’ve noticed any differences after replacing both axles.
