2017 Keystone Passport 153ML Replacement Bearing Kit

Question:

Hi I was wondering what the best way was to determine what axle seals and bearings I might need for my RV trailer? The Model is a 2017 Keystone Passport 153ML, can you determine the correct parts by that model or how would we do that? Thanks

Hey John, thanks for reaching out!

The best way to determine the replacement bearings and seals for your Keystone is to check what the weight rating is for your axles. Since your trailer has 2 axles and a GVWR of 4,500 lbs I'm guessing the axles are rated for 2,000 a piece.

If you can verify this is the case, then that means you'll need the Bearing Kit for 1" BT8 Spindle # BK1-100.

You can check the weight rating of your axles by either looking on the info tag near the front of the trailer, or by looking at the tag directly in the middle of your axles.

Let me know what you find either way!

Thanks for much for getting back to me, but I know for sure that I only have one axle not 2. Im sure this changes things. I couldnt find a tag or any marking on the axle itself. I was hoping I didnt have to take them out and get them matched up but that could be the case.

@John The photos I saw were showing 2 axles but maybe I just wasn't populating the right trailer. Yeah, without knowing the weight rating of your axle you'll need to pull a hub and see what your bearings and seal are.
