Hey Goose, thanks for reaching out!

I sent your specs over to my contact at Dexter Axle who said your bearings are both L44649 which means you need the Bearing Kit # BK1-150 for both axles.

Is there anything else you're needing to replace/upgrade?

- Are you still feeling the need for speed?

Bearing show it’s for 3500lb axles. I think that’s wrong. Them axles are on a 35ft horse trailer that’s the GVWR is 18k.

@Goose Can you check the sticker in the middle of your axles and let me know what the weight rating for each axle is?

@JonG no sticker on the axles. They were made in 2003. Just the steel data plate with the numbers I gave that’s only on it. They are 8 bolt axles

@Goose Hmm, yeah 8 bolts for the wheels definitely won't be 3.5K axles. Dexter Axle is the only place I've ever been able to get info from, so if their info is wrong, the only thing left to do is pull a hub and either locate the bearing and seal numbers or measure the spindle where the bearings and the seal rides and let me know what you find. Odds are you'll need one of the following kits that uses 14125A/25580 bearings and the following ID seals: - Kit # BK3-210 seal ID is 2.125" - Kit # BK3-200 seal ID is 2.250"
