Question:
So I ordered the replacement hub kit but after getting the races they appear much different and wondering if I got the wrong ones or do yhe newer ones work on my GandG 87 boat trailer.

Hey there!
Thanks for sending those photos over! They help quite a bit, and I think I can clear up some of the confusion with the parts you ordered.
Looking at your measurements, I'm seeing approximately 0.99" on the spindle where the bearings ride and 1.25" where the grease seal sits. Those measurements are very close to what we're looking for with the Trailer Idler Hub Assembly # AKIHUB-440-2-G-1K, which uses 1" inner and outer bearings and a grease seal with a 1.249" inner diameter.
The difference is with the separate Bearing Kit # BK1-150 that you ordered. That kit uses bearings with a 1.063" inner diameter and a grease seal with a 1.5" inner diameter, so those components wouldn't be correct for a 1" spindle. The races are actually the same L44610 size in both kits, though, which is why those can still match even when the bearings don't.
The good news is that your new hub already comes with the correct-sized bearings, races, and grease seal for a standard 1" BT8 spindle. Your Bearing Buddy # BB1980A-SS is also compatible with that hub. If you want to replace the kit you have, you can do so with the Replacement Trailer Wheel Bearing Kit # BK1-100, which has the L44643 inner and outer bearings that you need.
I do want to point out that there's some pretty noticeable corrosion on your spindle. Before installing the new hub, I'd recommend checking the surfaces where the bearings and grease seal ride for any significant pitting or wear. If those surfaces are damaged, replacing the bearings alone won't solve the problem.
Could you confirm that you're getting approximately 1" at both the inner and outer bearing locations? I'd also love to know if you can find any numbers stamped into your original bearings. Those would help us confirm the fit before you put everything back together!
