Which seal?

[jcyamaharider]

I have done a search on here in regards to which seal to use while replacing wheel bearings and there seems to be a discrepancy. I have seen a seal with an inner diameter of 1.68 being used and also 1.719 being used. The 1.719 comes in most kits so which one is the correct one? Or do I just have to pull my trailer apart and find out for myself?

Thanks

Here is what I used. Northern Tool is where I got it from . My trailer was it 2011 MFI

The numbers are a little bit easier to read on the bearing kit

So I measured my spindle and the part where the seal actually seals is the 1.685 so I may be buying different seals if these do not interfere enough.
