do 7k and 8k used the same axle spindle, just different bearings?

@BradS There are similarities and important differences between the bearings/spindle setups used for a 7 and 8K axle. Both use the same 25580 inner bearing, but the 8K uses a bearing that has a slightly larger OD. Also, the 7K spindles can use two different grease seals depending on the diameter of the spindle surface where the seal rides, one with a 2.125 ID, the other uses a seal with a 2.25 ID seal. The 8K uses a 2.25 ID seal. So, the short answer is maybe yes, maybe no. Hope that helps explain it for you!
