are 1994 Integra GSR and '90-91 CRX front hubs the same?

what about the bearings? they looked very similar when i had them apart.

 

Nope, hubs are different. Now if you had the 90-91 EX hubs and said the same thing, I may be inclined to believe you.

 

What's different? the spline count is the same. are the diameters for the knuckle different?

Hub, i mean, the part that has the wheel bearing surround it, has the wheel studs attached, and the rotor is screwed into.

the knuckle is the upright, which i know is different. the hub appears to be very similar in overall size and dimensions.

 

All you have to do is measure out the bearings and if they are the same that is the answer.
