Hey guys so I'm refreshing the front end on my nb1 (knuckles, bushings, inner/outer tie rods etc). I bought new left and right knuckles from Mazda and new hub/bearing assembly from Mevotech off of Rockauto. Yesterday I go to press them together and they just slid right together with only hand pressure. I was pretty sure these are supposed to be interference fit but maybe I'm wrong. I checked both part numbers and they are correct. Any ideas?

 

Your talking about the hubs on the stub axle? They should slide on.

 

Fronts no press.
Rears 20 ton press.

 

Yeah where the bearing assembly slides onto the spindle of the knuckle. Im like wtf is the inner race undersized because the knuckles are brand new oem?? lol Ok cool thanks for the help. One more thing though, no lube on the spindle correct? you want the contact of the spindle and inner race to cause the turning effect not the inner race spinning on the spindle itself, no?

 

I put a little grease on the spindle just to ensure it's easy to get the hub off next time I replace it.

 

Those are so clean!

My spares are rusted to hell from sitting outside. Haven't had the motivation to clean them -_-
