Stub axle carriers???
 

A little repair help and suggestions would be appreciated.

It appears that I need

3752 Stub axle carriers (2) (requires 5x11x4mm bearings).

What are the bearings? Do I need to replace them too?

I just got this car (used) finally broke it out before christmas. We couldn't hold out. :) Unfortunatly, After a jump off a dirt hill and it broke.

How often do these break?

Any tips on how to replace this thing? I'm assuming all I need is a hex key for the top ball joint, and it looks like just one nut to pull the rest apart?

THANKS.
