Yes the ball joints can be replaced, and I have a brand new set of the premium "forgeline" ones I could sell you if you want (long story, see my thread on the topic if you are interested)
You can replace the entire A-Arm with the ball joints and bushings if you prefer. If you use the standard OEM ones, with the OEM bushings, there should be no issue with the EPAS shudder. I'm pretty sure you can also use the GT500 a-arms, which have slightly firmer bushings, with no EPAS shudder problem but I am not positive. The shudder issue happens if you replace the soft OEM bushings with hard aftermarket poly ones; which means you cannot use the Steeda or BMR a-arms that come with hard poly bushings.
