Lower Control Arm Query

[Stock]

Hey all,

 

Got a quick question about the lower control arm on the facelift Z. Need a replacement arm as the bushing is going bad on this one. Had a look around and can see the most common option available are arms for pre-facelift. From my brief research, the ball joint thread is a different thickness between the two? Assuming I have two options, I can find a facelift arm and should just bolt in with no issues, other option is to buy a pre-facelift arm with ball joint and replace both?

 

Would appreciate any advice, cheers!

I'm assuming the arm (red) needs to match the thread of the ball joint (green).

Seemingly enough there is a topic in the modification threads for lower arm/ balljoints, similarly someone else has also come into the fact of the difference with two ball joints- Zmanalex has said that you can match arm and balljoint and it’s the width of base of the balljoint which fits up inside the arm that changes the length/ fitment of the thread so depends how much money you want to spend I guess, but I’d definitely trust Alex’s knowledge- hope this helps

Been a while since I last posted, but having another look - there is a difference between the arms as well - the recessed portion where the ball joint sits is deeper on the pre-facelift as on Conceptz links below - this means you will need to buy a matching arm as well for full compatibility:

I'm assuming most of the discount eBay arms are for pre-facelift.

Checking Nissan EPC also shows pre-facelift is 54501-AM601, facelift is 54501-AM602.
