It’s time to put ball joints in the dodge so I’ve been gathering parts. Sounds like many folks recommend the AC DELCO pros. I ordered 3 off amazon and One off rock auto since amazon didn’t have all 4 I needed. Here’s what showed up first. Amazon has the dull knurled, rock auto was smooth polished one. So I returned the 3 amazon ball joints and ordered the rest from rock auto. And the ones that showed up today look just like the amazon ones. I don’t even know which one’s to put in since the body length and tapers are completely different from one set to the next with same part number. There’s been a mix of USA and Taiwan made parts 

I stopped into Napa and their house brand which looks like a rebranded ac delco is same as the knurled one’s. I didn’t want to step up to knurled but I’m under the gun so guess that’s what’s going in. Just a forewarning for anyone looking at ACD ball joints 

This kind of thing sucks, sorry to hear that. 

Think I woul call RA and ask them why.

Unless I missed it I couldn’t find a number for rock auto just endless web forms. I submitted a return for the smooth body one. Not sure if it was boxed incorrectly or what. I did send that picture to their Facebook page and got an email address to contact them. 

I got my original fitment spicer balls joints from local Sadler power train. Spicer has gone down hill from what I hear, I'm hoping I got old stock or maybe they get better supply as they rebuilt a ton of axles, gearboxes etc and they use spicer as main supplier. 

Idk anymore who to trust on parts, it's a gamble. 

Spicer was junk for me. I went to ACD and so far so good. I was all amped up when I got some made in USA parts from them only to be let back down when I got something else that was Taiwanese made. Like DF said, it's a gamble

Still on the the set I installed way back at 180k or so. I'm currently at 406k miles and still rolling.
