Dana-Spicer upper 4x4 control arms/ball joints
A friend of mine "in the business" had one of these and gave it to me wholesale, which is still not cheap, lol. More than a factory type replacement from RockAuto, but less than the Moog ones.
You can see the difference in the pictures below. This arm is wider, thicker, and does not have the "c-channel" type design of the factory arm, so it's not only thicker, on the edges -- it's much thicker in the middle.
You can also see how much bigger the ball joint is. I don't know if these ball joints can be changed out without changing the arm -- I suspect not (I'll find out though).
However, this ball joint is so much bigger it's not funny. Also, the tiny hole in the top of the new one is for a zerk fitting (which I hadn't installed yet) -- yes, these are greasable. They are filled right now with PAO based waterproof TomPac 2557 all-synthetic grease.
Maybe someone posted on these before, but I thought I'd add my impressions.
I just put this on the left upper on my truck. The  RIGHT upper got replaced 6 weeks or so ago for state inspection. My stock one was worn enough that you can FEEL the looseness with your fingers pulling/pushing on the ball -- but not as bad as my other one was.
I wasn't going to buy one this good since I'm throwing away the suspension when I put the SAS on, but it was a deal and will stand up well in the meantime -- or so I hope, lol.
