An issue has recently come to light that I felt warranted documenting and spreading the word about. It seems that in addition to the original design of the rear upper control arm to subframe bushings there is also a flawed design that's been infiltrating the market over the past few years...
Read thru that.
If you search, you might find a thread that will tell you the easy way to do them.
Then, order some poly (for street usage) or delrin (which is what all the Big Boys use!) spindle bushings; I'd go Prothane black instead of my ES blacks since Prothane impregnates the poly with graphite, but you do you. (I have Energy Suspension because I didn't know that. They don't squeak, but eh.)
For the inner LCA bushings, poly or delrin. Delrin again is what the big boys run; poly can take a set it seems.
Because I have a detailed list of my ongoing build, I'll share. I'm posting from my phone right now, so the list is zoomed in a bit. I'd advise you replace the toe compensators as well, but that could be done later as it's an easy access item unlike removing the knuckle for everything else.
Anyway, you are looking for the parts listed in red. My parts here are a mix of OE spec, prothane, and polyurethane. The arm itself isn't available for sale unless you go with the SCP unit that costs just a notch below your first born.
