Feel free to make fun of me... I spent about 8 hours (yesterday and today) getting the old rear upper control arm out... :favorites68:
I don't think the parts back there have ever been replaced in 140k miles, and the previous owner apparently never washed the undercarriage because everything was covered in rust.
It quickly became clear that the pinch bolt holding the ball joint in place wasn't coming out, so I decided to take out the entire bracket. I had to take off the weird vibration dampener to get access to those bolts. That went pretty well, the bolts for the dampener came out without any real issues. But those three 21mm bolts for the ball joint bracket... ugh. Big bolts, coated in loctite from the factory, and rusted over on top of that. Plus, because there's not much space to work back there, I couldn't get my long breaker bars in there.
After I eventually got the control arm (with attached bracket) out, it still took me more than an hour to get the ball joint to pop out of the bracket.
Hopefully I'll be able to get the new arm in tomorrow before I have to go to work in the evening.
Going to do one more thing tonight... take a wire wheel brush to those three 21mm bracket bolts, and get all the remaining :favorites68: loctite off...
Yeahhh I left that bracket attached to the control arm when I threw it in the trash :happy175:
I seriously considered it, but a new one is like 350 bucks... Plus I need my car to go to work (50 miles away) the next 4 nights, so I can't wait for parts to get here.

Well, the new rear UCA is in... mostly. No matter what I try, the pinch bolt just won't go through. But the ball joint stud seems to be in there pretty well, even wacking it with a big hammer didn't make it come loose. And since I don't do any offroading or anything I figure it'll be fine.
I ended up leaving the sway bar out (had to remove it to be able to get the ball joint bracket off). I had planned on putting it back in, but I just couldn't get it to align properly. After about 20 minutes of fighting with it I decided to hell with it. Drove about 50 miles on the interstate with 60+ mph wind gusts, and didn't notice any difference.

sway bar back there is useless anyway...and for the pinch bolt you can install it backwards with a piece of bar or even small piece of wood at the end of the bolt ( blocking it from going through the other side) to open it up.....cant think of how to describe it best....theres a picture floating around somewhere for the front clevis but same idea...might be in the westway lift thread. anyhow id recommend having that bolt in there

its about 3/4 of the way down or so, i think hes using a padlock
There are no threads on the inside of that pinch bracket, so the trick he used for the clevis won't work. Anyway, that's not the issue. The bolt is supposed to slide through the two holes in the bracket and the notch on the ball joint stud, then you just tighten the nut on the end of the bolt that sticks out. But for some reason the bolt won't go further in than maybe half an inch or so.
Next time I have a day off work I'll see if I can figure out what exactly is going on with it, but this will have to suffice until next week. I'll just keep a careful eye on it until then.
