Control arm balljoint nut above subframe, what size?

[ChefSkinny]

Is it 21mm or 22mm? Also what do you guys find works best? Regular wrench? My sway bar will be out of the way.

Mine was a 22mm. And I used a regular wrench on one side and on the other I connected all of my extensions together and placed a swivel on the end and got it off that way.

Hope this helps. If not there a quite a few walk throughs for this through out the internet.

22mm.

I just used a regular box-end wrench on it. Make sure you use a floor jack right under the ball joint until it lifts up a little bit off the jack stand so that the ball joint doesn't spin. I actually used my foot to break it free, it worked rather well. I had a wall behind me so that helped that I had something to press my back against. You can even use your foot on the other side to pull it off.

^^ that doesn't seem very safe to me lol

I'm taking out the sway and everything so i'll try it with a wrench.

If you're like me...all the stores near by didn't have a 22mm so I used a 7/8ths instead...worked just as good.

I somehow managed to partially strip mine on the passenger side using a 22mm box wrench. PITA. I think I'm gonna have to try and hacksaw it off.

IIRC some are 21mm and some are 22mm. Depends on how old the car is.

My '87 was a 22mm

My 86 was a 22mm, the replacement control arms came with a 21mm locknut. So will be one of the two!
