I just did this last night. Thanks for your DIY.
Another way to do it was just remove the inner fender liner instead of the belly pan. Doing it this way I was ably to do one side at a time with just a jack and jack stand. It's probably easier to remove the pan but I hate doing it haha.
Also if you look at the end of the arm on the knuckle side where the stud is, there is a spot to insert a torx socket to keep it from spinning.
The T-40 attached to a ratchet, with a 21mm wrench already on the nut, this worked great to hold it still and tighten it up before final torque-ing .
It's a T-40
And be careful not to install the control arm upside down like I did the first time
