    torquing rear upper inner control arm bushing under load

    I installed new rear upper inner control arm bushings and am wondering how to tighten this under load. I was planning on putting the front of the car on stands and leveling it with the rear wheels that would be resting on ramps to put load on the rear, but it doesn't seem like there is space to put anything on the nut going through the bushing that is on the front side of the subframe. Any advice on this?

    Isn't that a self locking nut? One with the tab that holds the nut in position?

    Or are you talking about something else?

    Right you are. I know I was able to get a wrentch on it. At the time the muffler was out. I also recall it was a bit of a pain. But without getting the car up off the ground and taking a look, my recall is a bit sketchy.

    I did something similar to what you suggested. Front end on jackstands and rear end on ramps at roughly the same height as the front. It's not perfect because the suspension won't be fully settled, but it should be good enough. If I recall I used a pair of wrenches or a wrench and a torque wrench and was able to get them in there without issue.
