F***! Help taking of chassis brace bolts

I'm doing my control arms, and I'm having the hardest time taking out the chassis bolts located by the LCAB carriers. its at an akward angle and i cant get much leverage, and even when i do apply alot of torque it slips. My car is on jackstands btw. can anyone recommend some techniques?

These shouldn't be particularly difficult to get out. And I just did this job a few weeks ago and don't recall these being difficult to "get at". If your car is on jack stands is it high enough that you can get underneath, because that's what you need to do. If not, you'll need to jack it up higher.

When you say "it slips" are you referring to the wrench? What, exactly are you using to try to remove them? These are either 16mm or 18mm bolts (can't remember which right now). If you've got the right size socket it shouldn't slip at all. If it does, you've got the wrong size. A 3/8" ratchet with the right size socket and maybe a short extension should do this job fairly easily. I don't know if you can do these with a simple open end or box wrench alone.

You can always try putting a piece of pipe on the end of the wrench, but it really shouldn't be necessary as the torque spec for these is only about 64ft.lbs. so they shouldn't be that tight.

Whatever you do, make sure you use the right size socket so you don't round off the head of the bolt, 'cause then you'll have a really hard time. If you don't have the right tools, either buy or borrow some before you go any further. Good luck.
