I'd give Quigley a call and get their recommendations specific to your application. They told me both specifications for torque and how to position the suspension prior to final tightening. I'm guessing you're talking about replacing the control arms and not torque arms? Anyway, the folks at Quigley are super easy to deal with (as long as they are still open for business)...
