Upper Control Arm Mounting Thread Size
Does anyone know the thread size on the studs that hold the upper control arm to the frame? I needed an impact wrench to get the nuts off because the threads were so rusty. I want to clean up the threads on the studs and nuts so that I can get a good clean reading on the torque wrench when I re-install everything.

Re: Upper Control Arm Mounting Thread Size
I would not clean them off too much. I brushed mine and reinstalled them. Tight them snuggly. When you get a front end alignment, they'll torque them for you.
