Front Lower Control Arm
The bushings are torn on both sides of the lower control arms. The driver side is completely torn and I can move it by hand jacked. I just picked up both control arms as I read its easier to install the whole unit vs. press out/in new bushings.
Any tricks to replacing them? What are the torque specs? Believe it or not I couldn't find this in my repair manual (anything regarding the control arm) .
I already purchased some Yuengling, Fat Tire and if that doesn't do the trick the grey goose is on stand by

You didn't mention what year or model you have but at least for the V8 versions you can use the heavier duty versions from the Turbo S. They have thicker rubber bushings which have shown to hold up much better than the regular ones. Not sure if they fit the V6 versions but probably do.
