Re: installed new shocks and hearing new noise(s)... possible problems?
I've always tightened my endlink bolts with the car on the ground and haven't had a problem. There is no reason that you can't tighten these while the car is jacked up. Sway bars are loaded by translation of the endlink points, not rotation.
I think you are confusing control arm bushings with endlinks. This DOES matter for control arm bushings.
