hey guys and gals. I have been replacing parts and i am sick of throwing money at this thing. I was wondering if anyone had any idea what a sound like a spring and pop when turning the steering wheel. Cadillac dealership was no help. they blamed it on my BC coilovers, but I replaced the pillow ball mounts and spring purchase isolaters on those too and nothing... im at a loss. I own a 2013 ATS LUX AWD. on the suspension I have bc racing coilovers and moog all metal sway bar links are the only thing i have modified. I have also replaced all the steering joints from the gear box to the steering wheel.
