I just installed raceland coilovers on my 2012 Scion tC rs7. Ever since i installed them I have been hearing a popping sound everytime I turn the wheel. That's one problem. Second, if you look at the top strut mount in the engine bay while I turn the wheel it will come out a little bit. Idk if it's suppossed to do that or not. People are saying it's supposed to and that it's not. Please help me with both.

 

Might not have the top hats tightened down all the way. Start there.
Then check to make sure your sway bar end links are securely tightened.

I've had mine on for at least 5K miles, installed them with in two weeks of bringing it home from the show room. Not one issue even with them maxed with removed collars.

 

top struts are def not suppose to move. that's SUPER unsafe. make sure everything is torqued down to spec.

that should also be the reason for the sound
