Popping noises from front of S14 afer installing coilovers

So I just installed some Megan street coilovers, and something in the front is making all sorts of noise. First I noticed a bad popping noise when I turned the wheel. It sounds something metal is hitting on something else. Or maybe spring noise. It does it when I turn the wheel from dead center in either direction, and it only does it in one spot, then when you hit that spot again on the way back in makes it again. Thought maybe I over- or under-tightened something, but I checked and it's fine. Then I noticed another noise...this one sounds like something is loose and is rattling, and only happens when I go over bumps. It's really bad with the windows down, but inaudible with the windows up. Again, everything is tight. And the last, which is also the worst by far...whenever I turn the wheel to the right, at around 40MPH or higher, it makes a really loud repetitive popping noise, almost like a machine gun. It's so bad that I thought I had a flat tire at first. My dad suggested maybe the wheel bearing is going out. I sure hope not. See, this what I was afraid was going to happen. Any suggestions?

Edit: Also, I installed like new TC rods a few months ago. Also also, none of these noises happened until after I put the coilovers on. But it's such an easy install, I don't think I did anything wrong.

Did you set the spring load???? your perches might be loose, take off your wheels and double check them.

It could be a ball joint I suppose. Although that first popping noise has mostly gone away. I didn't put any preload on the springs, because I remember reading somewhere (either on here or on nico) that someone asked megan about that, and they said they recommend no spring preload, just make sure that there's no gap between the perch and the spring. So that's what I did. I also know that the coilovers are on the correct sides; there's only one proper way for the brake lines to fit in. The perches are not loose; I checked. Nothing is loose...anymore. That rapid popping noise when turning to the right was because the front right wheel wasn't on tight. Not sure how that happened, as I know I tightened it down. I guess it wasn't tight enough. That went away. In fact all noise is for the most part gone. The only one that is left is the one coming from the front left wheel, where it sounds like metal rattling. I will check the spring on that wheel again to make sure there's no slippage.

Some coilovers are touchy about how they sit in place. The strut / shock whatever it is (I cant think right now) maybe out of alignment / place when you lowered the car back down. Lift it back up and then check the position of the strut / shock. Usually the popping noise comes from a shock / strut out of place.
