First the background on the car. It's a 2017 series.yellow with flex Zs and spc rear lcas+toe arms. I'm pretty sure it was a stance car since when I got it it was lowered all the way down and riding the bump stops with uneven damper settings, ride heights, and preload at all 4 corners. Even after I raised it back to stock height it had about -3.5° camber in the back. I'm not sure what the front was but it was maxed out on the camber plates until I set it back to the 0 line on them. I destroyed the front right tire in about 3 weeks of owning it because the alignment was so bad. The front right also had 0 preload and was 1/2" lower than the left when I got it. After getting new tires and an alignment I double checked things a week later and all seemed well. A week after that the left rear slipped so far out that I was crab walking down the road and had to get my alignment redone. I also had a sway bar bushing in the front right that was obviously bad so I replaced my sway bar bushings with poly. (I tried getting OEM but they just never shipped and I had a deadline to autoX it.)

Ok now for the whole reason I'm posting this. The entire time I've had the car I've had an intermittent issue with weird wide left turns at between 50 and 65 where the car feels like it's loose then tightens up then gives again. Sometimes it will even trigger VSC. The easiest way to make it happen is a freeway interchange where you have to take a big sweeping left but it's not 100% that it will happen. I thought I fixed it with the alignment(s) and sway bar bushings but no. With the car in the air I don't notice any movement when I try to wiggle the wheels vertically like it would be a ball joint. I did get some play on the X axis when trying to check the tie rod but after I replaced the sway bar bushings I tried to check from underneath and I wasn't feeling any play anymore. I'm stumped at this point. I'm leaning towards either the pillow ball or the tie rod on the RF but I'm not sure how to be sure at this point. Any help or suggestions would be greatly appreciated.
