Hey guys, just wanted to see if anyone had input or experience regarding this bearing/washer combo I came across whilst googling. I have a car with cheap coil sleeves installed on stock struts, and I'm doing a bit of troubleshooting. By the way, I am aware that that last sentence contains atrocious words(cheap coil sleeves, stock struts).. Words that only a young man with a microscopic budget would utter. Try to get past that before you bust the flamethrower out. SO, the car in question has a pretty bad case of "coil-bind" or "spring bind." That's not really a common term, so if you haven't heard of it, here's what I know: we're obviously talking about a macpherson strut setup here, so the strut and spring turn when the steering wheel turns. My springs get hung up somehow, if you get what I mean. There is tension in the steering wheel, particularly when stopped and turning the wheel. The tension builds and "pops," which is audible both inside and outside the car, and can be felt in the steering wheel. The "binding" doesn't just happen when stopped, so say you come to a stop and turn the car 90 degrees to the right. The springs don't want to rotate smoothly, and they make a little pop noise as you crank the wheel. The car now pulls to the right, as the spring doesn't want to rotate back to it's normal position after the turn is complete. They are square end springs, I feel as if the issue is pretty clear(in my head) and the base of the spring is just not rotating properly, particularly since it's under so much pressure. These roller thrust bearings I came across seem like they could be a solution. If not a complete fix, maybe they would "reduce the symptoms" a bit. Has anyone seen this in action on a car, or really anything in real life? I think the consensus will be that I should buy some and try it out, but I just wondered if any of you physics-inclined folks would have valuable input. I would appreciate it, and do flame on if you feel it is necessary.
