I've got a set of Buddyclub N+ Coilovers on my car and recently it's been squeaking recently when I go over some speed bumps. It also squeaks when I turn the wheel sometimes. I've degreased and gave it a quick wash (while on the car) as they are pretty old and there was a lot of buildup on it, the squeaking stopped for a bit and came back. Not too sure where it's coming from. Car feels completely fine when driven it's just the squeaking. Help me!!
