We have now tried loosen the bolts to some bushings and etc when the car is on a lift with the wheels in normal mode, maybe it could be that there is a pressure in the bushings when everything is working in another angle. But that wasn't the problem either. The shop came to a conclusion that its probably the springs squeaking up against the rubber seat on top.

I have been in contact with H&R, and they are telling me I have to buy a tube that we put on the springs. But not enough that I have to pay extra for the tubes, we have to take appart everything again at a shop, and do another wheel alignment. I'm kinda pissed over this. They should warn you when you buy that this could occur. Then I would have bought it straight away. Its not the money for the tubes, but the whole job off doing everything over again.

Thank you!
