I have a 06 s60R that ive noticed sits lower in LF corner then the RF corner. I have measured from the floor to the fender on both sides and Lf is an .5" lower then the right side. I don't notice any noises like a broken or bad spring. I did change the spring seats a couple months ago and notice the shaft of the shock did not pressurize itself back fully, I had to pull the shaft back out by hand to reassemble everything.
