I've had the same thing on mine, which started a little less than a year after it was purchased. I've sprayed the crap out of both front springs, but to no avail. I'm still thinking it is either the springs or the swaybar bushings. Springs typically have a rubber coating near both ends & often a plastic insert. Once you have metal on metal grinding, that's when noises will appear.
I haven't crawled underneath to look, but are there just 2 rubber bushings, or are there more? All I found was this:

If anyone knows the exact dimensions of our swaybars & fittings, could you post the sizes here? Whenever I've had noise in the past, I've replaced with Energy's poly bushings. Does it look like they have something that would work:

JC Whitney also lists a pair of poly bushings for $15.99, so I'll probably order those and see if it helps.
