Have any of you developed a highly annoying creaking sound? I have front and rear sways and some days they creak like crazy, other days they're pretty quite. Its really driving me insane. I have Whiteline endlinks on the rear and stock links on the front, no beefy mounts or anything like that.

 

grease the swaybar bushings to the bar.

actually i recommend teflon tape..solved it pretty much permanently.
grease comes off over time..

 

How long have they been on? Did you grease them before you put them on? have you checked to see if the bushings are still in good shape and in place? They can shift.
Is the squeek front or back? Could be the front endlinks are giving out.

I'd get up under there and regrease the bushings and check to make sure everything looks good and is still tight.

 

I only have the rear sway bar, but so far so good. I haven't developed any sounds from it but I did slather on the grease when I installed it.
