Ok before I get bashed I know I should search but I'm kinda lazy this am. So two of my buddies went through some mud and water about two weeks ago. No both of their rig's suspension squeaks over the smallest bump. I figured this was due to water and mud in the shocks or bushings. What causes the horrible noise?

 

Usually the sway bar mount bushings will start to make noise after getting sand and grit in them from going through muddy puddles.

 

Yeah! Going to have to rinse everything down and re-grease everything.
