Probably your spring bushings, as they wear they get noisy. check your bushings, bolts, equalizers, and hangers for wear and replace the worn parts and dont spare the grease when re-assembling. Dont forget to check the springs also for broken leafs or worn eyes. I put mine on 4 jack stands and dropped the axles to service them. Good time to check the brakes too. You will probably never stop all the squeaking but you can get it down to bearable levels.Last edited by 1stinLA on August 25th, 2014, 1:22 am, edited 1 time in total.
