Squeaking Spring bolt

[Muddinkev44]

Another noise my truck is making is when i did my new springs i used a 14mm 8.8 grade bolt and it squeaked everytime my suspension moved....so i replaced it with a 9/16" grade 8....and it is still doing it....it is driving me CRAZY!!!!!!!....i know they make greasable bolts that use sleeves but i had a hard enough time finding a 9/16" bolt 4" long....not to mention a greasable one.....any ideas...

My neighbor has the same issue. He fixed his with a can of WD-40. Just spray if all over the bolts and where you think the squeak is coming from. It fixed his...

ya i tried that a couple times and it didnt work....i used JB 80....its 10x better than WD 40 for lubricating things and it still squeaks
