I know it's probably my own fault...I could have cleaned my under carriage better after the April fools run. But I didn't so now I have a rediculous creak and squeaky rear end. I used some pb blaster thinking that might loosen things up and stop the noise, which it did for a day...
And I accidentially hit my shocks with the pb blaster an it seems like theyre creaking now too

Does anyone have an idea on how to stop the noise?? And help would be greatly appreciated! Thanks

It's not uncommon for dirt to get between the leafs and cause a squeak. Try pressure washing between the leafs and then spray some WD-40 in there. If that works, then add some sort of dry lubricant like graffite spray, which will last longer.

Check the top shock mount, If the nuts are too tight they may squeak. Should be at 33 foot lbs.

I had a squeak as well when I had dirt between the leaves.. so, try what Scott offered up as an idea and, once dry, drive the X around and see if it still makes noise.

To add to daggerdoggie's post, what I did with mine was jack it up and put some jack stands under the frame so the rear tires are up in the air. Then pressure wash the leaf springs from the side to get the dirt out from between the leaves. You can then put in some dry lubricant. You can get the graphite spray at truck stops or some auto stores. I had trouble finding it and ended up picking it up from a TA truck stop.
