Squeaky leaf spring bushing

So the front rubber bushing where my leaf spring attached to the truck pretty much sounds like a banshee from hell! It's only the passenger side where it attaches in front of the back tire.I pressure wash the underside of my truck on a regular basis. I've tried wd40, and other lubes but nothing will shut the stubborn thing up! Do I need to take the bolt out and grease it all up? Any suggestions?

 

ive got the same issue...saw that a few places online had the bushing set for $15...that may be worth a shot

 

WD40 will just make it worse in the long run. Not a true lube, more of a penetrating fluid. Best bet is a new bushing - they aren't expensive.
