I have been getting alot of grinding noise from the leaf springs anytime I hit a bump or the truck gets in any kind of angle in the rear. I have a 2.5 autospring level kit in the front and a 3" block in the back.

Anyway to eliminate the grinding noise of the leaf springs? I have tried lithium grease and that take some of it away but still can hear it.

 

I have a stock FX4 and my leafs squeak going over un-even surfaces or bumps. Kind of annoying even when I get out of the truck once my weight is off the truck you can hear it squeak.

 

I just had my leaf springs replaced on my FX4 and the noise went away completely. My truck sounded like and old person getting out of bed in the morning every time I went over a bump.

It's not a level if you have a rear block......

 

Yup basically in short that's what it sounds like. Been doing it since 3000km not even 5000km on it yet. Wonder if I can get that fixed like you.
