When Iaccelerate in drive or reverse from stop there is a creaking sound coming from the rear end. Only lasts like a second but makes the truck sound like an old POS. Thinking maybe the leaf springs? I put a coil spacer and lift spindles in the front and an add a leaf and a 3 inch block in the rear. Any ideas on how to solves this? Thanks in advance

 

Could need to bushing in your leaf spring eyelets as well as the pads in between the leaf springs itself are worn out. If you dont have any inbetween the springs then that could be your answer right there. Also check and see if the u bolts are tightened down. Maybe need to get up under there and just tighten it a bit more.

 

I just put everything in only a couple months ago and made sure the pads were in but I can't tell now because I just had the truck undercoated

 

well all i can say it double check it all.

 

You replaced the bushings too? And like mhockey said it could be the pads, not just from where you put in the aal but also in the oem springs unless you replaced those also.

 

Torque those U-bolts evenly and to the same #.
