Yeah the spring are the same but the 2in block in the 4x4s. Z71 and the 4x4 dont really have anything different. I have had both they had the same skid plates, shocks and the gears and posi in mine. I seen nothing different but the stickers on mine.

 

this is what i did to my buddies jacked up truck it was doing it horibly but after that no more noise

 

damn never came back to chek on this thread i made... noise is driving me nuts!!

 

go to lowes or anywhere and get white lithium grease and fix it. easy solution!

 

but where exactly does it require to be sprayed on bro? sorry for the dumb question... not too mechanically smart..lol

 

well my problem got solved... the hardcore squeeking ended up being my rear passenger side shock

 

Well mine are doing the same thing now I know what to do !

 

my z had a bad squeeking from the back. turned out my bed bolts where loose. just a thought.

 

My last two truck both squeak but only when I'm off the pavement so it doesn't really bother me too much. That's something I should do more often though.
