on nbs trucks i hear a squeek that comes out of the rear suspension when the truck goes from a stop light, it also seems like the leafs or the axle shifts. what is it and how do you stop it?

 

try to tighten the u bolt on your axle.

 

There is a rubber bushing inbetween the leafs to keep them from squeking. After awhile they break down and they need to be replaced. Mine is doing the same thing. Check your u-bolts too.

 

you beat me to it

 

mine was doing the same thing so I went ahead and tightened them and problem gone

 

Slip Yoke.

 

i know the slip yoke problem, that is manly switching into reverse, this is something new, but ill try the bolts and rubber thing

 

I have an 04 4wd yukon sle with the Zw7 self leveling suspension and im getting a squeak from the left front wheel well when i drive and when i just bounce the car up and down when parked...is this the shock wearing out at only like 70,000?

 

Turns out it was the shocks, got a pair of OEM shocks on ebay for an amazing deal and out them on myself.....with parts and labor savings from going to a dealer probably saved like 500-800
