slight churp from front end when taking off from a stop?!?!?!

[603 z71]

hey guys, my z71 is starting to bug me with this random churp from what seems to be the front end. balljoints are tight and greased both front hub bearing are new, tie rods are good, i doo have some play in the pitman arm but replacing that soon, rear u joints are new, i was just wondering if anyone has had the same problem at all?

Probably not the front end.

My truck makes a noise from the rear axel and after some research I have concluded its the leaves of the leaf springs moving across each other. Normally there are plastic bushings between them but they wear out. I put grease in there and it did stop for a short while but came back about a month later

Churps are usually u-joints. check the front ones. Could also be a drive pully. Those are a real pain to ID until they really start squealin tho.

Not necessarily the A/C, could be any of the pullys. Check the tensioner pully to see if yer belt is tight enough. A weak tensioner will lead to a churpy belt. You should see glazing on the belt if its slippin.

Cool. I would'nt worry bout it bein the front gearin tho. That would be more of a whine n grind.

In 2wd the front drive shaft should not spin, so doubtful the front dshaft u-joints are the source.

thats what i was just thinking, maybe a dry control arm bushing tht might be loosened from the sleeve but not show any play i guess?

I don't think your steering linkage is the source. There's nuthin up there that would chirp. My money is on a bad pully.
