2000 Z71 chirps tires when turning in 2wd
My 2000 Silverado Z71 with a 4" Fabtech lift chirps the tires when turning, both on the gas and coasting, and it also chirps the tires when I hit pot holes. I replaced the front axles today with the longer NNBS ones thinking that was the issue, but the problem is still there. It will also make a loud metallic bang occasionally when I hit a speed bump, sounds like it is coming from the front end. Inner and outer tie rods are brand new Moog.
What could cause this? The differential? Any suggestions of how to rule things out?

Alignment is not great. I need to replace the idler and pitman arm before I get it aligned though. Have the parts, but ran out of time today.

I would fix the steering stuff and get an alignment first! An out of alignment condition can cause the tires to squeal when you turn.
As far as the front end metallic banging noise check the fluid level and condition if you haven't already done so. There are several things inside that can go wrong in the front differential. Usually parts like bearings and gears have heavy wear.

Turns out it was a combination of a really worn pitman arm (the stud literally flopped around loose when I got the old one out) and being out of alignment. Changed the pitman and idler arms and idler pivot this weekend and it barely chirped at all, and just got it aligned today and now no hint of any binding or chirping tires.
