Snapping/popping noise

I got a popping noise that happens when my jeep sits for a little and when i go from take-off back or forwards there a popping kind of noise. But once it does the first time it doesn't do it anymore or barely 1-2 more times. Also when driving mainly in 1-3 gears and I let go of the gas pedal it makes a high squeak chirp/snapping noise. Or when on the freeway in gears 4-5.

I just had the rear drive shaft completely rebuilt by a very reputable place. So I don't think it is my CV making the noise but will check it out when I get a chance. The control arms were replaced not too long ago.

Any help would be great!

I have no usefull info for you but, the first thing that came to mind was a mouse eating rice crispies in your back seat. Snap,crackle,pop and the mouse squeaking

Sorry for my lack of help

It sounds like it could be the front drive shaft normally refereed to as angry sparrows. An easy way to check if it is your front drive shaft is to unbolt it from your front axle and tie it up to the frame. If the noise is gone you know the problem is the u joints.

I was just thinking u-joints but can't tell you which one...and even though just rebuilt....IMO that is no proof one of them can not be bad......

I think I've been hunting a similar issue but mine only happens on take off and only up to about 10-15 mph. Just a few "rattle-clacks". I'm down to thinking it's the front drive shaft ujoints so I'll be verifying that and replacing them next weekend probably.

Front driveshaft was rebuilt along with the rear, but it's not installed so the whole front is not in question. There is no play in the rear drive shaft at all. The noise is not constant and only happens for a second. It's starting to sound like something is binding though so it could be the CV going out. The shaft is still under warranty.

If you hear a horrible grinding thrashing sound followed by pieces of drivetrain spewing out all over the road, it was left in 4wd.

You didn't say if your Jeep if lifted or not. I've been noticing the same with mine. I have a pop when I back out of garage and occasionally at other times so I was thinking maybe I have some loose bolts in suspension. Got under there this afternoon and tried tightening several bolts. Only found one questionable on one of the frame to tub bolts. Everything else seemed tight. Maybe its just something to live with on a lifted Jeep.

Mine is lifted and SL has been for over 2 years...BL was done 6 months ago.

I have no "funny noises" I am a little anal like that, if there is a noise of something "loose" I tighten it up or replace it....one time was u-joint one time was upper rear shock mount broke other was still there...IMO if you hear noises something not right.

It is a lifted but I have never had this problem and until recently. And everything it snug and has not budged. Every bolt I tighten I mark them, so I can see if they move. I don't think its suspenion related because it happens on the freeway going 50-70mph when I have to let off the gas fast and it almost seems like the drivetrain is trying to catch up.
