Clunk noise from rear end

I started noticing a tink/clunk type noise from my rear end when going over rough surfaces and potholes. Ive been driving with my windows open and I think its in the rear. Any idea what this noise could be or how I can figure it out on my own? I crawled around under my truck a couple times and couldn't notice anything.

 

More info would be helpful.
Stick or auto?

 

I have it too, not sure if bed noise or what!

early morning I get a "clunk" reversing out of my driveway. I attribute that to driveline bindage at the slip yoke. some day I will remove the boot and grease it.

when 4xing, I get it really loud in really twisty stuff. I know my frame and body twists in these situations, could be that, or again maybe the slip yoke releasing tension that it was holding due to a lack of lubrication. my dad's single cab does it too, and is all stock so im not too worried about it.

 

Well I have a stock Auto truck. Im getting a metal tink type noise from I believe the rear end when hitting potholes, uneven pavement, rough roads etc. I obviously don't get the noise on even surfaces. Really the noise is just annoying as I haven't noticed any difference in the handling of the truck. Ill have to see if it changes when the 4 wheel drive is engaged.

 

thanks. Im also not to worried but is there a formula to figure out these or other types of noises?

 

Check if your ubolts are tight first. Check everything for tightness actually.

 

Could be something as dumb as a loose spare in the carrier or gear in the bed pockets

 

I actually did check my bed I don't think its that but I will have to check the spare. Sorry for the noob questions but could it be my muffler/tail pipe moving?

 

bang on it and see if it makes noise.

 

Mine does it and so did my buddys 06 tundra

 

So clc, no formula but some good advise.
Check spare, all nuts inc. U-bolts for tightness, grease all drivetrain zerks, then on to mechanical issues, like u-joints. Do all this then get back with results. Good luck.
