Hey guys,

I've been getting a clinking sound under my truck at super low speeds lately. It literally sounds like someone clinking two beer bottles together. It's rotational somehow, speeds up as I go faster. But it goes away at anything over about 4mph. Most predominantly heard in reverse, with the clutch completely out and no throttle added. I jacked the rear end up and spun the tires around, didn't hear anything, which is leading me to believe it's either driveshaft or transmission related. As any further investigation is going to require me setting the rear of the truck on jack stands with the truck running and clutch engaged in reverse while I get under it, I wanted to ask for any input here to see if someone else had experienced this and knows what it is. Hopefully to save myself a slightly dangerous situation lol. (I'll keep an experienced helper in the truck). Any help is appreciated!

Edit: added info

 

Mine does the same thing. Lol, haven't had time to investigate.

 

Check your U-Joints and the carrier bearing.

 

I agree with Edwin...those first. When was the last time you have had the rear brakes open? Maybe a spring or something has come loose?

 

just for piece of mind....check your lug nuts.

 

My wife says to stop driving slow.
