Rear differential failure?

Getting a weird click from the read end of the truck, entire drive line has been rebuilt less than a year ago and there is no play in the carrier bearing or any u joints

I can only hear it when the truck is rolling under 15 mph

any ideas?

 

Bump

 

A click can be a lot of things... Video with sound would help.

If I were worried about the diff I'd first drain the oil and see what comes out.

 

Change the diff oil and see what comes out. That would be the first step.

 

Is it worse when you are turning?
Does your truck have the mechanical lsd or locker?

 

E locked
I can’t tell if it’s worse or not when turning
Going to drain tomorrow

 

clicking on cars is usually CV joints
not sure about trucks

front LBJ's can also knock over bumps and stopping (both slow speed) but not result in eyeball detectable play with pliers

 

Well no pieces came out of the rear when I drained it

 

Just discovered my driveline came loose that’s what it was.. that could’ve ended badly..
