axle noise?? did search no luck

[little79k5]

jumped in the k5 today and soon as i started driving, i noticed a little clicking from rear of the truck. it stops after i get up to about 20 mph. and its weird cause it just started after i havent driven it for a day. some sort of axle problem?? its a 10bolt

Check your brake internals, your u joints, and any other rotating component.

i dont thinks its ujoints cause i just put in a new cv shaft last week. i can only hear it from like 0-15mph.
i read somewhere it could be a wheel bearing?
