First, let me introduce myself. My name is chance, i am 16 and own a 1999 dodge ram 1500, with 3 inches of suspension lift, 35 nitto mud grapplers, a chrome brush guard, cherrybombs and duals, a BOSS flip out touch screen, and 2 10 visonic subs with a 2000 watt amp. I have a problem, however. When driving, my truck makes an odd clicking sound, like hitting a tin can with another metal object. it seems to be coming from the rear, i would like to know if anyone knows what my problem could be, and what i can do to fix it. Much appreciated.

Check your u-joints.

Welcome to the site

You also need to check the oil level and condition in the rear differential

 

While you're under the truck manhandling the drive shaft to check for movement in the u-joints you should grab your exhaust pipe and give it a shake to see if it's tapping on anything. You should also smack the catalytic converter with a rubber hammer to see if it rattles.
