Default clicking from rear end

ok well was driving my FRC home yesterday and i can hear a clicking coming from the rear of the car upon acceleration and deceleration but it ceases as soon as the car comes to a stop it does get louder when taking curves at more then 20 mpg when at higher speeds noise is not noticable or cant be heard. im assuming wheel bearing, going to put it on the the lift tommorow just bored at work figured id throw the issue up and see what to expect tommorow. thanks

Could be a worn or broken spline on an axle shaft.

Not an absolute but probably the easiest fix you'll find. If you hear this clicking when slowly moving out then its probably the splines of the half-shafts have dried out. You'll need to remove the axle nut, get some spray lubricant and lightly spray the splines. Don't over-do it as you might get lube on the brake rotor which would be bad. Put the axle nut back on and torque. I don't remember the torque value this second but its up there. Repeat on the opposite side.

Someone needs to explain to me once and for all why these splines need to be greased, apart from ease of disassembly. There is no relative motion taking place between the CV joint and the hub, either rotational or in-out. The two are clinched tight with a big a$$ nut. Why grease it??

Had the same problem with my 03 z06. I just tightened the axle bolts and it fixed the problem. I think I set it at 160 lbs.

Check the Ebrake and sensor wires. Mine were hanging a little loose and hitting the weights on the wheel used for balancing. Zip tie fixed it.

I have no idea why, but I had clicking ONLY when shifting my auto from park to drive/reverse. After reading about this on the forum, I did the grease the splines thing and the noise is gone for over a year now!

The half-shaft is designed to "slide" in the bearing/hub assembly. Now whether its to turn the sensor, allow for movement while hitting the power, turning or whatever...that spline shaft needs to move in and out of the hub assembly. The splines themselves dry out over the years and the air-gaps and rust, allow the clicking sound to happen.
