Coming from the drive wheels? Could be worn CV joints
You did not say what kind of vehicle it is. If it is a front wheel drive, it has drive axles and if the drive axle is going out, it will click especially when you turn the wheels.
It could be a broken brake pad binding and grinding. I wouldn't drive it too far without pulling things apart and finding the source.
Clicking means metal on metal and no oil in between. Check your oil, oil and filter changed? Don't drive it if it gets worse - there is a glog somewhere - or it is too late already.
When you drive over a clicking bettle.
You should check the cv joints on your drive line. When they start to go bad they'll start clicking when you turn.
If it's a 4-wheel drive then it could be the axel joint / CV joint. It could also be the brake pads.
Signs of a faulty CV joint are CLICKS coming from the front of the vehicle while performing sharp turns. To really put this to the test, you should drive backwards in tight circles, if you hear any clicking you have a bad CV somewhere you should be able to tell which side of the car it is coming from. Try not to drive very far on a bad CV joint, because you could become stuck out in the middle of nowhere!
If a hard drive is clicking then a person should make a decision to try and back up or recover any files on the hard drive. Files on the hard drive can be recovered by using professional hard drive recovery systems.
Are you talking about the clicking that is heard in the cabin when the turn signal is blinking? That is just an auditory reminder that your blinker is on to hopefully prevent you from leaving it on as you drive down the highway.
A Clicking or grinding noise coming from the front end. The best way to test your CV joints is to drive backwards in a tight circle (wheel completely cranked) you should be able to tell which side the noise is coming from if it is bad.
Could have a bad motor mount
