If coming from transmission may not be a real issue. If coming from rear of car, likely a rear brake issue.

Hi and welcome to FixYa!

Yes it can be the oxygen sensor but I strongly suggest that you have a tune up too to correct the issue.

Hope this helps and thank you for using FixYa!

if it continues to do this while you drive, it is a sign of water/coolant in the exhaust due to a cracked head, block or most likely headgasket going out. Deal with this immediately before you need a whole new motor...

It also could be the brake rotor rubbing on the caliper pads as you turn, check the brakes before changing the cvu joint if the pad are worn and don't have much meat left replace them the noise may go away.

The clicking sound is usually a cv joint, have them both checked to see which one it is, if not both of them gone.

might be underneath the intake manifold.
