When ever i turn left or right there is this knocking noise coming from the back right of the car and i have a few ideas what it could be. But i need a nother opinion on what it could be.

Try out on a smooth surface ... to eliminate some of the possibilities.
If you see the problem in turns and you have AWD, I would say start by servicing the rear diff.

You get most of the power to wheels front the front.
In turn, the rear diff gets stressed, and that is the reason I mentioned rear diff. If it is locked, then the one wheel ends up skipping.

My advice is worth the money I get ![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
There is a simple test for diff, but we can get to it when you think it is worth pursuing.
If you can add more symptoms may be some one can make a better guess.

Diddo on the differential. If it's been since '06, you need to change the fluid out regardless. It should be relatively easy to do yourself and inexpensive. It might eliminate the knock if it isn't damaged. I'd start there. I change out the differential fluid on my MDX every 30k miles.

X3, go ahead and service the differential. It needs to be done anyways, and we can eliminate that possibility.
Also, I agree it would help if you could describe it more. Because basically, at this point, all we know is that there is some sort of knocking noise, coming from the rear. Not much to go on.
Can you try rocking the car left and right from the back? While doing this can you hear the knocking noise?
