Ok whenever I turn right and have foot on gas there is a knocking sound but when I have my foot off the gas and turn right it doesn't knock. No matter what it won't knock when I turn left. What could this be?

 

CV. I run race CV's. Porche 930. Basically they are ported and polished and have smaller ***** added. Clickity click clunk clunk is what they do but they flex great and are faster. Poke a hole in your boot and pump in some moly grease if a CV noise is your only problem.
