My CV’s click when the car is turning. Is this normal?  I have had professionals tell me conflicting points of view. I have had them replaced already and done professionally, and they still click, quite loudly. I just wanted to get they general consensus from you guys on here, maybe @J Alper will chime in, I always respect his knowledge, and others as well. 
LS1, 2D, 33 Stu sand blasters, and I believe they are 930’s (?) 

Geez, I love this car! I just want to make sure I stay on top of everything and keep her in the best shape possible. Thanks in  advance.

Hard to tell from the pics, have you figured out the degrees the axels are “swept” back? Is the noise consistent while turning both under power and off?

Pretty sure it’s consistent both under power and off the power.

What grease was used and how many trips since the last prep?

2 days of riding since last prep, which included new cv’s and grease. 

 
How long have the limit straps been on that car? They do stretch over time.

^^^ This. When you turn, your suspension tops out on one side (body roll) causing your CV to click. Shorten your straps or buy new ones if they are stretched.

 
There are so many reasons why they click and make noise , I have a Mid travel manx and they will click and make so much noise people will pull along side of me and tell me that I have a CV going out, the reason mine make so much clacking is that mine have a large back sweep, I went 8 years on a set of german 930 before I decided to replace them,and never broke one. I also remove them every year , clean them, and repack them. They are a little louder when I am turning at low speeds. I also put much more miles on my car because it street legal and get to drive it year round. I believe if you maintain them every year,that will be the ticket.

 
I have clocked and not clocked CV's really could never tell a difference some people swear by it and others not so much, for me don't think it matters just my .02 

 
I had a sandcar specialities car that would click if I did not clock the cv's. It was running between 22°-23° without factoring the back sweep. I also had to have kartek back cut the star for more travel.

Mabe the drive axle is tapping the face of the stub, I always figured with the cv not under load it’s sagging towards the hub bouncing back.I always have to file the hub side to get the CV off.

Indexing CVs, aka clocking. It is myth and serives no purpose other than fodder for this website. I prep 20 sets of CVs a year and have never clocked/indexed and set.

Ayep. They’re called Constant Velocity for a reason: they’re self-canceling when run at an angle (within reason). Clocking/indexing is required for U-joints because they don’t self-cancel. Assemble them correctly and throw them on the axle. 

 
My experience is if they are making noise you will soon have a problem.  I second the limit strap question.  Jack up the back end off the ground and rotate the drive wheels.  If the are clicking try a shorter strap.   

 
For argument sake have you ever worked on a car where  at full droop the axle bind while turning the wheel?  Specifically six times in one rotation?

just asking yes or no?  Have you ever been on a dyno and seen the axle have a cyclical back and forth?  Specifically a frequency of 6 times a revelation ?
