How do i know if my inner CV joint is Worn??

[golf gti 16valve]

hey ppl,im just wondering if anybody can tell me how i know if my inner cv joint is worn,i get a sort of a whine on full lock at any speed,and i often get a clunk coming from it as well,but its more of a clunk than a Click if you get me,i also get it when im sitting in traffic and when i start to roll foward theres a clunk,im pretty certain its the inner one, ohh and also any idea where and how much roughly i can get the big bumper brackets.. thanks ppl

i think you have to turn it on full lock and move forward if it clunk/clicks like you say it does then yes its possibly knackered.

you should feel a vibration at about 60mph with a worn cv too
