hi guys hope I'm gonna get some real advice my inner cv cup has a massive play in it.when I drive till about 80km the shudder comes but when over 80 close to 100km it goes away checked all the basics what cann it be

 

If there's slack in the joint itself you need to replace it. It is not worth messing with the boots and internal parts. Swap the whole axle for a rebuilt one.

 

If I take shaft out/off and the cup is alone in diff it has. Massive play in it?
