[Vwdiesel] 'EJ's Yo Yo Caddy

[mark SHEPHERD]

IMHO its unlikely to be a fault with your CV joints in my limited experience their faults show up as a grinding or knocking..try driving in a circle full lock both ways this will usually display a clicking or grinding..driving in a straight line puts minimal stress on the joint so if it is the problem then the joint wear will be felt through the steering moreso on the circling.
I put my money on a tyre perhaps with a slight flat spot.. and maybe coupled with a weak shocker...[do the bouncing of the vehicle corners test]..
Maybe do a spin of each wheel [jacked up] and gently stroke it to feel for anomalies as it spins
