help needed

i have been clicking noise from my front passenger side wheel sounds like a stone in the tyre tred, it only starts clicking after about 5-10 mins of driving the faster i go the faster the clicking anyone got an idea what it might be before i take to a garage. cheers

CV Joint?
Is it worse on full RH lock?

it just makes the noise when driving at speed, no nocking on full lock from stand still.

Have you checked for nails or a bit of metal ? (can be hard to spot sometimes )

The CV joint is the likely cause here and is the place to check first. Another place to consider is the front knuckle joint on the propshaft. As the engine load increases it twists on its mounts. If the propshaft CV joint is siezed then the movement will be taken by the VC bearings and you will hear that from under the car.
