Vauxhall Astra wheel judder

Easiest things to check first would be wheels and tyres for buckles , twists or bulges .Could try rear wheels to front and see if any different .Also check engine , trans mountings and steering , susp. arms / bushes for wear .

all tyres an bearings been checked an no problems still get problem engine is fine no warning lights car ok to drive at 50 mph but once go faster you get the judder

Hi try changing the wheels round. It mite not of been balanced right.

Well I can tell you this,
they do not balance tyres at any thing like 50mph!
Single figure speeds are more like.
So it might be high speed tyre distortion.
But that would only help if it could be narrowed down to which wheel was the culprit.
But you do only have 4,
so fit the spare and road test,
if no change then move the wheel to another corner and re test.
If there's no change after fitting the spare to each corner then it is NOT the road wheels.
The only other source would be a warped disk.
And I have my doubts that the guy who tested the disk used a dial test indicator.
Just eyeballing it isn't good enough.

You getting any judder through pedal when brakes applied ?

no only getting it at high speed through drivers side front wheel an steering wheel ?

Wheel bearings spring to mind here.
