i have started to get a shudder when i put my foot down happens mainly in 3rd 4th and 5th

its not the same as the balance being out and u getting a shudder at 80 or 90mph the whole front end of the car rocks from side to side

u can feel a funny bounce as well at about 50 as if a tyre has a bubble
