knocking on front end?

[andy_8vastra]

Evening all, gotta rumble which started bout 70mph, now does it 45-50mph and gets worse as speed increases.
Its not a constant knocking only when i seem to go over bumps like something is rattling? shock? wheel bearing?
Feel a knocking on or through footwell too?
I've got a cavalier sri on a k plate by the way and its a 2.0 8v.
Its doing me head in now gotta get it sorted regardless of weather conditions

Any help would be greatly apprieciated!!!!

Funny you mentioned a rattling shock,as i just found the condition on my astra,the big bolt thing that fixes the shock in the strut had come loose.
Causing the strut to basically flex in the middle and would hear the shock hit the inside of the strut,really noticeable when car jacked up and pull puch on the wheel.
I would be thinking wheel bearing though,jack it up and have a play with the road wheel see what you find,mind and use an axle stand for safety
