my mrs astra literally from nothing started to really wobble through the steering wheel and also was making knocking noises, had it up in the air yesterday and saw that one of the anti roll bar brackets had come off so have replaced it with a new one only to find the problem still there, have got it in the air again and can see nothing wrong at all, no loose bolts etc. cant see any perished rubbers so im completely at a blank as to what it could be. even the wheel weights are still on.

im desperate for help as my mrs needs car to work

 

Tyres perhaps, unever wear or something especially if the roll bars been loose?

its done about 3 miles since i noticed the noise if that. has to be something more than that

 

sounds daft but the wheels aren't buckled or loose are they? Noone tried to have the wheels off it??

Does it wobble constantly or just at certain speeds?

 

its at certain speeds, not when you first pull away but shortly afterwards its there

 

check suspension mounts and bushes also check the rubber at the top of the struts for movement

 

does it go in time with the rotation of the wheel ie get faster as you pick up speed? What are the driveshafts like??

 

the roll bar may have become bent if one of the brackets came off also it may be the steering rack internals shafted had the same problem with me old vectra every time i drove over a bump or smaller it nearly through me into a verge

 

Check to see if one of the front brakes is binding, what mk astra is it ?

wheel weights dont have to missing for the wheels to be out of balance my focus had a wobble at certain speeds balanced the wheels prob gone one on the front was a bit buckled but balancing took it out
