So I've got a loud knocking coming from the front right wheel, seems to mainly happen when accelerating, revving stood still is fine. Does it whatever direction of wheels, quite loud, nothing loose that I can see. HELP!

Ever since I got my 1.6vvt it vibrates when its hot quite heavily I can feel it in the seat and the steering wheel, plus it knocks for a second or so everytime i stop completely or change from d to r and vibration increases also when ac is on I only did 8500 km its brand new. Dealer told me its bad fuel even though I only use 92 octane from trusted stations. any ideas?

Hi,
I've had my 2.0CDT SRI Astra J for about a month now and it is great, but...

I have already developed a knocking clunking noise coming from ( what I think ) is front pasanger side. It can be heard at slowish speed up to 40mph. There is no knocking when turning the steering wheel/pulling off + going over spead bumps doesn't make it any worse.

I have so far tried the following:

1. Rock the car from side to side
2. Push down on the bonet ( top of the struts )
3. Push/Pull the wheels
