hi new to this forum i have couple of things i am trying to find answer hope you can help
i have a 2006 zafira with 60k and when i start it from cold i get this rattle from the engine area it last for about 3-4 seconds then goes and once the engine has warmed up it does not make the noise as much i have been told could be catalytic converterdoes this seem right.
also when i drive over bumpy roads i get this bobbing noise from the front wheels.
thanks

i would check your oil level the noise on start up might be your tappets. It can take a couple of seconds for the oil to charge them up
