    Default Crunching noise on bumps

    Anyone got any ideas on this one: I have a 2004 vectra sri v6 cdti, when I go over bumps where the weight of the car lifts then comes back down I get a cruching noise. I have been to vauxhall 5 times and they keep doing work under warranty and not fixing it. I was even told by one chimp at Llangefni Slaters Vauxhall it was the boot lid even though I can feel the crunch by my feet!!!

    Possibly the anti roll bar bushes, or maybe the radiator mounts?

    Had the radiator mounts replaced, I thought maybe the coil springs??? Had the anti roll bar bushes checked and they were fine??

    Has it had the spring seat mod done to it??.. the cruching is usually cured by this..the mod sleeves the end of the coil spring that sits in the spring pan in a nylon tube..

    Not sure about that but I willcertainly be enquiring if it has, what should I ask the dealer if it has had, presumably they will know if it has or hasn't been done.

    just ask them if it has had the mod done.. they will be able to tell without even taking the wheels off...

    I'm pretty sure its the anti-roll bar bushes, mine does the same when its cold, but quiet when warmed up.

    Talking Both of my Vectra's

    Hi, I'm addicted to Vectra's. The latest being my lovely 2002 2.2DTi Elite...
    I thought that moving up to this model would have seen the grating noise disappear, as i've had it on both of my previous 'B' models. Alas, not so, it's back with this one. Only on the cold mornings though. I'd say it's a common problem throughout the Vectra family.

    Not much help i know, but your not alone......
