My GD Elite has the same creaking sound when going over speed hump, and also when taking off or braking. It feels like someting that happens when the body flexes.
The dealership failed to rectify the problem and requested me to monitor it. I have now been back to them to say that there was nothing to monitor as the problem is still there. I have booked it in again for 23rd Oct. Let's see if they can make any progress.
I note the suggestion regarding Silicone, which I have thought of too. But where or at what points do you spray that without messing up other areas.
Has anyone successfully cured the creaking sounds by using Silicone Spray. If so please let me know how and where it was applied.
Thanks...........
