Here's more video samples, in this test, GT7, force feedback 7(game), 11(wheel), Trueforce 0(wheel), vibrations 0(game).
I'm driving the car on a straight, waving left to right.
1. test = hands resting on the wheel = creaking / clicking noises
2. test = hands pushing upwards = almost silent
Although I first suspected the quick release mechanism to be the culprit I definitely ruled out that possibility by using pliers to rotate the wheel at the hub as mentioned in an earlier post. Also the QR is firmly pushed as far as it can go and the rig itself is a full metal construction. The creaks and clicks come from the wheel, somewhere from the hub assembly, it's very hard to pinpoint the source.
