I'm looking for some opinions on what you think the vibration in the video might be coming from. Dan has been fighting a vibration for the last few races, and can seem to find out what it might be.
The first video is from inside the car, go to 30 seconds to see and here the vibration.
The second video is the camera pointing at the u-joint. You will here a noise when he slows down but it is the brakes not the vibration. Its hard to hear the vibration in this video, but there is allot of movement in the pinion. Not sure that is the reason, but I thought it might be a place to look.
