I've been expereincing a lot of "creaking" noise in the cab of my truck and in concern, I took it to the dealership to have it checked. Their answer for the noise was, as they called it, the "Flex Body" and there isn't anything they can do about it. Describing it as normal and its due to the cold temperatures. Granted, the only time the creaking occurs is when going over speed bumbs or uneven terrain at slower speeds. Anyone believe this? I've never heard of such a thing. I've googled "Flex Body" and it sure doesn't relate to a truck. (grin) Also, is anyone else expereincing the same noise? I'm about to fire off some complaints but I'd like to be sure first. Thanks in advance for any help!
