Is it to generate heat from the friction of the bones rubbing together or the body trying not to shut down completely. It takes energy to shiver and surely in desperate times that energy is needed to keep warm.

The metabolism of energy stored in the body, such as seen in the contraction of muscles generates heat as a side product. The process of shivering is a quick contraction and relaxing of muscles (faster than we can do conciously) that generates heat as part of the process.

The reasons mammals shiver is because the muscles twitching causes them to heat, thus warming the body up. Teeth "chattering" causes the same response. Also their hairs will trap warm air close to the skin.

The reason mammals shiver is for temperature elevation. In cold-exposed adult humans(or any other mammal), significant or lethal decreases in body temperature are delayed by reducing heat loss via peripheral vasoconstriction and by increasing rates of heat production via shivering thermogenesis. This brief review focuses on the mechanisms of fuel selection responsible for sustaining long-term shivering thermogenesis. It provides evidence to explain large discrepancies in fuel selection measurements among shivering studies, and it proposes links between choices in fuel selection mechanism and human survival in the cold. Over the last decades, a number of studies have quantified the contributions of carbohydrate (CHO) and lipid to total heat generation.

You're partly right, the vibration of molecules produces heat. It's the muscles that you're vibrating though, trading a little energy for a burst of heat. It's one of the emergency methods of keeping the body at the correct temperature.
Obviously, it is using up energy, so it's not a perfect solution. It's an emergency function.

Shivering makes your body warmer.

When muscles work they create heat - that's why you sweat - so when you're cold your body makes the muscles work to warm you up.

its the body trying to keep warm.

It is, simply put, the body's natural way to generate warmth.
