A torch is a very useful tool while doing a differential swap. Here, Steve is heating up the tone ring that is responsible for the speedometer reading. A bit of heat and this ring expands enough to simply fall off the original differential housing. Then, if you are quick enough, you can place the heated ring onto the new differential and it will slip right on. Once it cools the tone ring will be solidly mounted on the new carrier.
