The video is about how to check, diagnose and replace universal joints (u-joints) in a vehicle. The narrator explains the function, location and symptoms of bad u-joints, and shows two methods of removing and installing them using a press or a hammer. He also covers different types of u-joints, how to prep the drive shaft and flange, and how to align and bolt the drive shaft back in. He ends with a test drive to confirm the success of the repair.

Here are some possible facts from the text:
1. Universal joints (u joints) are used to connect the drive shaft to the differential and the transmission or transfer case in most rear-wheel drive, all wheel drive and four-wheel drive vehicles.
2. U joints allow the drive shaft to come in at an angle and to move up and down and side to side with the suspension.
3. U joints have four caps that spin on needle bearings and are protected by rubber boots that prevent dirt and debris from getting in.
4. U joints can wear out over time due to dirt, debris, lack of grease or damage to the rubber boots.
5. Symptoms of a bad u joint include a clunk when changing directions, a rhythmic click, squeak or grind that increases with speed, or a vibration under the seat.
6. To replace a bad u joint, the drive shaft needs to be removed and marked for alignment, the retaining clips need to be removed, and the u joint needs to be pressed or hammered out of the flange and the drive shaft.
7. The new u joint needs to be installed with new retaining clips, greased and settled into place with a hammer.
8. Some u joints have plastic injection instead of retaining clips and need to be heated up with a torch before removing them.
9. The video is sponsored by Advance Auto Parts and shows how to replace u joints using different methods and tools.
