What happens here

After lifting the truck, the operator accesses the rear driveshaft. He first removes bolts securing the driveshaft to the differential. Since the driveshaft is a 'press-in' type, it requires force to dislodge. The operator positions a sturdy wooden block (e.g., a 4x4) against the driveshaft. Then, using the wrecker's hydraulic lifting power, he applies controlled upward pressure to the block, leveraging the truck's own weight and the wrecker's force to 'pop' the driveshaft free from its coupling. This controlled application of force is essential to prevent damage to the driveshaft or differential components.

Goal: To prevent damage to the dump truck's transmission during towing, the driveshaft must be disconnected. The operator unbolts the driveshaft and then uses a controlled 'popping' technique with a wooden block and the wrecker's power to disengage it from the differential.

got to do back here, Alec? Uh, this is a pressed-in drive shaft, so I got to pull these off. Okay. And then put a block on here and force it to pop itself out. Mhm. So, you're manually backing the brakes all the way off. Yep. But he was Alec was explaining that you got to have a special tool to really pop that out. But he says good old 4x4s work just as good. He uses the weight of the truck. Yeah, there's a lot of weight, man. So, It took some force to pop that puppy out of there. We need this shaft to stay straight up and down to get it to pop out, but it kept spinning to the side. Straight out. Hey, she shot out the side and turned, Alec.
