just depends on the driving conditions it has seen over that 80k. IMO the video suggests its seen a rough life lol no offense. I lifted my truck at 103,000 miles and the CV boots tore imediatly causing the greese to leak out causing the ball bearing assembly inside to fail. A poping CV isnt the end of the world you can drive on them for quite some time without problems just makes more work if you chose to rebuild them, if you replace with new it matters none. you can check it out by jacking the truck up off of all 4 tires turn the steering wheel hard left or hard right and just rotate the tire by hand listening for pops and clicks and ticks. also check the condition of the CV joint boots on each side of the half shaft's on both sides of the truck. you should hear smooth sounds and no poping should be heard durring this test if you get carnage noise then its the CV joints.
