the rotational play is to be expected, what you're looking for is lateral movement.
from the video the joint seems fine, you could always try to disconnect the driveshaft and play around with the output yoke. same thing on your transfer case (remove the driveshaft and try to wiggle the output shaft and look for any left-right-top-bottom play)
when's the last time you greased your slip yoke? i wasn't aware you had to grease it and it was dry when I first greased it. doesn't hurt to check while you have the driveshaft out.
do you have any lift? if yes, have a t-case drop? SYE? having a lift without any of those could be the source of your problem, like it was said above, because of the driveline angle.
it could be like me and the pinion bearing is on its way out. do you have a rumble type of sound when decelerating too? at highway speed I have an intermittent humming/vibration, it goes away between 40-50mph and it comes back when I let go of the throttle at around 35-40. i've determined it's my pinion bearing even if there is no play at the yoke.
hope it helps

Getting some very minimals wobble when im driving, doesnt matter the speed. The issue is when I start to brake the wobble gets worse the more i brake until a point nad then it just stops when i start to brake harder. Was thinking it was my rotors since I really feel it only while braking. Any ideas?
Thanks in advance

Just rotated my tires. Ill see how it drives now. Everything seemed to be in order. even got it aligned a few weeks ago and was hoping that wouldve solved the issue
Replaced the driver side wheel cylinder, parking brake isn't dragging and everything seems proper but the BRAKE light is illuminated? What gives?
edit: Reefed on the brake pedal and it clicked and reset the system and the light went off. Thanks google

Mine did that a few times, check your reservoir and wheel cylinders for leaks. mine reset 4-5 times and then finally stayed on: leaking drivers side wheel cylinder drained the reservoir over the course of a week. Replaced drum system with a disc system now no problems of that sort! Ha!
If it works, I might have something I can sell.

One reason is when moving shock eye from way below the axle to center of axle tube or on top of leaf springs, there is no room for shock body and extended shaft.
How long does it take, i.e how many miles, to either clear the EV code or have the engine light come on to see what the problem is with the EV system. I drove my 2001 XJ for over 300 miles, but nothing happened. What is the "cycle" for the code to clear?
Before I had a bad front catalytic converter code, but the cat was changed out and the code cleared in a hurry.

I have a loud knocking coming from the oil pan right that started yesterday afternoon. Loud knocking noise on startup, but goes away after a minute of driving or so. Went wheeling on Sunday and the radiator got caked with mud and it was starting to overheat during the 5 minute drive to get it cleared, got around 245-250 before I stopped. Is this a rod knock? If so is there anything I can do besides swap engines?

Hi rcguymike:
Thank you for the feed back. I can reset the code but it will come back unless the problem is eliminated. Right now the EV code is flashing, no engine light on and I drove the car over 300 miles.

What brand of oil filter are you using?
If/when it does it again on start-up, turn it off and wait 10 seconds. Restart it. Noise gone?

I use Mopar filters. I just started it up and now it has an almost rattling sound when I rev it. It warmed up and the rattling went away, but no knock this time
