Also Arron on my drive shaft and a few others I know about you put it in one way and it will run out big time. Unbolt it and turn it 180 degrees and it runs totally true. Don't ask me how. But its true. All you might of had to do is rotate your driveshaft 180. Did you try that first? Lol!

Hey Rick. I did not rotate it 180. Just took it to the driveline shop. Had the driveshaft checked and they confirmed my runout issue with the driveshaft. Took the replacement DS to the same shop and had it checked and put new ujoints in it. They run it up to about 130 mph to check the balance. It balanced out perfect. I will keep the old one as a spare, just in case.
