Passenger side drive axle u-joint phasing
High all, I'm new to the forum. I bought a 96 F-150 in July and have been fixing it up since. This forum has already been helpful just seeing others solutions to problems, but now I need to actually join and ask a question of my own.
So here's my problem. I started to change the ball joints on my truck this weekend and I got a little ahead of myself when I pulled apart the slip joint on the passenger side drive axle. After doing that, I was looking through the shop manual I have on CD and noticed a warning about marking the shaft to keep the u-joints in phase when you reassemble. I had never thought about it before but it does make sense that u-joints need to be in phase to give smooth rotation.
So what is proper phasing on this shaft? Do I just line up the the U-joints with each other? That's how the drive shaft to the rear diff is. But I've looked around online and apparently some drive shafts aren't phased like that.
Thanks in advance,
Greg
