Changing Halfshaft U-Joints
1984 Corvette - If I take the halfshafts out to change u joints is there any marking needed? I mean do I need to mark left or right, or inside/outside on each shaft or are they completely universal and it doesn't matter?

If you haven't bought the u-joints yet, try to get the spicer parts, Napa sells them, the zerks are located on the end caps and not in the valleys... Better design by far..........

Racers at the track (SCCA) always mark them so they go back exacly the same way they were on the car.
Why?
There's always a certain amount of twist in the shafts from running them hard, not that you can see it. This weakens them somewhat, so if they're flipped they'll fail.
