I am replacing the u-joints in my '72 FJ40 and have read that it is important to mark the yokes and driveshafts before dismantling. So I did.
However, now that I have everything dismantled and I'm looking at the yokes/shafts/etc, I don't see why marking up the parts is important. All the parts look symmetrical - i.e. it doesn't appear like it matters how the yokes are reinstalled.
Can someone explain what would happen if I don't reinstall the parts exactly as they were before I removed them from the shaft?
