Reinstall drive shaft with no marks on diff flange

[matrophy]

I marked my driveshaft before removing it but one mark must have rubbed off of the diff flange while I was Dremeling off one of the D-bolts that was rounded off.

I'm planning on trying it installed in the 4 different positions and test driving at a range of speeds unless there is some other way of knowing that it is installed back the way it was without doing all of that work.

The position on the diff flange does not matter, as long as it bolts up. If it is a two piece shaft with a pillow block, the phasing in the middle of the shaft matters.

I think the bolt pattern on the differential flange is in a rectangle, so you only have 2 choices. Unless you have a 4x4 with a slip yoke like above it really won't matter.

Well that's good to hear.
