Hi all, Maybe someone could help me? I bought a 1993 Isuzu Trooper LS 3.2 DOHC Automatic.

I removed the driveshaft because I towed it on a tow dolly to get it home, but forgot to mark the flanges on both ends before removing it. I did not take it apart.

Now I don't understand why it would have to be marked if it's a complete unit?

But according to Mitchell On Demand, it must be marked. What happens if you buy a new one? I thought the driveshaft is balanced by it's self? So my question is, how do I put it back without problem?

I thought I could see where it came off from but there is some rust now. Thanks Peter
