Replacing Prop shaft UJ's

Hi all I've been on the forum a while but never got round to introducing myself I bought a 2005 td4 freelander early this year and last month was given a 1998 1.8 5 door freelander the 1.8 has a few things that need doing to it but nothing too major one is the fact the old owner took out the propshaft and vcu and chucked them in a skip so I've had to buy second hand props that needed the universal joints changing.
I stupidly forgot to mark the rear diff flange so don't know which way to put it back together will this effect the balance when I put it back together? if it goes the wrong way, I know the flange can only be 180 deg out but will be a pain to have to take the uj apart again after driving. And also there is no marks on IRD/diff as not the original prop will this be a problem?
One more question I noticed some tool marks on the uj mount legs where I assume the previous used a bar to stop shaft from turning not big but there on all the legs especially front prop, just wondering if I have bought some rubbish shafts?

:boom:

What goes bang engine or prop?

Don't worry about it. Propshafts are balanced when they're made, long before they even see a car. As for the marks they could be from a scrapper turning the shaft to get to the bolts or anything. At the end of the day there's only one way you're going to find out, so get on with it.

:scratching_chin:

That's what I thought about the marks. What about the flange I don't think it will be a problem but like you say only one way to find out

Put it on and see how it goes. The idea of marking before removing started after peeps complained they had something wrong (vibrations etc) when refitting props. Thats all. If you put back what you took oft, the same way, then you can rule it out when fault finding. If it's new to you then it doesn't matter.
