3. Which side of prop shaft is better to marry with oem prop shaft?

4. how to remove oem sideshafts w/o special BMW tool?

Anything else/special like list of needed parts or so that we have to know/have before installation?

Would be really appreciated
I'll give it a shot:

1. I always replace sideshaft bolts as I have snapped them on my older BMWs. For the 6 bolts that attach to the sideshaft to the diff, I always tap the socket onto the bolts with a hammer to prevent them slipping. For the sake of a couple of Euros, why risk it? Also make sure you use m3 sideshaft bolts as they are different to the 135/335i ones. I bought brand new driveshaft to diff bolts as I didn't have them and replaced just the nuts on the gearbox side.

2. Buy a bentley manual as it should have the torque specs you require.

3. As far as I know, either side will work. I used the m3 driveshaft and shortened it from the transmission end as it was easier in my eyes to measure.

4. You need an E14 socket IIRC and a 36mm 12 point socket to remove the sideshafts. Both are pretty standard tools on BMWs. I would be more concerned about removing the driveshaft. I would highly recommend purchasing the AR Design spanner as it is perfect for the job and can be sold on after you use it.
