Signed up for 24hrs on bmwtis.com to see if I could access some info on the blue /yellow dots and special bolts but the whole site us a mystery to me!
If anyone has any suggestions on how to look up the info or once I log out then could do a bit of digging under my password? |

Worked it all out! If you don't use internet explorer you cant see some of the options!
You lads might want to take a look at what I found - I had to "prtscrn" each little portion and piece them together in MSword! Here's the dropbox link... https://dl.dropbox.com/u/96878692/di...0prop%202.docx Explains all! |

I don't think that will happen.all the after market LSD vendors cringe when they see this topic. They the ones that created the challenge originally that it cannot be done.

I'll hit up the BMW tis when I get in - the torque values were just one click away from those instructions above.
Anything else anyone want me to try and find while I'm still on my 24hrq registration ? |

Hey
Didn't get back in time before my 24hr pass was up! Found this page on the free, but limited TIS: http://tis.spaghetticoder.org/s/view.pl?2/51/03 Its all the torque values for the propshafts in BMW models. I'll try and find if there's some mention of any off the other values we need for the diff side. Found this too... possibly less useful? http://tis.spaghetticoder.org/s/view.pl?2/51/04 Last edited by Nigelo; 12-09-2012 at 03:10 PM.. |

UPDATE I guess I know to torque bolts to a certain NM then to turn it for example 90 degrees additionally. Just one question can same bolts be reused second time? Last edited by RimasRS; 12-10-2012 at 09:58 AM.. |

GeorgeSmooth, when you get a chance (no rush) can you send me a PM with a very brief list of what you needed to get this done (parts, major labor)?
I am HIGHLY considering doing this, since I am now single turbo and need to upgrade my axles and get an LSD. This seems like it would be a much cheaper option that may provide the necessary strength I need. I know the DS is the pain as you need the front half of the 335 and back half of the M3. I may see if DSS can make me a one piece to eliminate that problem. Thanks in advance.

And I think guys who did conversion used old bolts and still doing well. I think I will use old bolts also just will make sure to use right balance washer (blue dot). And still I need to find somewhere correct torque to bolt them (specifically for M3 E92 side shafts and drive shaft) |

I think I'll be reusing mine too!
I need a few new things (hub nuts and a few others) for the install so might pick the brain of the service guy when I'm in. It'll be next week before I'm in though. |

Heard from a BMW tech that they are not reusable.

1. Can we reuse old sideshaft and prop shaft bolts, if not which of them have to be replaced with new ones? 2. Torque specs of sideshaft to diff bolts and torque specs to diff and to gearbox specs (or can we torque by heart) 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 |

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. |

I have them I was thinking to reuse them because they are not ZNS which BMW recommends to replace. What about bolt supports (boomerangs)? I have ordered for now drive shaft bolts (because I also didn't had them) and ordered nuts w/o bolts on gearbox side. Also there is no bentley manual for M3 E92 I can't find it. Few more questions how better to press out sideshafts? Because there is BMW special tool for that or to use simple hammer? Is there some gasket under driveshaft bolts and bolt supports? Like it shows realoem.c*m |
