Hi folks,

like the title says.. is it possible to install the drive shaft carrier and bearing in a wrong direction? I'm getting some vibrations after my install and am not too sure why..

For W123 - inner V fold of the rubber mount is to point towards the Universal joint.

However - I'm guessing you didn't do the rolling it back and forwards trick before you tightened everything?

(This isn't in the FSM - tis a trick learned by many before)

Don't leave that there - I'll take it to bits!

Could be an alignment issue. I believe the correct procedure is to loosely install and then roll vehicle forward and back to let assembly "settle" in correct location before tightening.
I have followed that procedure to fix vibration after carrier bearing install.
I am not understanding how wrong direction would cause vibration.

If you've removed the driveshaft, you could have it not aligned correctly. There's colored marks to line up the driveshaft from MB. If it isn't balanced, it's going to cause a vibration.

Actually I've done all the things above with the exception of the orientation of the carrier mount.. meaning I'm not sure if its installed backwards. I can't see how this could matter but perhaps it does.

Funny thing is.. I marked my DS when removing it and when I installed it I noticed that it had factory alignment marks. I ignored my marks and aligned it per the factory notches.

Got a TON of vibration from 30mph +

Removed and re-installed with my marks and now have way less vibration but some is still present.

I'm thinking either the DS is messed up in some way OR perhaps I'm getting more vibration because I only replaced the rear flex joint and not the front one.

Thing is I can feel the vibration coming from the rear section of the DS.. not the front where I would presume it was if that flex joint was going bad.

Over time, the universal joint develops a slight notch. When reinstalling the rear portion and carrier, ensure you are set in that notch vertically. (slightly raise and lower the very aft end of the driveshaft and make sure it is smooth.)

If not, then the carrier bearing will need to be removed and re-installed on the driveshaft.

There is only 2 ways it can go on.

#3 is the collar nut which is in front of the Carrier Bearing Assembly and you can tell from the bellows of the Carrier which way the Carrier Bearing Assembly goes.

There are 10 ways to install it, but that's if you use base 2.
