No rubbing.

No rubbing, if you remove the heat shield.
Or you revisited your initial install and are now running the heat shield?

So this DS will rub on something or it won't?

Did your revised, shortened driveshaft allow you to install without loosening the diff?

Yes.

Haven't reinstalled it, car has been in the garage for months. I'm guessing the diff still has to be loosened.

Altaran's worked fine, I got mine re-shortened to the proper length, just haven't reinstalled it yet. I haven't driven my E46 in 3 months so once I get it back on the road I'll resume testing.

Installation went well, it really was a breeze. Could not be happier with my decision to opt for the telescoping slip-on joint flange, it was so easy to get the driveshaft into place. Everything else was very straight forward, typical driveshaft job. Only thing that's different is I decided to leave the heat shield off-- a quick fitment check revealed that it's going to be a choice between constant rubbing on the driveshaft being that it's got a larger diameter than stock or an occassional rattle against the exhaust and I wanted to deal with neither of those.

As far as driving impressions go, I can't pretend the car feels night-and-day different, it really doesn't 😂 but I am happy to have rid myself of and never have to worry about the center support bearing ever again. Was a fun project, I recommend to anyone who is looking for something to do to their E46, especially if their CSB is giving issues.

You can't tell any difference in engagement?

Yes, I think they would. Ask for Rob at Nassau Driveshaft located at 2279 Babylon Turnpike, Merrick, NY 11566, tell him John sent you.

Awesome! Thank you!!!

Seems like this should be simple for any competent shop now with this version, no? Hopefully so, I just ordered one and would prefer not to send it off again

Awesome post! Thank you for all the data. Would the shop you used do this for us if we shipped them the DS and parts?

Yes, I think they would. Ask for Rob at Nassau Driveshaft located at 2279 Babylon Turnpike, Merrick, NY 11566, tell him John sent you.

I keep finding part # 7632 and hopefully this works as well

$480 would make this worth it.
