Thanks - that will surely save me some embarrassment at a future cars and coffee!

Incidentally, I just had to look it up, and it turns out the spelling is 'giubo' and not 'guibo', the inventor being Giunti Boschi. Wonder if we'll ever see that one on Jeopardy.

Are you talking about the front section of the rear driveshaft? I think the OP is asking about the giubo that's at the front differential and not the one at the back of the transmission/transfer case.

e39 touring is correct:


"The front driveshaft splines were not greased from the factory and can be fused into the transfer case. You can't move the front differential enough to remove the driveshaft. You need to separate the transfer case from the transmission."



Drop the front half of the rear driveshaft, slide the transfer case back, then you can remove the front driveshaft. Clean up the splines and closely inspect both the driveshaft and the hub in the transfer case. If there is no visible rounding off of the spline teeth, then your safe to reassemble making sure to pack the joint with plenty of water resistant (think marine grade) grease.

While you're down there don't forget to move the AC evaporator drain which BMW was nice enough to install directly over that ungreased driveshaft/transfer case location.

:iagree:

Thanks guys! I will give it another try as soon as I make some free time.

Cheers,

Ooooops. I stand corrected. I was referencing the front section of the rear. I’ve never had the pleasure of messing with the front shaft.
