E70 X5M Guibo Flex Disc DIY

Gents,

I was milling around under the truck when I noticed a few chunks taken out of my flex disc on the transfer case side. I went ahead and ordered the Febi part and went about the install. Like usual I didn’t intend to make a DIY so I didn't take too many pictures but may go back eventually and add some “posed” photos for better explanation.


Notes: You must remove the exhaust and it is a pain to realign the pipes with the downpipes when putting it all back together. I ended up having to pull the downpipes out, install the exhaust, then reinstall the downpipes. Raising the exhaust back is really a two person job…I messed around with it for an hour then got the wife to help. The manual transmission neutral release for the 2007-2009 trucks are under the cup holder; the release for 2010-2013 is under the vehicle on driver’s side of tranny. Using the manual parking brake over ride caused a code that I had to clear using a scanner. I ordered new bolts and nuts for the drive shaft/t-case connection, but the replacement bolts were too long and would have prevented me from reinstalling the drive shaft. I reused the old bolts and used the new nuts.

STEP 6: Reinstall Heat Shield

a) Reinstall two heat insulating sections using 8mm and 10mm sockets

Thanks for posting this and your other thread with some details on the center support bearing.

I wish I had searched more thoroughly and found your center support bearing thread before trying to take on the job on my 35d. I have all the heat shields off and realized the driveshaft is not the same as all the other BMW videos online (Large nut on rear diff versus multiple bolts on older cars and more importantly no bolt to separate the driveshaft).

Both my center support bearing and guibo look ok with flaking but no tearing at 106k miles. I'll probably still do the guibo since the heat shields are off and I have the part, but I doubt it was causing the vibration that I was chasing during high torque low rpm situations. I'm starting to think it could just be my aftermarket ATM midpipe hitting somewhere, which I will be putting back on in the next few hours anyway so we will see if I can fix it.

Edit: It looks like there is a solution for the center support bearing that doesnt require dropping/separating the driveshaft, not cheap but much less labor. It addresses the rubber surround which is usually the failure point, and reuses bearing itself.
