87 325is drive shaft removal

First thread in the e30 section woo.

anyways,

Trying to replace my carrier bearing and aparently my guibo too and i for the life of me can not get the driveshaft out. I have un bolted the 4 nuts on the rear of the shaft (to the diff) and the 6 nuts on the guibo removing the 3 bolts i can get out. carrier bearing is un bolted too, now from the looks of it the shaft should collapse or slide in on its self and give you room to drop it out but no such luck.

probably a simple answer but its appretiated nun the less, really want to have the dirty thirty ready for the upcoming auto x and the rally-x after that.

Is there not a threaded nut at the center of the shaft that you can turn with a large wrench? So that shaft may slide inward. Also lower trans suppro bracket a little to give yourself a little more room to move the shaft a bit.

didnt notice the nut but wasnt looking either will go pop back under the car, thanks for the quick response.

ok i see the nut, went a bought a pipe wrench so i had something to fit it, but now that too massive to fit on it and have any room w/o hitting the exhaust...which i cant pull because the PO decided to fit a long tube header and striped one of the bolts holding the 2 pipes onto the header

anyone happen to know what size hand wrench would fit that nut? (googling now)

Guesstimate and buy a bunch, then return the ones you didn't need

i used a giant crescent wrench. but then realized i could turn it by hand

Avoid dis-assembling the prop shaft into two pieces! If you have to do this...first mark the two sections so that you can re-assemble it in exactly the same position...failure to do this can lead to vibration at certain speeds!

i disasembled it (needed to replace the CSB) but marked it first went back to gether fine, cant belive i missed the giant nut ha ha oh well, now she is still vibraating under hard loads at low speeds, if you baby the throllte no issues, i have tried re preloading the bearing so many times i want to shoot myself, so it leads me to belive the the guibo, which is showing some age is the culprate (sp?) guss ill order that tonight and repeat the process, unless you guys have another idea?

Make sure all the u-joints are not binding or have excessive play. Don't forget to re-tighten that center nut as well.

center nut is nice and tight, and ill check the u joints, correct me if im wrong but if they are binding then it is time for a new driveshaft correct?

you can replace them. people have done it. but its a PITA

well hears to hoping its just the guibo
