Hi Dan (Pageda),
I replaced the coupler on mt 1991 240 in the last few years. Replaced with OEM. (Though using the beefier BMW drop is excellent! For my 1992, soon.)
I did not need to lower the drive shaft, or disengage the center support bearing housing from the body.
Support the transmission body with a bottle nosed hydraulic jack and a short axle stand. Disconnect the transmission mount from the transmission support (flange) at the rear of the M47 II transmission. (Perhaps may have removed the transmission mount to transmission support member retaining nut, perhaps? Leaving the mount hanging on the transmission rear support flange? I forget right now. Can't find the images I recorded.)
Removed the four transmission cross-member to unibody rail retaining flange bolts. And removed the support member from the work space. (A little to and fro articulation to maneuvering of the freed transmission support member from the exhaust header pipe - catalytic converter.) I may have slid the transmission support member rearward along the exhaust piping and support the car right (free) side of the support member with wood blocks.
Mark alignment of the transmission output flange to the drive shaft flange.
Remove the three sets of front drive shaft flange to rubber flex coupler hardware. Be aware that the drive shaft section may come free. After retaining hardware removal, I was able to gently push rearward of the front drive shaft section to free it. There is a center alignment hub that is at the center of the drive shaft front and is proud of the flange that centers on the center hole of the flex coupler. Set the hardware aside. Remember install orientation. Do not mix this drive shaft to flex coupler retaining hardware with the three sets of transmission to flex coupler retaining hardware.
The drive shaft section remains sort of in the way as you cannot move it out of the way. Yet I supported the freed front drive shaft section with another axle stand.
Rotate the old flex coupler to remove the ... okay, you got it. I'm sure. Sorry to go on so.
Hope that helps.
Questions?
Duffed.
