hmm, whilst there is mention of circlips, it appears only relevant to dismantling the driveshafts AFTER their removal. but not relevant to actually removing the driveshafts from the car.
not sure where you're at with the dismantling and visualising how it's designed, but from what i can gather, the setup from left to right goes something like:
L-side driveshaft <> diff <> intermdiate driveshaft <> R-side driveshaft
hence, between the diff and the R-side driveshaft is the intermediate driveshaft. one end of the intermediate driveshaft is connected to the diff and other end to the R-side driveshaft.
to remove the intermediate driveshaft, you first remove the R-side driveshaft, same as you'd remove the L-side driveshaft. once the R-side driveshaft is removed, you can proceed to remove the intermediate driveshaft, which will free up the diff.
to find this info in eLearn, i did a search for 'drive shaft' (title; and searched for 'procedures'). then read about
:
'DRIVE SHAFTS AND JOINTS'
'INTERMEDIATE DRIVE SHAFT - R + R WITH R/H DRIVE SHAFT REMOVED'
they appear bolted together, no circlips. hope this helps!
