I have a slight gear lube leak coming from the axle drive flange on my Tiptronic (2001 Boxster S). Need technical advice on axle drive flange removal so I can replace the seal. It appears from the differential diagram that the splined axle drive flange is held in by a small wire ‘C-ring’. Question: does the axle flange just pop out when evenly pried out from the case, or is there a special removal process? Also, should the C-ring be replaced? Thanks for the assistance.
