I have a 2004 SL55 and just noticed that the rear axle shaft boots are leaking, both inner and outer. I discovered that the outer rubber boot kit is easy to find, PN 2303500037 but i cant find the one for the differential side/inner side. Can someone please help me with the part number for the inner rubber boot? Thanks.
