Can any one advise me where I can find a complete exploded view of an X5 E70 30D 11/2010 rear diff all I can find is just the casing, & maybe some one could point me in the right direction with the possible cause of my problem, when I turn right I get a terrible clunking sound & you can physically see the rear wheels shudder I originally thought it was brakes or cv joints, changed them all to no avail, straight line even up to speed not a problem but when turning right more so horrid. Thanks in advance shuyak
