REAR DIFF removal instructions
 

Going to replace humming and backlashing 2012 A4 B8 100K rear diff with a 2014 A4 B8 diff with 7K.

Would anyone have instructions on the removal/replacement process ?

As usual, these straightforward-seeming jobs are probably not !

Thank you.

This is a very uncommon job, so it's unlikely you will find much DIY help. I suggest you download the service manual from the erWin site. For a $35 one day subscription you can download all the pdf modules for your car.

You are absolutely right. I should get the PDFs.

I do like personal experience stories as well !

Thank you
