Got everything installed and I'm putting the diff back up. I can't seem to figure out if you're supposed to re-use the upper tapered washer between the front diff ears and the subframe. I'm guessing you do. Or is the top rubber part of the bushing just supposed to sit directly against the subframe?

 

I too could use an answer to this question................

 

I couldn't get an answer from Z1, so I just reused the washers. I don't have any vibrations as of yet.
