Good to know! I didn't know they welded some of the spindles in addition to the 4 bolts. I wonder why they would do that.
For mine I just took the drum off, loosened the 4 bolts, put the shims in, and put everything back together.

 

This is on a GE8??

 

Yes. 2010 GE8, 5DR / SPORTN (SAYAMA PLANT)
From the VIN it looks to be early production.
Strange that the Honda parts diagram doesn't show the rear spindles as a separate part.
