The interesting thing is it looks like mine only had one bolt from the wear pattern where the bolts should be. Maybe it was missing a few bolts and that one couldnt do the work.
So I noticed the rear metal undercarriage piece is hanging and 5 of the bolts are missing.
The threads for these bolts are mint and there are no broken off bolts. It looks like they vibrated out???
Yes, I just submitted this issue to service.
Anyone else experience this?
