Got a weird one, I'm about to replace my rear shocks with 2X Bilstein B6 4600 (PN 24024211).
The service manual and illustrate parts catalogs both state that the shocks mount to the frame with 2X M8-1.25 X 22mm Flange Bolts (PN 11570082) and Flange Nut (PN 11609746) at 17 [N-m] (13 [lb-ft]).
However, upon inspecting my vehicle, the Flange Bolts are screwed in from the bottom, and weirdly are screwed into threads in the frame rather than through-holes into nuts.
I already have new bolts and nuts on-hand.
I see three options.
1. Attach the new shock the same way as the old shocks, directly into the frames threads.
2. Install the new bolts from the top, screwing them into the frame as best as feasible, then tighten the shocks to the frame via the nuts from the bottom, but this doesn't sit right with me.
3. Drill out the threads with a 10.5mm or 13/32" bit and install per the service manual instructions.
What should I do?
