Torque specs questioned for front suspension mount
I am replacing my front suspension guide rod mounts on my 300sdl. As I was torquing the rear bolt, # 134 in the picture attached, to the indicated 80 nm, I felt the torque suddely lighten up with this empty feeling in my stomach. As much as I hated to take it all apart again to see what was going on, I did and what happened is that the aluminum insert inside the large bushing cracked where the bolt goes through.
Did I miss identify the torque spec? 80 nm seemed quite high for this sized bolt but not that unusual. As a comment, it took probably over 120nm to loosen the bolt iinitially.
Ideas?
