Exclamation 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?

I haven't done much suspension work so I can't help you there, but this is exactly why I don't use a torque wrench. I'd rather use my feel and use torque values only as a guidance, or if none is given, I just use common sense.

Thumbs up

Part 137 in aftermarket are crap from my experience. Threads are off and weaker than OEM.
