I was putting Bilstein 0929's on the rear. Stripped the threads on the lower mounting bolt when torquing it down.
I used the FSM spec of 63 ft-lbs. There was no insert with a spec in the Bilstein boxes. Only saftey info in 12 languages...
My thoughts are:
1. Ok, I did torque it a little past 63 ft-lbs. I was going after the "2nd click" b/c I had a small extension on the torque wrench and didn't like the angularity and "twist" I felt. But, I mean, like 1/16th of a turn on the 2nd pass and the thing just gave way. Doesn't seem like the spec should be that close to failure.
2. Maybe my torque wrench is off? I was using a smaller one up near the high end of its range.
3. Specs for the Bilstein's are different that OEM shocks. (Doesn't makes sense, since they are exactly the same size fastener...).
BTW, the bolt and nut were definitely clean and dry. It isn't like I had oiled it up, so that I was "fooling" the torque wrench.
Anyway, experts please enlighten me. This was an expensive mistake.
P.S. Any fix aside from purchasing a new shock?
