So I got one of the ball joints installed into the strut housing without any issues. Went to do the other one and got the wedge pin tapped almost flush and then went to tighten the nut and got to 20 foot pounds (spec is 33) before the wedge pin started pulling through. WTF?!
Is it safe to leave it like this? This is a wedge pin from Porsche.  |

The pin is compromised, nothing else.
I'd replace BOTH pins (and nuts!), torque to 16 and use blue loctite on the threaded portion only. NO WAY I'd run the over torqued pins! A failure at this point could cost the entire car and you!!!!!! Loose a pin at 100mph and you won't be able to tell what brand the "ball of metal" is in the junkyard... |
