Here we go, letter from my team:
Hey Scotty got some news for you
After inspecting vehicle for structural and mechanical faults/damage, A FAULT has been found in the damaged cv joint. The part is located inside the cv joint, we have sent the faulty part away to 3 different precious metal specialists and have all said the same thing, they have found porosity and burn marks in the metal. The have confirmed damage is NOT from impact but the porosity in the part.
Porosity is caused by two things, 1: is the metal used was of poor quality and 2: is casting temperature was too high for the metal.
This part after casting would have undergone laser finishing of the metal to exact size and specs and be inspected by machine and visually
This part should NOT have passed Mitsubishi quality control and be allowed to be put on to the car, being a moving part this is a big safety concern, but somehow this part has passed probably because of poor quality control and bulk production of the part.
We will inspect the other 3 undamaged cv joints and locate the part we found faulty and if see this comes back with the same result.
This could be a one off part failure by Mitsubishi or a mass production failure.
We are waiting for a full metal analysis report to come back from the 3 precious metal different specialists.
Still working on the rest of the car
Sit tight. Thanks
Edit: this is all of the info i have atm, too busy with work now, ill catch up with this in a few weeks
