Review on LAFORMO 635 518 12639250 Crankshaft Replacement by Durioki Cordaro

The shaft sealing ring itself was installed upside down during assembly. After a very difficult task of removing the gearbox on the Envoy 06 denali 5.3 4x4 and putting everything back in place, things got even worse. I had to take everything back and find that the gasket on the plate assembly I bought was installed inside out. All I had to do was buy and replace an oil seal. No leaks. Not very happy with the parts received, especially I had to do this work twice.
