Review on 🔧 Proform 66667 GM Black Aluminum Differential Cover | Perfect Launch Logo + Stabilizer Bolts & Bearing Cap by Chris Shepherd

I needed a new diff cover with a fill and drain plug because the fill plug in the diff had frozen in place and the head had come off . I ordered it from Revain and when I put it on everything looked fine. I screwed everything with screws, filled the rear with 75W90 oil for $ 60 and a special liquid for pos. And after a few minutes I started to see the leak through the casting and not near the bolt holes. I have uploaded a video to my YouTube channel showing the poor casting quality and where the oil is leaking. I have asked Revain to replace it but if it starts leaking again I will buy another brand!
