Instalation went really smooth. Took me a little longer than the 6 hour time frame but I'm an Aircraft mechanic not a auto mechanic. Directions don't have factory torque specs listed so make sure u get either with ur dealership or get an alldata program. I used alldata and it was pretty easy to navigate and get exactly what I needed. There was a small amount of grinding I had to do on my driverside support brace, only about 1"" square, to clear the rear side of the from diff. I used Alpour to make sure I don't get any rust. Drives and rides great no issues at all
