Here's a quick diy for anyone wanting to swap out their rear.
First let me start by saying in my opinion after running the 3.70 at the track and after having the 3.09. I personally went back to the 3.09. The 3.70 is great for around town fun , a quick boost in acceleration for a stock set up car. As far as the track , imo, it's just too much gear. It shifts too fast and caused me excessive wheel hop in second gear. Yes second. I launched pretty good in first , consistently at a 1.7 60ft , but hitting second just hopped and skip shift right to third. Any way for me , I think 3.09 is better. I'll get back about that after ATCO.
Now for the guys coming from a 2.62 open or lsd, the 3.09 is an ideal gear for the heavily modified 5.7 or the hellcat. A 3.70 or 3.90 may be beneficial to the mildly modified 5.7's looking for a good kick in the a$$. Again this is just my opinion.
This was done by , Bad B-rad and myself. So shout out to Brad!!
First things first, we ran the car in reverse up onto ramps. Disconnected the exhaust to allow for a bit more room. This is on a 6.4 , I believe the 5.7 can disconnect where I circled. There are the two clamps holding it to the mids ,and two bolts at the active valves ,and then two more at the rear. Sorry I forgot to get pics of these , but you'll find them. We found it easier to pull the bolts , rather than slip off the rubber. We also pull the further back body cross member.
Next up is dropping the driveshaft,(I believe it was a t40, but not sure) a mallot will do the trick here also. Then support the rear with a hydraulic jack that can roll when you need to.

Then you have two vertical bolts holding the housing in , remove those.
Now you can begin with an open end 21mm wrench to loosen the two rear horizontal bolts and slowly walk the jack forward to release the bolts( they do not come out as you will see , they hit the tire bin).
Now you can slightly lower the housing and cock it to get the driver's side axle out
Repeat the same procedure for the passenger side
That is it , follow the same in reverse for the install and your off !!!! Good luck!!!!
