Hi group, I want to change the differential fluid but depending of my gear ratio is the oil that I have to use, but I don't know how to find my gear ratio, so please any help is very welcome. Thanks in advance..
 
Should be listed on the build sheet. Another tell is engine rpm, a 3.92 at 2000 rpm will be going 70 mph in 8th gear. The 3.21 will be around 1500-1700
 

Put in your vin and choose dodge. If there’s a ratio listed under optional equipment, that’s what you have. Otherwise look at the standard equipment.
