Who knows what the diff ratio is on 2007 g-35 journey sedan auto and if it comes open or limited slip??mine only leaves right tire mark on asphalt

 

i think the rear diff is 3.67 ratio n yes my limited slip also only leaves right tire stripe too but if you take off the t.c and get the rpms hi enought with a slight turn of the front tires both tires should leave marks,, yea baby

 

Jack up the rear, turn one tire, does the other tire turn the SAME direction?

Now chock one rear tire while it's still up in the air, turn the other tire, does it spin easily and freely or is there resistance?

If they turn the same direction and chocked there is resistance then you have factory VLSD.
