This is my second g37 coupe, this one being awd and I got home with it lastnight from a 4 hour drive and I noticed a little bit of smoke coming from the driver side of the engine bay so I looked under the driver side and saw that my axle boot is loose and it’s leaking fluid all over my pipes. I wondering if anyones had this issue and knows if I need a whole new axle or just a boot and if I should be worried about my diff fluid.
