Thanks everyone for your help. I have another question does anyone know what “running ground clearance” is? I went back to the dealer to check minimum ground clearance on all the Xterras on the Nissan dealers lot and found the range to be from 8 15/16” to 9 5/16” mine is right at 9”. The specs indicate there should have 9.9 running ground clearance. Maybe there is a difference between ground clearance and running ground clearance.
