I just did mine yesterday.....
I did mine in my driveway. Used to have a DRW
3500 Ram, that was a pain in the arse. .
My rears were wearing even across but wearing
fast because of the Power Edge fueling module
getting lots of use. . and 2nd gear burnouts.
Fronts were wearing the outer edges some. May
be a little under the correct pressure.
I swapped the left front with the left rear,
then the right front with the right rear so
they will continue to rotate in the same
direction. Maybe it's an old "wives' tale"
but I heard the tires could be damaged otherwise.
I had 14,500 miles on em since new (Michelins).
Torque the lug nuts to 130 Ft lbs so you don't
warp the rotors!
