Tire leaning out Passenger Side
just go to the wrecking yard and pull another power box.
the diff is $450 and something you really don't need, you need a good working box to begin with, not a fast ratio $450 upgrade.
think about what you are driving, don't put the cart before the horse, thats a young person mistake.
let me know if you need some help, we're planing a yard trip soon.
