The rear diff in my powersmoker decided the gearset's life is coming to a close after 300 miles of towing on the weekend(almost 220K on the truck), it's not dead yet, but the howl says it isn't far off.
I managed to score a 4.10 geared 60/10.25 combo out of a 65K mile 97 for cheap(traded a winch for the diffs plus cash, and I had traded a 60 housing I got free for the winch) and I'm going to get at least the rear in this coming weekend.
I have never driven a PSD with 4.10's ever. I'm thinking it'll be fine with my summer 35's and it's going to be much happier towing, but, my winters are 235/85's. I don't want to kill what fuel mileage I do have.
I have a 3.54 R&P I could put in the front, but, I don't have any other long pinion 10.25 gears, just another set of 4.10's. Is the difference in fuel mileage worth buying another set of gears, or not enough that it would pay for itself?
