No time wasted huh. Enjoy them broGoing to my friend Rick's shop (Ace Transmission in Midwest City OK) to have the ass end gears swapped from 3.73 to 4.10. Going to stop at the local Ford dealer in town and pick up six quarts of 75/140 fluid and two bottles of friction modifier. The fluid in the differential isn't that old, but I am a firm believer in never reusing any fluid, whether it be transmission, engine oil, power steering fluid or differential fluid. If you're going to drain it, replace it.
For how I drive my truck, they'll be fine. Doesn't see much, if any highway use. If so, doesn't exceed 20 to 30 miles. I had 4.10's put in my old Ranger earlier this year. Love it! Much nicer to drive, even on the highway. It also had 3.73's prior to the swap.Your setup is one of the few I wouldn't try and talk out of them.
Nice rant man...Which is exactly what I'm after. And btw, do you think I am the only Lightning owner who doesn't race his truck? Do you think Mike (blowerwhore) Gondek races his? My friend James, his will likely never see a track either. I own mine simply because I love Lightnings. Love the way they look in comparison to every other vehicle out there. And I'm told, every time I drive it, how nice mine is. More than once usually. PRICELESS!
