Has anyone ever heard about somebody twisting a driveshaft or rear axle shaft due to the increased torque of being in 2LOW?
I remember an old Chevy pickup that I once had had a warning about that in the Owners Manual.
Every truck I've owned with manual hubs has cautioned against engaging 4 low without turning in the hubs.(even in my old Mazda which didn't have enough torque to twist a coat hanger) Never heard of someone breaking the rear driveshaft in 2 low but I suppose it's a possibility. I would think that using common sense and a gentle touch on the fuel pedal while in 2 low would prevent a drivetrain disaster. :)
I really don't see where it would make a difference; would it not be applying the same amount of torque to the rear end components whether or not the front axle is engaged? The Cummins has torque to spare so the rear end will get plenty of torque any time the truck is in low range.
I did this for years with my 2003 F-350 diesel and didn't have any issues. And yes, I am and will continue to be very gentle when using this feature; the Cummins doesn't even need any throttle when backing trailers up, just some gentle releases of the clutch.
