Let us know where you’re driving like that so we can steer clear. If you need 4WD for the road conditions, why would you dare drive that fast? It’s bad for the system to drive on dry roads and then you suddenly hit deep snow. Unless there’s ice, snow or mud you shouldn’t be in 4X4 mode as you’ll bind up the drivetrain.I know you should probably be below 50mph to engage 4 wheel drive but is there a speed that would hurt the truck if I’m in 4hi? There were some dry runs and some pretty deep snow covered spots in the highway coming home today and instead of switching back and forth between 2 wheel drive and 4hi I just kept it in 4hi. It got me to wondering if I shouldn’t be doing 65mph+ while in 4hi even though it’s in cleared off spots on the highway. Thoughts?
Thanks in advanced.
