My husband is playing Snowrunner on Xbox.. apparently you start with very few well paved roads and I asked him why he didn’t have a truck with 4×4, he apparently has one with a locking rear differential so I asked the difference (ex.which is best for mud/slush, how can 4×4 have also a locking rear differential etc) and he tried to explain to me but I’m super slow!!
This game is riveting for me…/s.. obviously lol! Honestly learned some neat trucking facts and maybe something about this so!! Not a loss in my books! Thanks for any help!

A locking differential has nothing to do with a vehicle being 4×4 or not. You can easily have a locking diff on a two wheel drive vehicle.
A locking diff locks both drive wheels together so that they turn at the same speed. It is great for traction but bad for going around curves. So you leave it open (unlocked) for normal driving then lock it when you need the extra traction. A “live” axle is like a locked diff, but it is permanently locked (often welded) so that both wheels always turn together.
A standard “open” differential (what most cars have) allows the drive wheels to turn at different speeds. Great for going around curves but not good on a slippery surface because one wheel can spin while the other just sits there doing nothing.
A “limited slip” differential will allow the wheels to turn at different speeds for cornering but will limit how much just one wheel can spin relative to the other.
