Fords limited slips aren’t known for lasting very long either.....
4x4 basically means all 4 wheels get power. Think of it this way a 4x2 vehicle in reality only has one wheel spinning, a 4x4 has two. All four wheels are getting equivent torque on a 4x4, but often only two will spin. Reason being is an open diff supplies both wheels on a given axle with the same amount of torque that of which the wheel with less traction can receive. So your wheel up in the air is getting x amount of torque and your wheel on the ground is also given that same amount of torque (not enough to roll forward) but it is getting power. So yes a 4x4 is sending equivent power to all 4 wheels, big BUT that is governed by the wheels with the least amount of traction. This is why we perceive only two as erring power but in reality all four are receiving torque. This is where braking bias or limited slip can assist further to send more power to the wheel with more traction. It gets confusing.
Now a locking differential locks the speed of the wheels on a given axle. Note to do this different torque must be applied to the different wheels as they have differing amounts of traction. So a locking diff supplies different torque to each wheel to lock the speed (hence we see both spin in tandem). The locking diff will send more torque to the wheel with traction while sending less to the wheel without (now it’s locked).
In this situation an open diff is sending the same amount of torque to both wheels. Say wheel x is in mud and wheel y is on pavement both wheels will receive the torque of wheel x with less traction. Now on a braking bias system wheel x will have the brakes clamped changing the perceived resistance forcing more power to wheel y (this is how they get around the issues of a conventional open diff).
Thanks & yes Stock Vehicles. I'll have to study up on "differential" and "limited slip". I'm still learning.
I think that was his point sort of, but if one wheel stops turning at all ... which does seem to happen ... some potential traction being lost I think. Obviously I know squat though.
