FORD 4X4 SD WITH LOCKING DIFFERENTIAL?
What years does FORD offer locking differentials on 4X4 SD? Basically, which truck will not get stuck when parked on a 25 degree slope/hill with the driver side of the truck on good asphalt and the passenger side of the truck on 3" of fresh mud from a recent rain.(I have a 2001 4X4 DRW)
Thanks

I think ford offered a LS for most all years from the mid 70s up. The problem is it's a weaker design than it should be. IF you get 50k miles out of one of the OEs, you've done very well. I had mine rebuilt 20k miles ago and it's no where as stiff as it used to be.
My suggestion is have a diff/driveline shop put in something else. Detroit/Eaton are pretty reliable.

Even with a good tight limited slip, what you are asking is tough for it to do. You need a locker (which is what you said, but I don't think it's what you meant). AFAIK, Ford never offered a true locker in their trucks.

First, you should have engaged 4 wheel drive. (If the vehicle has Electronic Shift on the Fly 4 wheel drive you need to verify it is working.)
Second, slowly feed the truck some throttle until you start getting your tires spinning (most likely the side in the mud)
Third, hold that throttle where it is and slowly start applying your brake. The brake will give the spinning tires some resistance, causing some of the torque to get transfered to the stationary tires. Let off on the brake slowly as you start moving. You may have to repeat the process a few times.
In essence, it's a poor man's locker.

Okay now Redford I have heard something similar to what you said before but I think you are going to have to explain the actual workings of your "trick". Because it is just not adding up in my head. It just seems like the simple rule that says "traditional differentials send torque & power to side that has the least amount of traction or resistance due to the fact that differentials allow opposing wheels to turn at different speeds or revolutions, like during a turn for example. Maybe I am mistaken????? But, it seems like since brakes are evenly applied to each wheel then the wheels that are located in the mud will always have the least amount of traction or resistance. Now if you could only brake the wheels that are slipping in the mud it might be a different story. I could be way off base let me know?????
Thanks Redford
