No, the front ratio has always been different. The earlier post has the correct ratios in it.

Yes, sort of. Jack up one wheel and put the truck in neutral. If you can spin the wheel by hand, then your LS is worn out. They aren't that hard to rebuild yourself.

The Ford Shop Manual says to place the truck in neutral and block the front wheels and jack up one of the rear wheels. There is a special attachment that goes to two of the lug nuts and has a bar in the middle of the wheel and allows a torque wrench to be placed in the middle of the wheel. If the torque to turn the wheel that is up in the air is more than 20 foot pounds-the limited slip is working correctly.

My 110k mile limited slip is still within this specification!! And I can still climb my snow covered driveway that is on a steep hill in two wheel drive without one rear wheel spinning!! My Jeep has an open rear end and it cant climb the same driveway when it is covered in snow.

I don't see why not. I have also noticed that on a new limited slip-if the transmission is in neutral and one wheel is in the air and you just grip the tire with both hands-you shouldnt be able to turn the tire easily.
