OK, so I'm read up! How do I know if I have an open differential, or a LSD???

 

this option was standard on the zr2 trim,,,,,,,,,, just a little tidbit!

 

mine's not a zr2! also is it posible to have an open differenial in the back, and a LDS in the front???

 

no you do not have a limited slip differential in the front. i can tell you that for sure. the reason why the it binds in 4WD is because TWO of the tires (one in front and one in back) HAVE to be moving at the same speed, and when you turn they are all moving at a little different speeds. i can see where you would think "well if i have an open diff then why cant the tires spin at different speeds without binding and two tires slipping?" but no thats not how it works, when you turn sharp the inside tires travel slower to make the same turn as the outside tires. so one of the tires on the inside has to slip to be able to turn at the same speed as the outside tire. thats not always how it works tho, the two inside tires could be getting the power but they will still move at slightly different speeds causing one to slip, all depends on which one has the least amount of traction.

This isnt the easiest topic to explain but hopefully i didnt confuse you anymore than you already are. but all in all DO NOT drive on dry pavement or high traction surfaces with your truck in 4WD

 

As I stated above, there was NO OPTION for anything other than an open diff in the front. The only factory option for the rear was the G80 Gov-Lock rear diff which you have already stated you do not have. And if someone has changed it out (which your observations of 1 wheel peels follows that you have a standard open rear diff), the only way to tell is by removing the rear diff cover.

Now please try to read & comprehend the information that you have been given. It doesn't appear that the second part of that has been happening.
