Not long ago, I bought an "02 Ram 2500 24-valve Cummins 4X4 from my father's estate.

Is there a quick and easy way to confirm whether the truck does or does not have a limited slip rear end in it?

Thanks,

jack one rear tire off the ground, put transmission in nuetral, and try to turn the tire by hand, if it spins freely, its an open diff

 

you can do that or do a powerslide around a corner or a burnout and see if both tires spin i had one in my 1500 till it broke on me i replaced it with a open diff

 

look in the glove box . there should a label on the glove box door .if its there it will tell everthing about the truck.

 

The glove box label gives a rear end code of 'Dana M70/26'. Any idea what that tells us?

 

that is the size of the rear axle. the front axle should be dana 60. the next line should say limited slip.
