Hey All,

How can I tell if I have a LSD diff in th rear of my 84 Pick up. The previous owner claimes that one was installed. Any Ideas.

Thanks

 

Jack up the rear and spin one rear wheel. If the other wheel spins in the opposite direction no lsd. If the other wheel spins in the same direction lsd. I am not sure if this method will work for you truck but this is how I figured out the same thing on a front wheel drive altima.
