locking the rear differential
I have a 1995 f250 and rear differential does not lock in when one side spins? Is there something i can do to fix it! Dont know if this helps but it has 3.55s in it!

Axle code 39 would be 3.55 open diff. If the metal tag doesn't have an L between the 3 and the 55, it's open diff. So your choices are a locker as described above, or a limited-slip diff (not as effective) swapped in. Look for a truck with an axle code of C9 (the code for 3.55 LS).
