Something wrong with my rear end?

Hey everyone. I'm fairly new to rear wheel drives in general, but to my understanding there are conventional differentials and 'posi' differentials. In the chiltons manual it says my car has a "traction lock" rear end. That is probably just fords brand name for a positraction rear end. My question is, when I go around a corner sharp at low speeds (making a U turn for example) and gas it, I hear the tires spin, however the car doesn't "WHIP out" it feels that only one spins. My dads corvette on the other hand would whip out and probably spin out. lol We counted my rear end ratio with rotations of the wheels to axle (or something) and calculated a 3.27 ratio. When the car is jacked up, both wheels spin the same direction when you spin them. Sorry for the "NOOB" question, just trying to become familiar with these cars. Thanks alot for your help
 
'One wheel spin' may be clutch packs going bad. You will get 'one wheel spin' in a turn though and that is normal. Try spinning straight line and see if both tires spin. If they do then no problem.

The similarities between us keep going. You have/had a Probe...I've got one. Your dad has a Vette...my dad has a Vette. :nice:

PS...if the packs are going bad might be a good time to go for 3.73 of 4.10 gears at the same time. You will love it.
