Long story short, my dumb *** got a flat and put the spare on the front drivers side. I just realized that what I did was a no no 5 mins a way from home.
Other than jacking up both front tires and rotating one and looking if the other one spins in the other direction; are there any other ways to tell if i just f*cked up my lsd?

 

put it in gear and try to spin the tires
(of coarse you will need to take out the spark plugs to make it easier to spin)
the wheels shoud both spin in the same direction at the same speed

i am not totally knowledgeable to lsd's so this is the best info i can give you at the moment

 

Just curious, how would putting a spare on mess your lsd? I know its a smaller diameter but that would be just like turning in circles all the time. I've never heard of such messing up an lsd so I'm just curious for future reference.

 

it says in the owners manual not to put the space saver on the front.. but i doubt it would mess it up, just makes it a possibility, and it would be no different than you turning in a circle for 5 minuites... im sure it goes through more abuse in an autocross race than driving with the smaller rim/tire
