Is there any way to check if a car has an LSD besides laying down a strip of rubber?? IE are there any drivability symptoms?? Main reason I'm asking is that ive been noticing that ive noticed that my car grabs really well during acceleration, and as i turn corners at a low speed from a stop, i get a bit of tire squeel. I know my alignment is good (got it done back in february), and I've driven some of my buddies RWD cars with 1.5 way and 2way LSDs and have had the same symptoms. I bought the car with some mods already done to it, and to be honest, I cant remember if the guy mentioned it had an LSD or not.
