I am looking at buying an evo 2. Took it for a spin today the car over well was great but I have a question and I hope someone can help me out. The car has a cusco 1 way mz lsd installed in the rear. I dont know much about lsd's and have been reading up on them. One thing I can't seem to find is if the 1 way should make a loud knocking noise at low speed only on decell and usually while turning. I did notice that the inside tire will kinda skip or hop, from what I know this hop or skip is normal. Should there be a loud knocking or clicking noise while turning at low speeds? Thanks for the help everyone!

 

I have read this is the clutch type LSD could this mean the clutch plates are worn out?
