Had a look at a car today and it had a aftermarket LSD on the back, i couldnt tell what type it was but i could get someone to hold one wheel and turn the other with my hands, it didnt seem to offer much resistance, i thought it would take a fair ammont to break free. And yes it IS a LSD, no doubt.
Just wondering what the resistance between the wheels of a lsd reflect? I would think you would use a setup with less resistance on a loose track say gravel and one with a harder resistance on a tarmac track? But thats just my intuition.
It also had a little clunking noise when doing certain things, not a repeating nose just sounded like it was engaging or something.. or what ever diffs like doing while clunking

It made the nose when i would hold the wheel and turn it from left to right and kind of shake it like that you know? And i heard it a coupple of times when driving, like when i had fot down then off then down again i think. Memorys a bit hazy

Cheers.
