If it’s like a normal limited slip that I have experience with then when one wheel turns the other one will also in the same direction.
‘This may help


It’s not hard to pull a diff cover, if you see clutches then of course it’s LSD, and as far as having two spin marks on the ground, maybe not, remember it’s LIMITED slip, it can still slip unless it’s a Gleason Torsion the amount of power split between the wheels isn’t as much as we would like.

I burnt my clutches out in a 93 Z28 in Germany in 94 by running a space saving spare for a short distance but at higher speeds, that was abuse of course but it didn’t take nearly as long as I would have thought, the different tire sizes caused continual slippage, Factory tires and factory spare.
Miata LSD’s wore prematurely and Mazda dumped the clutches pretty quickly and went with Gleason Torsion diffs.

 

Seems like I've seen more than one or two factory LSD clutch packs wear out fast over the years while browsing the forums.

 

I’d bet lunch that there are a metric ton of worn out packs that the owners know nothing about because if they even know they have it it’s never checked, but average Joe I don’t think has a clue as to what one is or how it works.
It’s surprising how many different types of limited slip diffs there are, many ways to skin that cat

 

Is it possible that failing to use the proper friction modifier in the diff is causing the failure?

 

Possible, but the additive isn’t marketed to prevent wear, it’s marketed to prevent chattering in turns, but as the clutches are “grabby”without it, it’s likely that does mean increased wear.

From memory the Wife’s CTS-V requires two bottles of additive so bigger capacity diffs seem to require more.
