now I see you talking about supra diffs, does it work well for all of you?

I've one installed in my sierra also with weir performance kit

First diff had too much lock, it was making some noise on turns(clack clack) and the inner tyre felt like with a welded diff. After a few uses it started to loose lock until it had near no lock


then had a replacement diff, installed another new spring from weir performance, and tried to install the adjustin shims not soo tight (just for trying if this was the mistake), also changed the oil to another brand (castrol). First oil was also for LSD.
I don't know what happened but it gave me near no lock, sometimes only one black line on road, and I can lift the car from one side and turn the wheel with not too much force.
Clutches were ok when assembled it.


now I've ordered new clutch discs from Toyota and I'm going to install them again Rear clutch is from first LSD, probably bad shimmed as some of them are
