ya, thats what it is for the most part. It mimics a true LSD
I know you have to take the diff apart and place between the spider gears and then you take a clip off and the springs press against the gears and prevent slippage
From what I understand it also doesn't require any maintanance
Satan I know you are doing alot of tranny work, have you looked inside the diff at all? Did you notice any special tools that may need to be used to get in?
I would expect to need;
1. Torque Wrench
2. Basice metric tools
3. Rubber mallet
4. Lube of some sort and loctite
