How can I know if my ST has limited slip (or what?). I'll be changing my rear axle fluid whit Royal Purple synthetic. Are there any difference if I use this oil on differen kind of axle?

Thank you much, in advance, for your answers.

There is a code on the drivers side door on the sticker.



Sticker on the door jam

the code is:

46 — 3.73 non-limited slip

42 — 4.10 non-limited slip

D4 — 3.73 limited slip

D2 — 4.10 limited slip



but if you put a bottle of friction modifier in first then fill with the royal, you will be fine. Would not matter which rear you have...
