5. Add new fluid if necessary.

* Fill with synthetic axle lubricant GM P/N 1237826 (Canadian P/N 10953455).
* For the proper synthetic axle lubricant to limited-slip additive ratio, perform the following:

- For liter containers of lubricant Canadian P/N 10953455, mix in 75 milliliters of limited-slip additive Canadian P/N 992694.
