What car is this?

Where are these spider joints that should have oil instead of grease? The constant velocity joints take a specific grease. The differential which has spider gears takes gear oil. LSD diffs take specific kinds of gear oil. I can’t think of anything else back there that needs lubrication.

If budget matters, consider good used axles. They can last the life of the car without touching.
