Default Rear diff proper level

i've recently replaced fluid on mine 1995, and added fluid till oil starts dripping out from filling hole thinking that is right procedure


though i've just read on chilton's manual that level should be about 10mm above filling hole...?

Any suggestion, you know is right?

Also seems (always on chilton's readed) that there is a drain plug on rear diff and this is the bolt in the center of the bottom rear plate placed. (I've used syphon pump to suck out old fluid)

You've done it correctly. If the car is "straight and level" you're fine. If the rear is 3ft higher than the front axle then you've likely got issues.

You don't have a FSM for your car?
