Hello guys,

Wanna make an oil change for my rear differential (3.23), i have bought the oil 4 hours go (80w90) and i have read on shop manual 1991 i need to put additive lubricant (#1052358), can i use Mopar lubricant ? Here in France it's more easy to find Chrysler/Jeep garage than Chevrolet (real Chevrolet not Ex Daewoo!).

I have read too lot of people broke their bolts when they open the rear axle for changing oil. where can i found this bolts please ? For example this is the bolt ?



and finally how many quantity of 80w90 can i put in my differential ? 1.6 liters ?

thanks a lot for info

Regards

Tof
