Rear Axle Oil Change Question

[Truck#1]

My 98 CH has Eaton rear axles. There are 3 plugs on the rear pumpkin. The top is obviously the fill. There is one not to far below the fill plug and one at the bottom of the housing. Which one do i use to drain the rear end??

Thanks in advance.

The bottom one to drain it.

The middle plug is usually a port to install a sensor for a differential temp. gauge, and if your truck does not have that gauge, then a plug is installed in that hole.

After you drain it, replace the bottom plug and refill with the recommended gear lube until the lube is level with the top hole.

There are no trick questions here, Glenn!!

Here is another though regarding the same Eaton axles. I don't have the model axles they are and I'm going off a 95 CH lube and maintenance manual instead of a 98....that manual says the Eaton rear drive axles take 48 pints of gear oil. Is that per axle housing or as a pair??? 48 pints sounds like alot to me for 1 axle.

thanks gang. you too Glenn.
