i cant find out how to fill the rear diffrentual with new oil also how to know when its full

thanks,
Justin

 

The fill plug is on the driverside about 1/2 to 2/3 up on the differential. You use a 3/8" extension on a ratchet to remove it. You fill the carrier up until it is just slightly below the hole. Some people pull the abs sensor on top of the carrier and fill it that way...

 

As soon as the gear oil starts coming out put the plug in....also put in 1 to 2 bottles of friction modifier or you will feel the clutches disengaging every time you turn.....its very irritating.....
