My 1995 Ford Explorer Owner Guide shows :
Motorcraft Premium Rear Axle Lubricant / Ford Part Number XY-80W90-QL /
Ford Specification WSP-M2C197-A ( 5.5 pints )
( and if you have a Traction-Lok rear axle to add 2 ounces / 118 ml of friction modifier , but 118 ml is around ( 4 ounces )
on top of the rear differential

On a 1995 Ford Explorer : According to my owners manual : Rear differential ( 5.5 U.S. pints ) plus ( 4 ounces of friction modifier if it is a Ford Traction-Lok ) of Motorcraft Premium Rear Axle Lubricant
On a 1998 Ford Explorer ( same as my 1995 ) Ford calls the smallrear shock absorber that runs on an angle the ( rear axle differential shock absorberor lateral shock ) As far as I can figure it is used to stabilize the rear differential ( P.S. I'm not a mechanic / technician )
Between the two rear wheels where the driveshaft connects ( some people call it the " pumpkin " )
3.55 look for metal plate on one of the sides of the differential
There is just a rear one I believe, on top of differential
According to the owners manual - Motorcraft SAE 80 W - 90 Premium Rear Axle Lubricant in the front ( and rear ) differentials on a 2000 Ford Explorer
All Ford Rangers have a rear differential , and if they are 4X4 equipped , a front differential also
I believe it's the rear differential vent hose.
90w ======================================================== According to the 1996 Ford Explorer Owner Guide ( 80W90 ) for the REAR differential * if you have a Ford Traction-Lok add 4 ounces of friction modifier
i HAVE A 2003 FORD EXPLORER, WITH LESS THAN 15000 MILES THE REAR END STARTED WHINING FOUND OUT FORD HAD A BULLETIN ON IT , THEY REPLACED THE WHOLE REAREND.
