The hose coming out of the rear differential is typically the vent hose. Its purpose is to equalize pressure inside the differential as the fluid expands and contracts with temperature changes, preventing leaks and maintaining proper lubrication. If this hose is damaged or blocked, it can lead to pressure buildup, which may cause seals to fail or fluid to leak out. Regular inspection of the hose can help ensure the differential operates efficiently.
I believe it's the rear differential vent hose.
It may be your differential or your whole rear end or it could just be a worn out gasket.
On a 2004 Ford Expedition , 4x4 : The front differential has a tube ( hose ) coming off the top of the differential ( the biggest part of the case where the gears are )
It is a vent for the rear diff. Attach it high up anywhere so water can't get into it.
That is the axle vent hose. It ties off to the body above the axle.
Fluid level too high, water in fluid, axle overheating.
As far as I know that is a vent hose and it just goes in an upward direction somewhere where it won't get damaged
That hose is the differential vent hose. It is held onto the chassis up under the motor by a small clip. The hose does not attach to anything other than the differential.
rear differential got lube? rear wheel bearings?
If its coming from the rear differential, add some additive, available from chevy.
The low side service port is located on the suction hose coming off the rear of the a/c compressor and the high side is located on the discharge hose coming from the condenser.......
All Ford Rangers have a rear differential , and if they are 4X4 equipped , a front differential also
