Why would the left side output shaft keep leaking after repced 3 timeson 1994 saturn sl2

seal is easy. Bearing requires tear down

Majority of older MONTERO' s are four wheel drives which means you have two more locations of possible Leaks, called output shaft seals. they are located ( from front of vehicle ) one on each side of transmission. left and right side. just follow the C.V. Joint shafts to where they enter transmission . in order to replace seals removal of C.V. SHAFTS is REQUIRED . verify this is where leaks starts at by cleaning area with spray degreaser and wiping area dry. .. secure vehicle with emergency BRAKE ON.. ALSO CHOCK WHEELS TO PREVENT VEHICLE FROM ACCIDENTALLY MOVING. SAFETY IS A PRIORITY !!! ALLOW ENGINE TO IDLE IN PARK. you should be able to view trans where shafts are installed and check for seepage. if you have small leak at idle and no motion imagine when your car is in motion, it probably rains fluid.

My first guess would be the axle shaft has popped out of one side of the transaxle. They can be tough to get in far enough for the lock ring to hold.

On my 97 SL2 it's on the passenger front side near where your left foot would go. You remove the panel as part of the center console and it's behind it

In my 1994 Saturn SL1, there is a grey one under the hood on the driver's side AND one inside the car on the passenger side where the left foot would go


On the passenger side, on the side of the instrument panel, there is another fuse box, the radio fuse is number 10 on mine. The problem is I changed it and the radio still doesn't work.
On a 93 sl2 its in the same fuse box, but is number 19

the fuse panel is next to the passenger's left knee. the cover is held on by velcro and the lay out of the fuses is on the back side of the cover. it is also in the owner's manual in the glove box

Do not know what an INS fuse is but the 90s saturns I owned, 3 of them, had a fuse panel just to the left of the front passenger's left knee. pull open the panel just to the front of the console, it is held on with velcro.

On the SL2 (DOHC), there are two coolant temperature sensors located on the left-hand side of the cylinder head, near the upper coolant hose. On the SL2, the upper sensor with ONE WIRE controls the temperature gauge in the dash. The lower sensor with TWO wires provides input to the computer. They are not interchangeable. Here is a tip you will need a 14mm deep socket or box wrench. The new sensor may require a 13mm socket or wrench, depending on the manufacturer. Good luck and hope this helps. Keep me posted.

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

There are only two paths for oil there. The rear main, and a oil galley plug a little higher up, about 2 o'clock.

Sounds like an output shaft bearing. In the trans. If it is you should hear it mostly in 3rd and 4th gear. Not a cheap repair, but really needs to be fixed.
