Time to drain and replace the fluid. The gear lube does not last long in these rear differentials. Use Valvoline 85-140 weight semi-synthetic. It will slow or even stop the leak and prevent future wear. Only replace the seals if the leak gets bad. Hint: the fill plug is 3/8" socket wrench, the drain is 3/4" socket wrench. Attach a short length of vinyl tubing to bottle to fill the differential.

If it gets on your brake linings the wheel that has the lube leak will lock up on you when you apply the brakes. It will also swell any rubber parts it gets on too. You need to fix it sooner rather than later.

2000 Ford F150 rear differential fluid VANISHING


This is different. In a perfect world, you would run the truck on a dynamometer, get it up to 55 MPH and look under the truck. The fluid is going somewhere.
There is a vent tube on most axles. Follow the tube to find its' end and see if the fluid is traveling away from where you had expected a leak. Check your axle shafts under the rear rotors to see if the Emergency brake drum is oil coated.
Another way to think about this is the original failure. The pinion seal. The seal contacts the rotating flange. If you have a wobble in the driveshaft, (balance issues, U-joints) then the rotating flange can wobble. If you have a bad pinion bearing or carrier bearing, it can work to make the spline gear wobble.
So I am suggesting that the leaking Pinion seal was caused by something and the seal was a casualty of an undetermined cause.
You should be able to add an Ultra-violet dye to the axle fluid to find your leak. Even if it is running from the same place, the current leak will be showing the UV dye.
Please rate my info.

How do remove the rear differential cover on a 2003 Ford Explorer? The gasket is leaking and I want to replace it. The cover is bolted to the frame member and that's alittle


The cover gasket is silicone and is not designed to be serviced without removing the differential assembly.You will need to remove axles , driveshaft , and maybe the spare tire to get differential out.

Fluid leak from left rear axle housing


This is caused by a leaking rear axle seal you will need to pull the left rear axle out and change the seal and check for a worn axle bearing, this requires the removal of the differential cover, pin and center block or posi spring and clutch pack (if so equipped) and spider gears and then the "C" clip that retains the axle into the gear carrier, u will need a tube of silicone to reseal the cover and a axle seal installer tool and about 2 hours of your time

2004 Explorer: Rear differential cover is leaking, how do I fix i...


put flat pan under the housing remove the bolts holding the cover usually 10 or 12 (1/2 or #12 metric) bolts? allow the rear end grease to drain... then scape off the old gasket clean with brake cleaner spray install either new gasket or form one with oil resistant silicone put the cover back on , dont refill the fliud for at least 12 hours if using silicone. Also check the front driveshaft rear end yoke seal....they sometimes leak making the illusion of a rear end pan cover leak...if that is leaking you remove the shaft carefully...remove the large yoke retaining nut, replace the press in seal...be sure retaining yoke nut is properly torqued when reinstalling .

Grease and differential oil inside left rear drum


Not that difficult, raise and support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is (ford 75W-140) (Dana 80W-90)and the capacity is 2.6 liters and 3.5 liters if you have the 10.25 Ring gear. Good luck and hope this helps.

Im slowly leaking differential fluid.


Definitely replace both axle seals at the same time. It will save you time and money in the long run. When the axles are out be sure check for wear on the axles where the bearings make contact.
