Rear differential leaking

[cden]

I took my 02 ford explorer to a mechanic because I noticed some rear diff. fluid leaking out. He said its not the case itself leaking but coming from the passenger side of the case. He he would need to order a new boot and something else? I guess the part is like 10 bucks from the dealer. With labor he wants to charge 150 bucks. How long can I go with this leak? how much fluid does it hold and how do u fill it? He charged me 20 bucks to top it off last week. It seems like a real slow leak just a few drops here and there, but i'm sure it will get worse. Thanks for any info.

this is most likely the cause of your leak.

Just check the bumper for oil spraying up on it when you drive. If it is not their you prob could go awhile

As for filling it up, just look for a fill plug -- usually takes a 3/8" (square head) socket driver.

would you just use a funnel to fill it up?

also do you know its full when it starts to come out of the fill hole?

You can try to squirt it from the bottle but have a pan to catch what runs down. The best way is to use a pump. Also make sure you get full syn. and heavy weight. The proper fill level is going above the fill pug by adding a little more via vent hose opening.
