2002 Ford Expedition Rear Axle Seal Leak?

Can someone tell me what will happen if I don‘t get it fixed right away Also will this cause squealing in the rear I‘m trying to hold out as long as possible, this holiday emptied my pockets


That depends on the location of the leak. If its at the cover or front pinion seal then the risk is that you run out of gear oil (because of the leak) and without lubrication you can have gear failures and or axle bearing failures in the axle and yes when these parts begin to fail you can get all sorts of sounds from the rear, squealing, or whining or even clunking. If the leak is out the side tubes then the rear brakes can become contaminated with oil (because the gear oil is leaking on to them). Andv these will have to be replaced as well. If I were in your shoes I would remove the rear axle cover and heck the fliud for excessive metal flakes. If there is a lot then expect a costly axle repair, if not then reseal the cover and refill the axle. If you are not repair savvy then a lot of quick oil change places will top off all of your fluids including the axle. Just take it there for an oil change and they will top you off (But I would ask them to make sure they do it or will do it.)

The gear oil will get on the brakes.

You have a warehouse to store them in?

If it is on the pads it will cause grabbing Axle seals are a common failure on the Expedition, Navigator and F-series Just check the fluid level in the rear differential to make sure it is topped off and you will be fine until you can afford the repair! NOTE: the gear oil usually does NOT get on the brake pads because it is open (no drum) and will just leak down the back side of the dust shield!
