How often gear oil should be changed - Testing Autos

You must have a 4 Wheel-drive. You should have a driveshaft for that end of the vehicle and you should not let the Mechanic keep it. The rear unit must have a bad Pinion bearing or more damaged parts. Some of parts can "freewheel" without having power going through them.

But the metal shavings from broken parts can travel inside the differential and cause more problems. You don't always need the 4-wheel drive function and you do not have it since the Mechanic disconnected it.

Sometimes it can be what is called an "axle" bearing. Each side has this part so you have 2. The noise levels for this part can also change when the 4 wheel drive is engaged.

Make sure the rear differential has lube. Read the Web for articles about your vehicle. Search "2003 Ford Escape rear differential".

There is a Salvage yard site called Car-parts.com which is good for locating used parts like differentials. One would need to match the same gear ratio as the front.

Are all the tires the same size?

are they locking up going straight or turning?

did this start before or after you replaced the rear diff?

if after does the rear diff have the same gear ratio?

There is a drain plug and a upper fill plug on the front differential, and believe it's in the passenger side. but i could be wrong on the side. The age thing but you can see both of the plug than you need to drain and re-fill.

The term 'Rear End' when used with a vehicle, is a slang term for Rear Differential. Your engine turns the transmission, which in turn turns a driveshaft, finally turning the rear differential. The gears inside the differential turn axles, and your rear wheels are connected to these axles.

The rear differential, has Nothing to do with why your transmission won't shift. Manual or Automatic. I suggest you find a competent shop, and leave That One Alone!

Yes this can be fixed. Sounds like your spider gears have decided to cause you problems. If you can't do the repairs yourself take it to a good gear shop. They can replace the shims and or bearings. Do not attempt this if you know nothing about setting up gears. Don't waste your money by purchasing a used differential. Like I said a good gear shop can do this for you. Shouldn't cost to much.
