How do I change the rear differential? - 2000 Jeep Grand Cherokee

On a 2001 Jeep Cherokee Sport (XJ), there are typically two speed sensors: the vehicle speed sensor (VSS) and the rear axle speed sensor. The VSS is located on the transmission or transfer case, while the rear axle speed sensor is located on the rear differential housing. Here are some tips to locate the rear axle speed sensor: 1. Locate the rear differential housing: The rear differential is typically positioned towards the rear of the vehicle, underneath the rear cargo area. Look for the large metal housing connected to the rear axle. 2. Identify the speed sensor: The rear axle speed sensor is usually mounted on the differential housing itself. It will have a wiring harness connected to it. 3. Follow the wiring harness: Trace the wiring harness from the rear axle speed sensor. It will lead you to a connector that is plugged into the vehicle's wiring system. The connector may be located near the rear axle or along the frame. 4. Inspect the differential housing: Look closely at the differential housing for a small protrusion with a threaded hole. This is where the rear axle speed sensor is installed. It may have a retaining bolt securing it in place.

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.

The rear differential warning lamp tells you if the rear differential fluid is too hot. In my case (others) and probably yours case too, it is because the wire connection has become dirty or corroded.

Tools: 180 to 220 grit sandpaper (or dremel with wire brush attachement), flashlight, paper towel. Optional: dielectric grease

Repair directions: slide under vehicle from the back (I didn't need to jack it up at all, you may want to or need to). The differential is the center section of the rear axle. On the top of the differential you will see a single wire connection. Pull the plastic wire connection off the spade. use the paper towel to clean any goo off the spade, then clean it using the sandpaper. Put dielectric grease on the connection (optional). Replace the wire connection. Your problem is solved!

If you have not changed or checked your differential fluids, you should do so. The rear dif uses a very common 80W-90 gear lube, but the front dif uses a rare type that will probably require you get it changed at subaru.

How to Fill a Rear Differential
You may need to add fluid to your differential due to leaks or changing seals, or it may be time to change out the gear oil completely. Either way, it's just a few steps to fill the rear differential and get your vehicle back out on the road!This article will explain how to fill a rear differential. jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderate
Instructions and Things You'll Need:

• 3/8 inch drive ratchet with extension
• 2 quarts gear oil (gear lube, differential fluid)
• Side cutters
• Oil drain pan
• Shop rags
• Flashlight or shop light (optional)
• Lock tight (optional)

Filling a Rear Differential

1. Be sure the car is raised on four jack stands and is level. It will be more difficult to fill the differential if you've only got it raised in the rear.
   
2. Place an oil drain pan underneath the plug to catch any leaks or drips. Keep shop rags handy for any spills.
   
3. Check your service manual for the amount of fluid your differential needs, if you're completely refilling the system. Two quarts should be enough in most cases.
   
4. Remove the spouts on the gear oil containers. Peel off seals, then replace spouts. Use side cutters (or any cutting tool you've got handy) to clip off the top of each spout.
5. Remove the differential fill plug using a 3/8 inch drive ratchet with extension. (Some models may require a hex key or screwdriver, but the 3/8 inch is the most common plug design.)
6. Take the gear oil container and fit the spout into the fill hole. Pour the fluid inside. You can gently squeeze the bottle to speed the process. Repeat with a second bottle if necessary.
7. Fill the differential until the fluid starts draining back out of the hole.
   
8. Clean and replace fill plug. Use lock tight (thread locker) to help seal if desired. You can see my eHow article "How to Replace Rear Differential Fill Plug" (video) for more information.
   
9. Take the car for a drive around the block to get the gear oil moving. When you return, check underneath for any leaks from the fill plug or differential cover.
   

Hope help with this.

no tune up needed until 100000 miles. run a couple of fillups of Shell or Chevron premium gas thru it to clean out fuel system and clean engine. Walmart fuel station also have gas additive you can buy with your gas.

pull the gear cover off the front and on the rear probably the same procedure if the is not a drain plug

It should be listed in the owners manual, but because of different oil cooler setups you may have to do the change yourself and add oil until the correct level is established..... for the first oil change.
Most likely 7 liters,but start with 5,run the engine to fill the oil filter,let it sit for 5 mins and recheck and fill to full.
Note the amount needed for next time.

They were talking about having a locker added too the rear differential. Yes you can have a posi added if I was you I would go with a selectable rear locker, ARB, OX are just to name a few. Any good off road shop can help you withe the parts and install.
