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.

u have to drop the sub frame . meaning the transmission and motor gotta come together. unblot the torque strut located on top of the raditor and motor. unbolt strut towers. unbolt drive axles . use a large screw driver and a hammer and tapp out drive axles (cv joint). unblot subframe (slowly) . unbolt the rear part of subframe first so u can get to steering gear. and remove the shaft from the steering gear. and that should be it. also if doing this without a lot of shop equipment. u are gonna need alot of jack stands and jacks to do this job.

Your rear emergency brakes could be hung up. Especially if a parking valet or someone else parked it recently.

You need to jack up both rear wheels and then put your car into neutral with the motor OFF. If the rear wheels can not be manually turned it is either the emergency brakes, the differential or the transmission.

The emergency brakes require removing the back tires and rotors. If it is still locked, then it is either the differential or the trans. The driveshaft connects the trans to the differential so remove the driveshaft. If the differential turns without the driveshaft, then the trans is locked up. If the differential does not turn the problem is inside the differential.

It sounds like you need to get the auto flashed(computer re programming) I Live in Australia and thats whats happening here,the cars are being returned to the dealer to re programme the trans to correct the shifting faults,you would ask your self why is the oil being replaced or topped up on a new car and Lexus is known for its quality control,and technicians training,you may want to go to a different dealer if youre not getting satisfaction,this will fix your issues

Block the front tires. Break the rear lugs loose. Jack up the rear of the truck at the center if possible. remove the wheels & brake drums. Remove the brake shoes,return springs & all the other hardware. Remove the differential cover & drain oil. If you have a posi the next step sucks. You need to remove the threaded pin from the housing & remove the axle retaining clips. All the while,being carefull of the spring in the posi unit. If no posi,then same procedure,minus the "pucker factor". After the axle is out,take a large flat blade screw driver or pry bar & pop the seal out. Keep in mind the axle bearing is probably gone too , so that's another procedure. Keep it apart,you'll be glad you did.

there is a fill plug on the side of the carrier housing on the nose of it, but if the rear end is noisy it is to late, u have damaged the gears or the bearings or both.
