Generally, you would remove the rear diff inspection cover to drain the housing. Once drainer, you would clean of the old gasket or sealer, install a new gasket or a new bead of sealer and reinstall the cover plate. Then, you would remove the bolt or screw that is built into the cover plate, insert the fill wand or bottle tip and start filling the differential. Keep filling until the fluid starts to run out of the bolt or screw hole. Reinstall the bolt or screw, clean up any excess fluid and your done.

Check the specs in your hand book or workshop manual but normally 2 pints will cover it . make sure that you use the correct oil. If it is s limited slip differential you can ONLY use Limited slip oil but if it is a normal diff then you can use either oil The grade should be oep 8w-90

Changing rear end oil

Most rear differentials, it's a drain and refill operation.

SOME differentials have a drain plug, but others have ONLY a fill plug.

If yours doesn't have a drain plug, then you need to suck the old fluid out, with suction/transfer pump:

You can also use this to refill with the new fluid.

Most rear ends are filled to the bottom of the fill plug hole.
If you overfill, just let it overflow/drain until it stops dripping.

Now, different differentials require different fluids, so check what you need.
It might be in the owner's manual.

Adding fluid to the rear end

Hey, Welcome to FixYa!

If you have already purchased your 80-90W gear oil you will notice how the bottle is shaped. Long and has a nozzle at the end. Simply park your truck on flat level ground. Remove the Circle rubber inspection plug on the rear end cover. Then begin filling it with fluid. Continue to add fluid until Oil just starts to run out of the hole. Replace the plug and your all set.

If i helped you please don't forget to rate me. Cheers!

How many fluid drain plugs on hyundai elentra 1998? 1 for oil 1 for trany and 1 more

You should have a drain plug on the Oil Pan for oil, the tranny requires you to pull the pan to drain the fluid, on on the radiator in order to flush the radiator and one on the rear end in order to check the rear end gear oil level. That is all.

Humming noise in rear end. The car has sat idle for 8 years

Sound like your rear end needs gear oil. If you look at the backside of your rear end about halfway up there will be a bolt that should be 9/16 in size, you take that bolt off and you stick you finger in there to see if theres fluid. If you don't feel fluid then you will need to ad some. When you go to get your gear oil there is a pump like thing they have at the auto part store that will thread on to the gear oil contiainer and it has a hose on it, you stick the hose in the bolt hole and pump the fluid in until it starts to come back out. hopefully this fixes your problem and it definately sounds like thats your problem

Where can I find the inlet to poor gear box oil in to?

Depends on the make year and model, Engine size and transmission type and if it's 4wheel drive or not. Gear oil can possiblt go in the front rear end the rear rear end, The transfer case, The manual transmission. Some units don't use gear oil. Some manual steering gear boxes use gear oil too. Most all gears boxes don't have a way to pour the oil in as they have level plugs in the side at the normal fluid level. These plugs are located on the sides and they frequently can be turned with a 3/8 in drive ratchet extension. If the oil comes out or is just inside the hole with the vehical parked leavel then it's full. Yes they also have drain plugs and they frequently have the same kind and size of plug on the bottom as on the side.

What oil/fluid do you put in the rear axle of a 2002 8.25 with ABS from a Liberty Sport?

Hello dennispcarne: My name is Roger and I will help you. Your vehicle needs to have a 75-140 synthetic gear oil. If you have a track-lok rear end? You need to add a friction modifier to the differential also. This would be a posi-track rear end. This fluid and modifier can be purchased at most part stores. Should you need further help lease just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

Rear end whine on my 2002 ford f150 fx4 supercrew is it clutch pack?

Could be low on differential fluid, leaking from the wheel seal. The Differential gears could also be worn from low on fluid or ears was not lined up and have worn it self out.

Service the rear end, inspect the fluid's condition and measure the any play in the gears in the rear end replace is worn out.

You may buy some time by running 50% to 100% Lucas oil treatment in your rear differential. Good luck and hope your differential is not to badly worn.

There is a clanging noise when i put it in gear and can hear it while driving is it the rear end or universal joint

Check rear-end fluid level and play in rear pinion gear.
Check universal joints for play. If play is in pinion gear change rear end fluid and add a full bottle of LUCAS oil stabilizer, will quiet rear end noise.

Look on the back of the wheels by going under the vehicle. and tell me if you see a light oil. I am sure yours is a sealed pumkin. If not the oil in the pumkin may have leaked out
