The differential is that item that allows one shaft to move separate to the other connected shaft. That is to say the left wheel to go faster /slower than the right wheel as in going around a corner or moving on uneven ground. There is one in front wheel drive vehicles , in rear wheel drive vehicles , and if you have an All wheel drive vehicle there is another between the front wheels and the rear wheels in the transfer case /gearbox. Unless you have metal or water contamination in the unit or have used the wrong oil in the unit it is not necessary to flush out the diff. Changing the oil as you would the sump oil is sufficient ( drain out and refill).A word of caution here. There is a special oil used in limited slip differentials so make sure that you replace the drained oil with the correct oil for the diff as damage will result if you don't.

Your car is a front engine, front wheel drive; the differential is part of the transmission. You should change the transmission fluid as per manufacturers suggestions if it is an automatic. It is different for different cars. If it's a manual transmission you should change that fluid as per manufacturers specs also. It's not very often.

The differential is the gear mechanism, that transfers rotation from the drive shaft, which itself comes out of the gear box (or transmission), out to the wheels. That model will be a front wheel drive, from memory, so at the front of the car. It is filled with OIL and this is a different oil to your engine oil (i.e. not interchangable) - It probably doesn't need to be flushed, but a regular change is appropriate, about every 30,000 to 50,000 miles. THis is a tricky but basic job, and best done with the car on a hoist. It is a simple drainplug/topup hole process, however if your diff is playing up, then it may need the covers taken off - mechanic is appropriate for that..

What is a differential on a 1997 Ford Escort


The differential is inside and part of the transaxle. A transaxle has both the transmission and the differential together as a single unit. On rear wheel drive cars, the differential would be in the rear end- the large center case on the rear axle. With front wheel drive, the differential is incorporated within the transaxle. It is used to keep the front drive wheels turning properly during steering turns.

The differential uses the same oil or fluid as in the transmission/transaxle case-it is all the same piece, not serviced or flushed separately from the transmission, or transaxle as front wheel drive cars are called.

Is doing a transmission flush the same as changing the differntial fluid?


No, a transmission flush replaces the fluid in your transmission. A diff. service would replace the fluid in the rear end also the transfer case and front diff. if you have a 4 wheel drive truck.

What recommended service is there for the 2005 equinox at 60,000 miles?


Definately do the plugs and wires, air filter, Transmission service, Brake fluid flush, coolant flush, power steering flush and differential (if applicable to your car) if money allows. Priority would be plugs and wires, air filter, trans service and coolant for now And then work your way down.

I was told I need to replace my front differential on my Lincoln Aviator. The seal was missing and all fluid came out and how pin is damage and it needs replacing and is costing me 900 dolars.


Hi,
Sorry to hear of the problem you have.
If all the fluid did indeed leak out, and the Lincoln has full time all wheel drive, and the vehicle was driven with the front differential dry , the sad news is the bearings will have been scored (ground up).
Depending upon how long the unit was run dry, will depend on the extent of the damage.
One could try and replace the leaking seal, flush the differential, refill with new fluid, and see how it runs. If the unit was not run to long dry, the above idea may work.
A trusted service Tech should be able to help with the decision.
A differential can be rebuilt.
Regards,
Wayne

I would do the coolant, but the others can go a lot longer.
The differential fluids should not be expensive, but the brakes can be expensive and not really warranted in my opinion.

Does changing your differential fluids help your transmission


HI, The transmission and differential assembly are two different devices that are linked by the drive shaft. Now; if your vehicle is front wheel drive only, you do not need to change your differential fluid because you wouldn't have one in that case. With that said; Changing the differential fluid will not affect your transmission. It will only provide better differential lubrication and functionality. Administering a flushing technique to both devices will only have an individual effect on both devices.

NOTE_ Differential maintenance is quite rare for the average city driver. Your transmission will require more attention than most differential assemblies. Now; if you do a lot of off-roading and pull heavy loads on the regular, i would have the differential assembly inspected every 16k. If not, simply, have the transmission checked every 10k for proper fluid and filter change.

I agree with the transmission fluid change.The differentials don't need anything unless they are leaking.You can do all this at home for less than 100 dollars including the other stuff they recommended.

Is differential & transfer case flush good idea at 95,600 miles?


You should have the trans., transfer, and diff. serviced, if you got an owners manual it will tell you in there at what intervals or the milage it should be done at,mostly around 35 to 50.000 you got that kind of milage on it and its never been done you better do it, the oils do break down and don't last forever, it could cost you more in the long run.

if this is a 5 speed manual transmission...all you need to do before putting your jeep into reverese is puting it into first gear and then shifting it to reverse to avoid any grinding or problems shifting into reverse...this isn't a problem just a poor jeep design by not installing an extra gear to eliminate this grinding or shifting problem
