What is the Differential/Gear Oil all about?

Differential oil is a type of oil. Cars have a gearbox connecting the two axles. This gearbox is responsible for the conversion of engine power and its transmission to the wheels, allowing them to turn at varying speeds. This part of the car is called the differential, and lubrication is needed for it to function properly. Differential fluid, also called differential oil, provides the lubrication and cooling of the car’s differential. The fluid is there to protect the gears’ metal surfaces from friction, and to prevent overheating and burning.

Keep in mind:

  • Some vehicles have a front differential and others have a rear differential.
  • Some vehicles use a synthetic gear oil.

How it's done:

  • Check fluid level.
  • Inspect the rear housing for leaks.
  • Remove the cover (if the differential does not have a drain plug).
  • Install new gasket if needed.
  • Fill with new fluid.

Our recommendation:

Differential oil should be changed every 30,000 to 50,000 miles. You should aim to have the gear oil changed every 30,000 miles, but it’s a good idea to have a mechanic check the differential oil during regular maintenance services.

What common symptoms indicate you may need to replace the Differential/Gear Oil?

Gear oil is contaminated with metal particles or other substances.

How important is this service?

The differential is responsible for transferring the power from the engine to the transmission and the wheels, and for controlling how much power goes to each wheel. Like many aspects of your vehicle, the differential requires oil to act as lubrication. Differential oil allows the differential to move smoothly and consistently, which allows the vehicle to continue sending power to the wheels. If the differential oil is old, it may be contaminated with debris and metal shavings. This contamination will come into constant contact with the differential, which can cause severe long term damage to the differential.

Chevy Trailblazer - checking/changing front differential fluid

What kind of fluid goes in a Chevy transfer case?

Conventional transfer cases require SAE 80W or SAE 80W-90 GL-5 gear lubricant. Full time systems use SAE 10W-30 or 10W-40 engine oil. Conventional transfer cases require DEXRON®II transmission fluid.

Click to see full answer.

Also question is, is transmission fluid the same as transfer case fluid?

The transmission and front differential share the same fluid (ATF). The transfer case (uses Gear Oil) is a separate unit.

Similarly, can I use ATF in my transfer case? Servicing is limited to oil changes at the recommended intervals. The transfer case is always working, whether you use the four wheel drive on your vehicle or not. In the old days, transfer cases were filled with gear oil or automatic transmission fluid (ATF), but some modern transfer cases take specialty lubricants.

In this manner, what fluid goes in a 205 transfer case?

As has been discussed in previous posts, NP205 transfer cases require 80-90wt Gear oil.

How do you fill a transfer case with fluid?


  1. Secure the vehicle on a level surface.
  2. Locate the oil fill plug on the transfer case.
  3. Remove the top oil fill plug.
  4. Using a flashlight, check for oil at the fill plug hole.
  5. With the top oil fill plug still out, remove the bottom oil drain plug to drain the oil into an oil drain pan.

Whine Noise From Rear Axle (Diagnose and Replace Rear Propeller Shaft With New Tuned Torsional Damper Rear Propeller Shaft)

2004-2007 Buick Rainier
2002-2007 Chevrolet TrailBlazer
2002-2007 GMC Envoy

This bulletin is being revised to add model years and update the models affected. Please discard Corporate Bulletin Number 03-04-17-002 (Section 04 - Driveline/Axle).


Some customers may comment on a slight axle whine heard only on deceleration or coast conditions. The noise peaks at about 77 to 83 km/h (48 to 52 mph) before quieting at about 72 km/h (45 mph).


"Inherent" ring and pinion gear whine.

All gear driven units, such as automotive rear axles, produce some level of noise that cannot be eliminated with conventional adjustments and repairs. "Inherent" axle noise can be described as a slight noise heard only at a certain speed (typically between 72-96 km/h (45-60 mph). The presence of this noise is not indicative of a functional concern with the axle assembly. However, some customers may find that this "inherent" axle noise is unacceptable.


If the noise is not correctly diagnosed as "inherent" and having a peak in the narrow speed range of 77 to 83 km/h (48 to 52 mph) on deceleration or coast conditions, the addition of a tuned torsional damper propeller shaft can aggravate the perceptible noise level. It is extremely important to first diagnose the rear axle noise as "inherent" before installing a new tuned torsional damper propeller shaft. Refer to the applicable diagnostic information in the Rear Drive Axle subsection of Service Information.

The new service propeller shafts are only designed to correct the noise condition described above. They will not be effective if repair attempts are made to correct other noise conditions. If propeller shaft replacement is needed for any other reason, the existing service part number propeller shaft should be used.

Replace the rear propeller shaft with a new tuned torsional damper propeller shaft using the applicable part number listed below. The new propeller shaft incorporates a damper assembly to lessen noise transmitted from the rear axle assembly. The new propeller shaft should be used ONLY after diagnosis concludes that it is an "inherent" rear axle noise and no physical damage or incorrect adjustment exists. Refer to the Propeller Shaft subsection of Service Information (SI) for rear propeller shaft replacement procedures.
