Step 5: Add the recommended amount of gear oil to the differential, or until gear oil starts to dribble out of the fill hole.

Can you add fluid to a differential?

The refill bolt is usually on the passenger side, in front of the axle about halfway up on the differential casing. The small plug will unscrew and reveal the refill opening. Pour the correct differential fluid through this hole until it seeps back out.

What happens when a differential runs out of oil?

If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.

What happens if rear differential runs out of oil?

lack of oil in the differential will screw up the gears to a point where they'll be needed to be changed causing you the financial damage apart from having the other issues of a broken down car. In some cases it might even cause your car to be immovable (the rear axles won't turn).

What are the symptoms of low differential fluid?

If the gear oil runs low or becomes excessively dirty, it can cause the gears to whine or howl as they turn. The whining or howling is caused by lack of lubrication and may increase in volume as vehicle speed increases.

What kind of oil do I put in rear differential?

The construction and maintenance of front differentials mirror that of the rear on the same vehicle. Most differentials call for SAE 75w90 gear oil, however some heavy-duty and limited-slip differentials need SAE 75w140 gear oil. Consult your owner's manual for the proper weight oil to use.

What does a bad differential feel like?

One of the most obvious signs is a loud whirring noise that takes place when your vehicle is decelerating. You also may hear a howl or a whine when you are accelerating. This can be symptomatic of a bad differential.

How much does it cost to fix a differential?

Most differential repairs will cost between $200 and $400 to repair. Of course, this depends on the severity of the defect and what parts need to be replaced. For a rebuilt differential, you might need to spend between $400 and $1,000. On the other hand, replacing a differential costs $1,000 to $2,000 on average.

Is differential oil same as transmission fluid?

Transmission fluid and transmission oil are the same, but gear oil is for differentials, and in some people's minds, for transmissions, but you should not use just any gear oil in a manual transmission, as they may destroy synchronizers in their effort to protect extreme pressure.

What does differential fluid smell like?

Changing the differential oil

Sulfur compounds used in extreme pressure lubricants smell either like rotten eggs or worse depending on additive concentration. A good call is to wear clothes you can throw away and not get any gear oil anywhere you don't want to smell it for a while.

Can low gear oil symptoms?

Sudden up and down shifts, spikes in RPMs before shifting, strange grinding noises, and erratic shifts are also characteristics of this problem. All of these symptoms indicate you're low on transmission fluid and at risk of overheating.

How long will a differential last?

Q: How long do differentials last? The lifespan of a differential depends on various factors, such as driving habits, level of maintenance, the type of oil used during servicing, and many more. Under regular use and proper maintenance, differentials should last 150,000 miles or the life of a vehicle.

How often does the differential fluid need to be changed?

Generally speaking, differential fluid should be changed anywhere from every 30,000 miles to 60,000 miles. Your Chevrolet Owner's manual should outline differential fluid changes in the recommended maintenance schedule.

What does it sound like when your differential is going bad?

The most common sound of a failed differential is a whining noise. This is often due to poor lubrication within the differential, meaning there is a good chance that the differential fluid is leaking. If you spot a reddish fluid under the differential, there is certainly a leak.
