How do you diagnose a bad differential?

5 Signs of a Failing Differential

1. Tire Damages. If you notice strange damages on the sidewall and outer tread of your vehicle’s tires, it may be caused by failing differential components.
2. Hard to Handle.
3. Vibrations.
4. Gears Grinding.
5. Whining Sounds.

What does a bad differential feel like?

Here are the most common bad differential symptoms to look out for: Your vehicle is quickly going through oil. Difficulty steering. A loud front differential noise, such as the grinding of gears, clunking, or a “howling” sound.

How do you know if your front differential bearing is bad?

Here are some of the most common symptoms of a failing differential:

1. Service Past Due. Like all components of your vehicle, your differential needs periodic service.
2. Leaking Differential Oil.
3. Strange Noises.
4. Vibrations.
5. Unusual Smells.

Why does my differential make noise?

If the cause of the noise is inside the differential, this can be due to either tight-meshing pinion gears, or too much backlash on these gears. Another cause could be worn out differential-case bearings, and these can also cause noise when turning.

Will thicker oil quiet a rear differential?

It is doubtful that your ring and pinion is making noise. It is far more likely that your pinion bearing(s) are the source of the noise. Running heavier gear lube will not solve anything.

Can a differential be rebuilt?

A complete rear differential replacement includes replacing the housing, gears, bearings, and seals. The average time it takes a certified mechanic to perform a differential rebuild at a shop is usually three to five hours. A rebuild on a commercial vehicle by someone without prior experience could take much longer.

What can cause excessive backlash in a differential?

The pinion gear is supported by two bearings, whose pre-loads are established by a crushable spacer between them. When a differential is set up this spacer is crushed by tightening the pinion nut; if the spacer is crushed too much, you get excessive backlash.

What happens with too much backlash?

Ring and pinion backlash. As the gears operate, they produce friction and heat. This makes the gears expand, reducing the clearance between the meshing teeth of the gears. However, too much ring and pinion backlash can cause gear noise (whirring, roaring, or clunking).

What causes differential failure?

The leading cause of a differential failing is due to using the wrong lubricant type and specialty lubricants. When water enters it will emulsify the differential lubricant and result in rusting on gear and bearing surfaces. Seized U-joints that result in vibration can cause differential failure as well.
