What are the symptoms of a failing rear differential?

Symptoms Of A Bad Rear Differential

  • Vibrations. A bad differential can cause vibrations that increase in intensity as you speed up and reduce as you slow down.
  • Grinding Gears. Grinding gears is another significant sign that your differential is failing and that the gears are wearing themselves out.
  • Whining Noises.

    How do you know which rear end you have?

    Stamped Number on the Axle

    To figure out exactly what axle you have, you can look for the Dana stamped bill of materials number. This stamped number can usually be found on the righthand side or on the longer axletube on the same side of the tube as the differential cover, facing the rear of the truck. via

    What does it mean for a rear end to go out?

    Typically, when the gears wear out — or the bearings fail — the differential will start to howl. You'll hear something that sounds like a deep whistling sound that goes up and down in pitch as you go faster and slower. via

    EPA-estimated mpg for the 3.6L V6 engine with 9-speed automatic transmission FWD. Shown with available All Wheel Drive feature. Safety or driver assistance features are no substitute for the driver's responsibility to operate the vehicle in a safe manner. via

    How much does it cost to fix a rear differential?

    The average replacement cost for a whole rear differential is between $1000 and $4000. Luckily, you can just repair it or replace it with a used differential, which will decrease the costs a lot. Most differential repairs will cost between $200 and $400 to repair. via

    Can you drive with a broken differential?

    You can still drive your vehicle with a bad rear differential, but it can cause severe damages. The problem may increase to the point of stopping you in the middle of nowhere. And, if you are asking about driving with a total broken differential, no, don't do it unless you want to damage the entire drivetrain system. via

    How do I identify my GM rear end?

    How do I identify a GM 12-bolt rear end?

    The easiest way to identify a 12-bolt rearend is obviously by the 12 bolts holding the rear cover onto the axle housing. The pinion shaft on passenger-car differentials is 1-5/8-inch in diameter and the cover is oval, measuring 10-15/16-inches wide by 10-5/8-inches tall. via

    What does a rear end sound like going out?

    Regular clunking every few feet can also be an indicator of a broken pinion gear and/or chipped and damaged ring gear. Overly worn out bearings tend to make a howling noise when they do not properly support the gears. Rumbling while turning, on the other hand, is a sign of bad wheel bearings. via

    Can a bad rear differential cause transmission problems?

    When the differential doesn't perform well, it creates metal-on-metal friction that wears down surfaces. The resulting heat weakens gears and can cause component failure and transmission problems. A bad differential makes the car harder to control turning corners, and that can be dangerous. via

    How long does it take to rebuild a rear differential?

    A complete rear differential replacement includes replacing the housing, gears, bearings, and seals.

    If new gears are needed the price can be at least $1,500. Going to the worst-case scenario, if the differential is beyond repair, you'll need the component to be replaced altogether. You can expect a rear differential replacement to cost up to $4,000. via

    Can you drive with a rear differential leak?

    Depending on the amount of oil seeping through the gasket, this may leave noticeable traces of oil on the undersides of the differential housing. A seeping differential will usually be okay to drive for a while, however, it will eventually progress into a full on leak as time goes on. via

    How do you diagnose a bad differential?

  • 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.
  • Rear differential noises.
  • Extensive and inexplicable wear and tear on your tires.
  • via

    How do you tell if you have a 7.5 or 8.5 rear end?

    The 8.5 rearend will have a round cover, and part of the cover will extend rearward to make room for the ring gear. You will also notice the large, flat, cast-in protrusions at the five and seven o'clock positions. These protrusions are larger than those on the 7.5 rearend. via

    What's better 10 bolt or 12-bolt rear end?

    First, the 10-bolt's pinion shaft diameter is 1.438 (25 splines) while the 12-bolt is 1.625 (30 splines) which makes the 12-bolt 13 percent larger in diameter and therefore stronger. via

    How do you tell if I have a 10 bolt or 12-bolt rear end?

    Just like a 10-bolt rearend, there should be stamped numbers on the axle tube – on the passenger's side. The numbers should let you know what gear-ratio came from the factory, the date of production, where the unit was assembled, and whether the carrier is Positraction or not (see charts). via

    How can I tell what gear ratio I have without pulling cover?

    With the transmission in neutral, rotate the rear driveshaft by hand. Count the number of driveshaft revolutions required for one revolution of the tire. If the driveshaft turns approximately 3-1/2 times, you have a 3.54 ratio, etc. via

    How do I know what gear ratio I have?

    Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio. via

    How do I know what axle ratio I have?

    What does a worn differential sound like?

    Regular “clunking” or loud “clicking” every few feet may indicate a broken ring or pinion gear tooth. “Clunking or clicking” when starting to move or getting on and off the gas might be loose yokes, bad u-joints or worn transfer case or transmission parts. via

    What causes clunking sound in rear end?

    Older rear-wheel-drive vehicles with a live rear axle and coil springs may have what's called a panhard rod that runs diagonally from the chassis to one side of the axle housing. The rod's bushings are a likely source of a clunking noise. Worn-out shocks or struts are also common culprits here. via

    What does a failing differential sound like?

    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. via
