How hard is it to replace a rear end?

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.

How long does it take to change a rear end?

There are side bearings and a pinion bearing which can pit or deteriorate, causing your rear differential noise. These bearings are part of a rear differential overhaul, taking three to five hours to complete.

How much does it cost to fix your rear end?

Depending on the make and model of your car, as well as its condition, expect to spend between $1,500 to $4,000. The other factor is if you buy a new rear-diff or a used/rebuilt one.

What causes a rear end to go out?

The most common cause of a bad differential is lack of oil, which could result in grinding at high speed, cause the carrier to break, or in most cases, block the rear wheels.

How much does differential service cost?

When changing the differential fluid, the overall differential fluid change cost averages between $80-$150 for the rear and $70 to $130 for the front change, coming in at a total price of between $150-$280 for the differential fluid change cost.

Can you drive with a bad rear differential?

Technically, you can drive with a bad differential, but it is not wise. The problem may get worse, to the point where it leaves you stranded somewhere. It can also cause damage to other surrounding components. It is smartest and safest not to drive with a bad differential.

Is it necessary to change rear differential fluid?

The differential is a series of gears that allows your inner and outer wheels to travel slightly different distances when you turn. Those gears require lubricant, and it's recommended you change your rear differential fluid every thirty thousand to sixty thousand miles.

Can a bad rear end cause transmission problems?

Believe it or not, transmission damage from a rear-end collision is not that uncommon. Some cars are more susceptible to rear-end transmission damage, such as those with rear or all-wheel drive because the car's transmission is actually a bit further back in the vehicle.

Can a bad rear end cause vibration?

When a rear differential fails, it can cause vibration, noise and fluid leaks that impact a vehicle's acceleration and driveability. A driver should consult a certified mechanic to deal with a bad rear differential and prevent further damage to the vehicle's driving systems.

What noise does a bad rear end make?

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.

How does a diff get damaged?

The easiest way to cause problems with your differential is allowing your car to spin out a lot. Every once in a while, unintentionally, spinning out shouldn't cause too much harm. It's these kinds of driving maneuvers that could crack or damage parts of your differential.

How do you know when to change your differential oil?

  • The oil is contaminated with substances or metal particles.
  • Grinding noise as you turn corners.
  • Humming noises because the gears are grinding against each other due to low lubricant.
  • Vibrations while you are driving down the road.
  • What happens if you don't change your rear differential fluid?

    If this fluid isn't changed in the manufacturer-prescribed intervals, then it can get dirty and thick, which could damage the differential over time.

    Does changing differential oil make a difference?

    Changing this oil is just as important as changing your engine's oil, and for the same reason. Metal-to-metal contact wears down surfaces and creates heat from friction, which inevitably weakens the gears and leads to failure.

    How can you tell if your differential is leaking?

  • You Smell Unusual Smells.
  • You Feel Vehicle Vibrations.
  • Weird Noises.
  • Vehicle Handling Difficulties.
  • A Leak That Is Coming From Your Axle.
  • You Have Damaged Tires.
  • You See Traces of Oil On The Underside of Your Car.
  • Puddles On The Ground.

    How do I know if my differential fluid is low?

  • Burning Smell from the Differential. When you notice a bad smell coming from your gearbox, you should take it as a sign of bad differential oil which can be contaminated hence not operating as it should be.
  • Weird Noises.
  • Vibrations.
  • Which is better limited slip or locking differential?

    Limited slip differentials provide your vehicle with the best traction around. Locking differentials might give you good traction too, but the traction that you will experience with limited slip differentials is better. For starters, they will make it easier to turn on roads which are slippery and wet.

    Do you really need locking differential?

    You will only need to engage your locking differential when you need extra traction, so you may only use it for a few moments on each off road adventure. There are two types of locking differentials – automatic and manual. Automatic diff locks will engage automatically when traction is lost.

    Is a limited slip differential worth it?

    Limited slip differentials are very popular on high-power sports cars, because as a sports car takes a corner at high speeds, the limited slip differential slows the car down considerably. A limited slip differential also generates a higher level of traction, which increases the performance and speed of the car.

    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 get differential fluid change?
