# What are the components of a differential?

Here is how a differential looks like inside

• 1 flange. (attaches to drive shaft)
• 2 pinion gear.
• 3 side gears.
• 4 ring gear.
• 5 left axle shaft.
• 6 right axle shaft.
• 7 pinion (spider) gears.
• Accordingly, where differential gears are used?

Wheels receive power from the engine via a drive shaft. The wheels that receive power and make the vehicle move forward are called the drive wheels. The main function of the differential gear is to allow the drive wheels to turn at different rpms while both receiving power from the engine.

How do differential gears work?

Car wheels spin at different speeds, especially when turning. But the driven wheels are linked together so that a single engine and transmission can turn both wheels. If your car did not have a differential, the wheels would have to be locked together, forced to spin at the same speed.

What is gear ratio of differential?

Differential Gear Ratio determines the number of times the drive shaft (or pinion) will rotate for each turn of the wheels (or ring gear). So if you have a 3.73:1 gear ratio the drive shaft turns 3.73 times for every turn of the wheel.

## What is a multi link rear suspension?

A multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms, and one or more longitudinal arms. A wider definition considers any independent suspensions having three control links or more multi-link suspensions.

## What is a Macpherson strut suspension?

The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front suspension of modern vehicles and is named for American automotive engineer Earle S. MacPherson, who originally invented and developed the design.

## What is a wishbone suspension?

In automobiles, a double wishbone suspension is an independent suspension design using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle.

## What is the wishbone?

The wishbone is an oddly-shaped forked bone that’s the fusion of two clavicles called the furcula. It’s located right between the neck and breast of a bird.

## What is a wishbone bush?

Wishbone Bushes. Wishbone bushes are found at the pivot points or joints on your vehicle’s suspension system. Wishbone bushes are made these softer, pliable materials to help reduce road noise and absorb vibrations and shocks.

## How much does it cost to replace suspension bushes?

The average repair cost for suspension bushes replacement is \$250 to \$700, depending on which bushes need to be replaced and the type of car you drive. A mechanic will need to inspect your vehicle first to confirm this for you. As a rule of thumb, the more movement bushes experience, the more wear will occur.

## What does a suspension Bush do?

CARS.COM — Bushings are cushions made of rubber, polyurethane (often shortened to “poly” or “urethane”) or other materials. They’re mounted on car suspension and steering joints to absorb road bumps, control the amount of movement in the joints and reduce noise and vibration.

## Can you drive a car with a broken sway bar?

Depending on the vehicle you’re driving, you may have a front or a rear sway bar, or you may have both. If you suspect that a sway bar is broken, you can still drive the car, but you must use caution. The way this will affect your drive will depend on if the front or rear sway bar is broken.

## What are the symptoms of a bad control arm?

1. Steering wheel vibration. One of the first symptoms commonly associated with bad control arms is steering wheel vibrations. If the bushings or ball joints in the control arm become excessively worn it can cause wheel shimmy, which may cause vibrations that may be felt in the wheel.

## How much does it cost to replace the lower control arm?

The control arm should be repaired or replaced as soon as there’s any sign of damage, and control arm replacements costs are typically \$117 – \$306 for the majority of vehicles. The part itself will normally cost between \$42 – \$103, with labor time usually an hour or two.

## What are the symptoms of a bad tie rod?

Symptoms of bad tie rods include:

• A squeak noise when turning or hitting bumps.
• A loose feeling, like slack in the steering.
• Shaking in the steering wheel on bumps.
• ## Can you drive a car with a bad tie rod?

If you are still driving your car, you don’t have a broken tie rod. You may have severely worn tie rods if your front tires are wearing unevenly (can be caused by a poor alignment as well), aligning the front end doesn’t fix your tire wear problem, or your steering wheel wobbles while you drive.

## What are the symptoms of a bad ball joint?

Symptoms of a Bad or Failing Ball Joint (Front)

• Clunking noises coming from the front suspension. One of the most common symptoms of a problem with suspension ball joints is clunking noises coming from the vehicle’s front suspension.
• Excessive vibration from the front of the vehicle.
• Steering wandering to the left or right.
