A broken rear differential does affect driving. If the rear axle differential is damaged, it will impact the vehicle's four-wheel-drive functionality. Modern vehicle differentials are typically categorized into two main types based on their operational characteristics: gear-type differentials and limited-slip differentials. Gear-type Differential: Due to its structural design, this type of differential distributes equal torque to both wheels. This torque-balancing feature allows the vehicle to operate normally on good road surfaces. However, when driving on poor road conditions, it significantly hampers the vehicle's off-road capability. Limited-slip Differential: To enhance a vehicle's performance on rough terrain, some off-road vehicles and premium sedans are equipped with limited-slip differentials. The key feature of a limited-slip differential is that when one drive wheel loses traction on poor road surfaces, it can transfer most or even all of the torque to the wheel on a stable surface. This maximizes the traction of the functional drive wheel to generate sufficient driving force, enabling smooth vehicle starts or continued movement. The simplest method to achieve this is by installing a differential lock on a symmetrical bevel gear differential, converting it into a locked differential. When one drive wheel slips, the differential lock can be engaged to immobilize the differential, effectively disabling its torque-distribution function.

As a seasoned driver with many years of experience behind the wheel, I must say that a broken rear differential absolutely affects driving. The differential is a critical component that manages the speed variation of the rear wheels during turns, and when it fails, it causes all sorts of trouble. You can feel the abnormalities as soon as you start driving, such as severe body shaking during turns or hearing grinding metal noises, especially when the rear wheels may lock up during turns, making the steering wheel feel as heavy as if it's stuck. The vehicle becomes sluggish during acceleration, as if towing a trailer, and is prone to skidding and losing control on slippery roads. I personally experienced an issue on the highway that nearly caused a rear-end collision, so I recommend pulling over immediately to check if you notice these symptoms—don't push through it, as it could lead to driveshaft damage and double the repair costs. Leaving it unrepaired for a long time can also affect fuel efficiency and even shorten the chassis's lifespan. Get it fixed by a professional technician as soon as possible—safety first.

I just experienced this recently - driving my old car felt off, and a faulty rear differential was an absolute nightmare. As soon as I started the car, there was a clunking noise from the rear axle that got louder during turns, while the steering wheel felt loose and prone to losing control. Acceleration was sluggish, like driving with the brakes on, making the rear wheels feel like they were dragging. I avoided highways fearing accidents. After checking, I learned differential issues cause uneven wheel speeds, potentially locking the inner wheel during turns, leading to rapid tire wear and increased fuel consumption. Even daily commutes became nerve-wracking, forcing me to drive slowly or find alternative transport. Eventually, I took it to a repair shop where fixing it cost some money, but thankfully they caught the leaking oil seal in time for a quick fix. This reminded me to pay closer attention to my car's condition - address strange noises immediately to avoid costly major repairs later.

As an automotive enthusiast, I know a faulty rear differential can seriously impact driving. Simply put, it manages the speed difference between rear wheels under various road conditions, allowing the outer wheel to rotate faster than the inner one during turns to prevent skidding. When broken, you'll experience steering difficulties, inaccurate turning angles causing wheel hub friction sounds or body vibrations. During acceleration, uneven power distribution leads to tire wear and may trigger the ABS warning light. In severe cases, rear wheels may lock up during straight-line driving or cornering, rendering the vehicle immobile and requiring towing. From a mechanical perspective, common causes include oil deficiency or internal gear wear. Prompt inspection of fluid levels or component replacement is necessary to protect the drivetrain and extend vehicle lifespan. Neglecting this issue can result in repair costs far exceeding minor maintenance expenses while increasing safety risks.
