What is the problem when the differential is broken?
2 Answers
The reasons for a broken differential are as follows: 1. Improper operation of the differential lock by the driver, leading to differential damage. 2. The use of low-quality lubricants in the market resulting in poor lubrication, thereby causing differential damage. 3. Starting too quickly or wheel slippage can accelerate differential wear, leading to damage. The functions of the differential are as follows: 1. Transmit the engine torque from the universal transmission to the drive wheels through the main reducer, differential, and half-shafts, achieving speed reduction and torque increase. 2. Change the direction of torque transmission through the bevel gear pair of the main reducer. 3. Achieve the differential effect between the two wheels through the differential, ensuring that the inner and outer wheels turn at different speeds.
Yesterday my car made strange noises when turning, and later I found out it was a faulty differential. The differential allows wheels to rotate freely at different speeds during turns, which is normal, but once it fails, trouble arises: the car may jerk or feel unstable when turning, as if being dragged, especially on slippery roads. It can also cause uneven tire wear, leading to frequent and costly replacements, not to mention the danger. There are various causes, the most common being insufficient or dirty fluid due to lack of regular maintenance. Worn gears or damaged bearings inside the differential can also cause this, usually more common in older cars. If you notice unusual noises or discomfort when turning, get it checked immediately—delaying could lead to skidding or loss of control at high speeds. I once saw a friend’s car lose control on a curve and crash into a guardrail—thankfully no injuries, but the repair cost over ten thousand. In short, get it fixed promptly—don’t skimp on small costs. A professional shop can replace parts or fully refurbish it to restore safe driving.
