- The differential gears are responsible for distributing power from the driveshaft to the wheels. When these gears become worn, they can produce a whining or grinding noise.
2. Bad wheel bearings:
- The wheel bearings allow the wheels to rotate smoothly. When they become worn, they can produce a humming or growling noise.
3. Low differential fluid:
- The differential fluid helps to lubricate the differential gears and bearings. When the fluid level is low, it can cause the gears and bearings to grind together, producing a whining or grinding noise.
4. Bad u-joints:
- The u-joints connect the driveshaft to the differential. When they become worn, they can produce a clunking or clicking noise.
5. Bent or damaged driveshaft:
- The driveshaft transmits power from the transmission to the differential. If the driveshaft is bent or damaged, it can produce a vibration or noise.
