FRONT AND REAR DIFFERENTIAL
Location of your differential is dependent upon which wheels of your vehicle receive power from the engine. For instance, a rear-wheel drive vehicle uses the engine to power the rear wheels which means that your differential would be located and mounted on the rear axle. On the opposite, a front-wheel drive vehicle will likely have a transaxle that would function as both the transmission and the differential. In the case of 4-wheel drive and all-wheel drive vehicles, they would be equipped with both a front and rear differential.
The inside of your differential are several gears and bearings. They are all interlaced and rely on each individual part to keep the differential transferring power. To keep it running smoothly, the differential requires a lubricant called differential fluid that flows amongst the gears and bearings.
DIFFERENTIAL PROBLEMS AND SYMPTOMS:
As all vehicle systems, the differentials require maintenance as well. If a bearing becomes loose, or thin differential fluid is causing metal to grind against other metal you can expect premature wear. You may experience some of the following symptoms when issues arise:
• Rumble sound when care is traveling more than 15mph
• Persistent clunking noise
• A whirring noise while decreasing your speed
• High pitch howling during acceleration
• Banging or skipping when cornering
