Differential Repair

Differentials defined: A differential is the way manufacturers get your vehicle’s tires/wheels to rotate perpendicular to the rotation of the engine or driveshaft. The engine spins clockwise at an angle from front to back. Then it has to spin left to right to power the wheels down the road. This is where the differential steps in. The differential is designed to transfer the twisting power to the wheels by using a ring and pinion gear set up to transfer the power perpendicularly. There are also side gears or spider gears that allow the wheels to turn at different speeds when you’re turning corners. Differentials balance the speed of the outside (most active) wheels by decreasing (by equal amounts) the speed of the inside wheels. (At times, one wheel can even rotate backward; e.g., when making very tight turns.) (Are your eyes crossing yet? If not, you might be a mechanic!)

Symptoms of a Deficient Differential

(usually seen on vehicles with 150,000+ miles on them)

Banging or clunking while turning corners

Clunking sounds as your vehicle begins to move and/or when stepping on and off the gas pedal

Howl or whine when accelerating at any speed

Intermittent clunking

Rumbling or whirring when traveling faster than 20 mph

Rumbling while turning

Steady vibrations that increase the faster you go

Symptoms get worse when coasting

Whirring noise when decelerating at any speed

As you can see, the differentials in your vehicle play a vital role in the way your vehicle’s wheels behave. When differentials begin to deteriorate and malfunction, you’ll notice definite signs that all is not well with your wheels. When you do, don’t delay. The longer you wait for differential repair, the more costly it can be to get you back on the road.
