What Causes Unbalanced Wheels? Wheels can easily become unbalanced if the car is driven over a rough road surface. The vibration from the road can cause the weights on your wheels to shift and become unbalanced. If you drive over a pothole or kerb, then the wheel can bend and become unbal...
What causes agrinding noise when turning the steering wheel? A car is made up of moving parts, and some of them are located in the steering andsuspension system. Any one of these components malfunctioning can result in a grinding noise as you turn the steering wheel. Faulty power steering r...
Measuring torsional vibration requires measuring the RPM of a shaft with a high number of pulses per revolution (PPR) (i.e. taking many samples per rotation as the shaft is rotating). To capture the torsional vibration, a high PPR must be used as the speed is changingwithineach single revo...
Steering Pulling: You might realise that you have to fight the steering wheel to prevent your car sliding left or right, while driving straight. If it drifts or swerves to a particular side, it is a clear sign that the wheel alignment is off. Uneven Tyre wear: This is one of the most...
a slight deviation in the shape of the wheel. At high speeds, a tiny imbalance in weight can easily become a large imbalance in centrifugal force, causing the wheel/tire assembly to spin with a kind of “galumphing” motion. This usually translates into a vibration in the car as well as...
steering wheel. Braking issues are also a symptom. For instance, if the vehicle nose dives when applying the brakes, then strut replacement might be necessary. An unusual vibration following driving over a bump is also a possible sign of strut problems. Signs of hydraulic fluid leaks under the...

Vibration and Shaking: When the shredded tire flaps against the road and undercarriage, you will feel the thudding or shaking through the steering wheel, the seat, and even the floorboards as the car becomes unstable. Heavy Steering: However smooth and responsive your steering usually is, it wi...
How to spot: Note TSB 13-053, which was for a vibration, judder, or light acceleration from idle. When the car is cold, put it in reverse and see if the rpm climbs. You can also get dirty and check the undercarriage for leaks from the gearbox seal. The easiest way to check for ...
