Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driveline System: Tires
Most vibration in the rear end is caused by tires or driveline angle or imbalance.
Vibration is a concern with modern, high-mileage tires if they are not "true" both radially and laterally. They are more susceptible to vibration around the limits of radial and lateral runout of the tire and wheel assembly. On a vibration concern, follow the diagnostic procedure in NOISE, VIBRATION & HARSHNESS . They also require more accurate balancing. Wheel and tire runout checks, truing and balancing are normally done before axle inspection.
