Q: My car is very loud, what could it be

The presence of relatively loud noise, as well as vibration, could mean you have multiple issues. Typically, very loud operation is due to exhaust system faults but exhaust system faults will not generally cause vibration in the vehicle. To investigate the possibility of exhaust system faults as the cause of the loud noise, please request an exhaust system inspection.

Common causes of vibration in a vehicle include poor or rough engine operation, wheel bearing faults, wheel/tire assembly imbalance, and defective tires. Other, less common possibilities include suspension faults (strut/shock failure). Certain tire defects, particularly internal belt damage or separations, as well as irregular tire wear will cause vibration. Defective tires will vibrate no matter how "well" balanced they are and indeed some brand new tires with irregularities in sidewall stiffness and excessive radial force variation will vibrate no matter how well balanced. If you request a noise/vibration diagnostic, a certified mechanic from YourMechanic would evaluate all the possibilities, including tire balance, and resolve this for you.
