Noise Or Vibration In Turns

WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.

Vibration associated with the Constant Velocity (CV) joints in the halfshafts occur in the 3rd and 6th order (3 or 6 events for each rotation). The inner tripod joint with three pivot axis has three events in each rotation of the halfshaft. This will produce a 3rd order vibration of the wheel rotation speed. The outer CV joint with 6 pivot axis balls has six events in each rotation of the halfshaft. This will produce a 6th order vibration of the wheel rotation speed. A 6th order vibration will create a high pitch sound, like gear noise. Use a vibration analyzer to determine the frequency of the vibration before replacing components.

SYMPTOM POSSIBLE CAUSE REPAIR
Clicking noise while turning.
  • Lack of lube in CV joint boots.
  • Replace the halfshaft.
Clunk or snap noise while turning.
  • Loose wheel or hub nut.
  • Tighten wheel or hub nut. Replace damaged components.
Loud knocking noise centering on inner CV tripod joints.
  • Damaged Differential side/pinion gears.
  • Remove halfshaft and rotate side gears by hand. Replace necessary transmission components.

Noise may also be caused by another component of the vehicle coming in contact with the halfshaft, brake or wheel assemblies.
