- The ticking noise you're hearing could be caused by several issues:
a. Wheel Bearing: A faulty wheel bearing can produce a ticking or clicking sound, especially when turning or driving at low speeds. Check for any looseness or play in the wheel bearing by jacking up the car and rotating the wheel by hand.
b. CV Joint: A worn-out CV (constant velocity) joint can also cause a ticking or clicking noise, particularly when turning or accelerating. Inspect the CV boots for tears or damage, which can indicate a failing CV joint.
c. Driveline Components: Other driveline components, such as U-joints or driveshaft issues, can cause a ticking noise. Check for any visible damage or excessive wear on these components.
- Groggy Engine Sound at Idle:
a. Vacuum Leak: A vacuum leak can cause a rough or groggy engine sound at idle. Check for any loose or disconnected vacuum lines or hoses in the engine bay.
b. Fuel Injector Issues: Faulty fuel injectors can lead to an irregular fuel flow, causing a rough idle and potential ticking noises.
c. Spark Plugs/Wires: Worn-out spark plugs or faulty spark plug wires can result in engine misfires, leading to a groggy or uneven idle.
d. Throttle Body: A dirty or malfunctioning throttle body can affect idle stability and cause the engine to sound rough.
It's always recommended to have the noises further diagnosed by a qualified mechanic, who can pinpoint the exact source of the ticking noise and groggy engine sound and provide the appropriate repairs.
