Everyone’s favorite game, online forum driveline sound diagnosis.
I’ll use my best of my limited abilities to describe it and the situation that replicates the sound.
So it’s more of a click/tick than a thunk or clunk, its very light, almost dainty and quiet, I noticed it three weeks ago driving on a road trip in a city, I first mentioned it to the wife last night, she said she doesn’t hear a thing. At first I though it was something rattling around in the car but the more and more I drive it, it’s def drive line related. Sound is coming from the passengers side, 70% of the time it seems like it’s the front wheel area the rest sounds like it’s from the rear, amazing how sound moves around a car.
When and how it’s making the sound. So from a start or applying the brakes coming off the accelerator, so basically any shift in momentum cause the sound. It’s one and done, until momentum changes again, so one click coming off a stop then nothing until I coast or tap the brakes. The sound can reproduced turning left and right while changing in momentum. I also hear it letting off and coasting in a determined manor, you just don’t notice the sound as much due to road noise. Mainly it’s the in city driving that you notice it the most, slow rolling turning and braking or just stop and go traffic, gas/tick, coast/tick, gas/tick, brake/tick.
Now my guess as the cause.
The lightness of the click or tick that I’d describe it almost sounds like a brake pad with some minor play in the carrier. I haven’t changed the pads (I did change the rotors). Maybe when I reinstalled the rear pads the tolerance of the retainer clips/spring weren’t up to snuff and there’s some forward or back movement.
I’ve also read about the failure prone FCA bushing as being a weak link, but I don’t have any vibration or adverse feelings at highway speed (maybe this is an early phase of a failing bushing).
Other than that I’m thinking end links, but I don’t notice any increase or change in sound when the attitude of the car is pitched going across an incline.
Now’s the best part, what’s you guess?
