I have an intermittent crunching sound coming from the front drivers side suspension. I have brought it in for a suspension inspection and the shop diagnosed it as a worn inner tie rod that is moving back and forth under acceleration and deceleration (the noise happens when depressing and releasing the accelerator). I have linked a video in which I recorded the sound, you can see it corresponds with the depression and release of the accelerator https://youtu.be/-pUehZrCKuk.
Initially the noise was heard only going up and down a very steep hill in the summer in stop and go traffic when releasing the accelerator, but is has gotten worse and happens on flat ground as well.
I was told I could re-create inner tie rod noise by turning the key to accessory power to unlock the steering and moving the steering wheel slightly side to side, but I was unable to re-create the noise by doing this.
The noise has been happening for quite some time now, and with the cold temperatures it has worsened in the loudness and occurrence. Below is a list of other possible culprits that have been inspected and ruled out.
- Engine /trans mounts: All in good condition, no tears, bolts tightened (https://youtu.be/G_3eNANqNVA)
- Struts: All in good condition, no leaks, tears
- Transmission: No hesitation in shifting gears, does not pop out of gear, no abnormal behavior
- Tie rod ends: both are almost brand new, no play, no abnormal sounds when turning
- Sway bar bushings: both present and intact, no tears
- Sway bar endlinks: no play
- Ball joints: inspected by shop, OK
In the mornings when it is colder and below zero the noise happens very frequently and is quite loud, it can be heard with the radio on. Once the car is warmed up the noise sometimes stops happening entirely or happens a lot less and is much more quieter, and hard to hear with the radio on. Or if it is warmer outside above 4-5 degrees the noise happens infrequently and is not loud even when the car is cold.
My question is would a torn inner tie rod noise reduce in occurrence and severity when the car is warm?
I would like to avoid paying for a repair that doesn't solve the issue. I am skeptical of this diagnosis as the shop that inspected the suspension also told me my brakes were worn to the caliper and needed replacement, but when I took of the wheels there was at least 30% left.
