Noises from shock/suspension

[amsandun]

Hi experts,

My KSP130 has done over 100K now. After around 90K I started hearing a small sound ("tak/ටක්") coming from the front left tyre area (as I understood) especially noticed when taking a sharp slow turn followed by a bumper or a slope. About the same time, my service station supervisor also mentioned that front shock mounts are worn out and may need a replacement along with the front link rods as they were also going out according to them.

I didn't replace at that time but did replaced front shock mounts and links at last service near 100K. But the problem is still there but this time I hear the same sound at described events and also from the rear of the car. I hear it even when braking and starting to reverse some times. I think of taking the car to a reputed place and have it checked. Any ideas what's actually wrong and a good place you know that can solve this issue? 

Thanks.

It could actually be suspension bushings—not just the ones on the shock but also the links, control arm, etc...I would say just replace all the bushings (bushings themselves do not cost that much...its the labor most of the time that adds up). Also look at things like engine, transmission mounts and exhaust mounts.

yes I see, I just read some article after seeing your comment. What you said could be the issue with my car. I will have a check.👍

I forgot to update here what I did and found out with the above problem. I had this checked at a decent place in August and got it solved. The actual issue (sound) was coming from a loosen nut on a metal part below where the wiper blades are fixed and above the shock mounts.

I suspect that when I replaces shock mounts earlier, this area must have been removed and accidentally left this nut loose by the mechanic. All the nuts on this metal plate was properly tightened. 

This photo shows the place and exact nut that was the culprit. It was not easy to find this exact point as no one would think the problem is here at once. They checked all of front suspension system. During the suspension inspection, it was revealed that lower arm bushes were damaged and some issues in my brake calipers. That was also fixed but the sound was there after everything. 

Then only the technician suspected this place and had it removed. Once identified, it was a simple job of tightening the nut. 😉
