I had some new Tein (Advance z) coilovers installed on my car. Its been driving wonderful but when going over bumps, I hear this high toned/ metal on metal jingling noise which almost seems like a loose washer or loose coins bouncing around.
Does anyone have any clue what might be the cause of this?
Did the front strut assemblies come with upper mounts? I am guessing YES. Are those upper mounts lacking any rubber? I am guessing YES. Are those upper mounts metal spherical mounts that look something like THIS?
I am guessing YES…
Get used to the noise. It won’t go away, it will get worse. It is there because you removed the factory mount that used rubber to isolate road noise and replaced it with steel that doesn’t isolate road noise.
It may just be the angle of the pics but it looks like there is very little clearance between the components. They may be making contact when the suspension compresses.
Nah, there are plenty of instances where the OEM engineering/design is lackluster and can be improved via the aftermarket. The OEM shifter on my Mustang was crap. But an aftermarket three-post bracket/short shifter, and uprated transmission mount bushing provided significant improvement.
