I bought a set of F2 coilovers about four months ago, and up until now everything has been great. About two weeks ago my front driver side coilover started making clunking/loud tapping noises while driving. The noise is most obvious and easy to hear when making slow sharp turns, such as pulling out of a parking space. I have already checked for spring binding and the spring turns with the coilover perfectly fine. Also, I have checked the spring preload and have made sure that the top nut was tight. My front sway bar is not installed right now so the sound can't be from the endlinks either. I recorded an audio clip of the noise. In the clip, I have the front end of the car jacked up and I am just grabbing the front driver side wheel and turning it from lock to lock a couple times. Also, the sound seems to be coming from the top hat area, but I have sprayed lubricant onto the pillowball bearing and that doesn't seem to be helping. I am starting to think that the pillowball bearing is defective. I think I am going to have to take my coilovers apart and inspect the pillowball bearing, but I just want to know what you guys think first. Thanks.

Here is the audio clip... http://s90.photobucket.com/albums/k2...loverClunk.mp4

 

are you sure that it isnt a bad outer cv-joint on the shaft. thats what they do when they go bad.

 

I'm almost positive that the noise is coming from around the top hat of the coilover, so I don't think its the CV joint.

 

i was gonna say it has to be your axles but after hearing the noise i doubt its that.

 

super tighten the adjustment collars. i had same problem
