OKay. In Honda-Tech.com, most of the accord owners including myself with Eibach Prokit springs have been noticing a "clunk" noise, especially from their rear passenger side, whenever going over a speedbump or a deep dip. A member has gone deeply into researching, so he can diagnose the clunk noise, but still hasnt found the cause. More than 11 people are noticing this same problem at H-T and it is getting frustrating.

Is there anyone on this board who is experiencing this same problem or has experienced it in the past but is no longer experiencing it because it is fixed? We thought that the sway bar might be hitting the exhaust but that wasnt it. I know that the clunk noise isnt good for the car, but do you think its damaging our cars in any way?

Anyone who has any clue to this please help out. Thank you.

 

plastic corugated wire insulation, put it over the spring as far up as it will go. Problem solved

 

i had mine installed a few wks ago, and i also have this noise from rear right. Ive learned to ignore it..... radio up.

 

Can you please explain that in details? thank you.

 

I think he means you put it on the coils so when they come together they don't clank together.

 

oh you mean the rubber sleeves that cover the spring??

 

the upper 8 approx rear srings are all compacted together, so there would be no way to put sleeves around them??

 

is that exactly what i should ask for at home depot?

 

I've narrowed it down to like 3 possibilities to check... (oh and that was me who started the thread)

1) the tightly wound coils unwind over a bump as they lengthen and slam into each other because the springrate of those coils are really low, thus they compress/decompress too easily ( don't even see why eibach used those instead of linear rate springs).

solution could be to use the coil wrap like someone suggseted

2) the 2 strut bushings (inner and outer) might be too worn and compressed, thus there is play and it allows the strut or something to bang when the suspension moves.

solution would be to add washers or to try new bushings and washers to fill up the space

3) There might not be enough suspension travel for isntances where the spring lengthens (not compresses). I believe this occurs when the springs are installed on a low perch setting, thus you barely compress the spring a little to get the top strut mount on... meaning it only has that little bit of room when the springs lengthens over a pothole or something...

possible solution is to move the springs on a higher perch and thus give it more initial compression?? (might require a spring compressor).


--------
anyone agree/see some of these theories? any corrections? suggestions? other theories?

 

I have had pro-kits for about 2.5 years now, you learn to live with it or go slower over bumps. my ST swaybar hitting the exhuast makes more noise though.
