Did you figure out yet what this noise was?

mikelexF

no they cant figure it out... I'm suspecting it might be the tire size being irregular and hitting the inner fender bolt causing noise. just trying to avoid bumps/potholes now.

this same annoying noise is happening to me after getting my BCR coilovers installed. its happening to my rears but a lot louder on my driver side. im not sure if im noticing it more and more or its getting louder. i took it back to the shop that did the install and they said they checked all of the bolts and everything was tight. they concluded that my pillow ball mounts were defective or worn. i did get them used on CL but seller told me they only had 3k miles on them.

i guess ill be contacting BC for new ones? frustrating...

I have the same knocking noise over big speed bump at medium to low speed. Been happening for 2 years now. I only have about 30k km and am completely stock. I mentioned it to my dealership, they replaced both rear shocks and the noise is still there. They have no idea what's causing the noise and am out of warranty now so I guess I will live with it.

A blown strut will make a knocking noise.

These cars don't have struts. No car with double wishbone suspension does.

Sorry, I meant a blown shock. I had the right front replaced under warranty due to failure which resulted in an annoying thumping noise.

Do you have after market sway bar end links? The spherical ones bind and make a thunk around corners and bumps... Mine just started doing it
