Default coilover noise

Hey guys, got my Buddy Club's installed but its making alot of noise, like any small bump it makes a chunk sound. I'm going to try tighting the collars more with a rubber mallet, but I think the sound is coming from the collars and also the pillow-ball mount. Any other areas to check? All the suspension bolts were tightened and double checked, so all the noise is directly from the coilovers

The Buddy Clubs didn't come with the LCA bolt welded on, so i had to use a bolt, but everything is tight no question about that, except the coilover collars are hand tight so i'm thinking when the spring compresses, it puts a load on the coilover collar and its hitting it hard or something.

more noise is coming from the rear, but there is some front noise as well.

Always make sure your collars are tight, really really tight.

After driving more, I really think much of the noise is coming from where the pillow-ball mount actually mounts to the chassis. Its tight but it sounds like there is a gap there and the sound is when the car is coming down ontop of the pillow-ball mount. I'm gonna have a closer look tomorrow and lower alittle more too.

I tightened the hell out of everything, all perches, added some spring preload and tightened the nut on top too, the coilovers are tight as hell but...the clunk sound is still there. driving out of the driveway, and just down the road its clunk, clunk, bam, clunk, clunk. All nuts on the car are tight....i don't get it.

I really believe its the pillow-ball mount hitting the chassis where it connects, but everything is tight so i'm out of ideas with these things.

They are Buddy Club Racing-Spec coilovers. which i'm sure handle great, but i haven't go the chance to findout cause i'm scared to drive it fast with all the clunking, frustrating

I may just go to Honda and order four new top hats and get rid of these ****ing pillow-ball mounts unless I can find a way to shut them up

Oh, well the pillowball is basically metal on metal. I've seen and experienced mounts where the spherical bearing is just as loose as can be and it had all sorts of play, that'll make noise. Are they new?

Yup, brand new. I'm going to call Honda today and price new top hats.

Its not so much metal on metal, its clunk, bang, clunk while driving down the road. I'm expecting some noise and i'm expecting a very firm ride, but this clunking makes my car sound like a cheap piece of crap, and its very annoying, so its gonna go.

Also, called Buddy Club USA and they said that putting some Blue RTV silicone on the top of the pillowball mount so its between the pillow-ball mount and the chassis of the car may help. That there is a small gap there so when it compresses, it hits the chassis with a clunk sound.

I'll give it a shot and use generously, but i'm really not impressed that this problem exists on coilovers that are $2000cdn. f you know there is a small gap, why not shave some material off the pillow-ball so it fits snug, or include a piece of rubber padding on the top of the pillow-ball mount.


instead of following buddy-clubs advice

Actually, i'm going to make a rubber piece about 3-4mm thick to go between the pillow-ball mount and the chassis. This way its metal on rubber and 3-4mm thick won't interfear with anything.

But silicone will eventually come off from vibrations, etc, so rubber is the way to go

then i'll oil or grease the pillow-ball to keep it quiet.
