Thread: KYB mounts/bellows are junk?

I have read and heard KYB mounts are junk and I think that mine are going bad. I was also thinking the design of the bellows might be junk because they integrate the bump stop into the bellows. I think this is creating an issue because the top of the bellows is metal. I would think it would be better to use a bump stop like what Monroe sells, because seems like the strut shaft is better protected.

The only reason I started thinking about this was because of this image on ZZPs site. I might take mine apart and use some new mounts and this style of bellows and bump stop:

Instead of this:

the top are OEM style, no?

can you find a picture or take one of what the KYB setup does and looks like?

Yeah OEM struts are setup like the above pic. Those are actually KYB Excel G/GR2's in that picture that ZZP put together.

That bottom pic is a picture of the bellows on my struts but I will have to try and find a better angle.

EDIT-

These are the only pictures I could find so far:

The top of this is metal and the bump stop is underneath that top metal plate:

Why is the bellow/bump stop design having anything to do with the mount? This is where you're losing me.

My bump stops just float there. That's what they do.

I am thinking that the metal on the top of the bellows/bump stop is making contact with the underside of the mounts. With the other style of bump stop and mount, it is a pillow style mount that even when making contact with the bottom of the mount wouldn't make a noise.

Plus I think the bellows just hanging there like in the KYB setup is a poor design. Unless you zip tie the bottom its open just open like a dress. The Monroe style bellows are at least lower on the strut.

I am not by any means a pro in suspension but just thinking out loud.

We will see shortly if I am correct or not. I have to check and see if my EVAP canister is making the noise because it is loose or the strut is making the noise.

I recently just opened up a set of kyb quick struts that I installed in June 2010. Both front mounts were torn and I could push the rubber out after I took the mount off.
All my dust boots were ripped.


Seems like only thing good was the spring and strut.

So I bought new monroe mounts and dust boots. Used the zip tie at the bottom.

But your right. The bump stop/dust boot just floats up top. Weird huh
