Installing new shocks in my "72" (KYB) and am wondering what this is that came out of the top spring perch? See picture.

Was this just caked in dirt or remants of something else?

Thanks!

Need more of a descriptive finding. Does it crumble in your hand like sand or is it old dry rubber?

Might be the "spacer". Part #13. I actually bought a pair for my car from Courtesy Nissan long ago. Not sure if you can find them now. It's just a hard rubber ring.

And still available from Nissan. https://www.nissanpartsdeal.com/parts/nissan-insulator-strut~54320-e4100.html?vin=&make=Nissan&model=Frontier&year=2024&submodel=&extra1=&extra2=&filter=(r=1686)

@Yarb I just cound't tell if was sand or rubber like.....maybe more sand.

This came from under the top spring perch not above like the spacer and insulator.

I was thinking more along the lines of a bump stop?

Was there Bump stops?

Thanks for the input.

Part 13 is below the insulator. It is small. Part 46 from SteveJ is a large part, apparently for a Nissan Pathfinder. Not sure if he's recommending an alternative. ???

There are aftermarket bump stops. But they are placed aorund the sliding strut shaft.

Actually the picture and part number is from the front suspension parts microfiche that is on carpartsmanual.com. If it says Pathfinder, it's because they used the same part on it.

The front struts have a bearing under the isolator. Part #53 in your picture. I assumed that this was about the rears because no bearing was shown or mentioned.

Anyway, some good leads to follow.

Yes, which strut is that? Front or rear?

In the front is a bearing about 40mm OD in the rear is a hard rubber disc with the same dimensions

The picture in my first post is the spring side of part #6 in Zed's post.

@Patcon This is the rear strut, The front looks the same.

The bearing at front and the spacer at back are there and in good shape. The insulators are also in good shape.

But if there were bump stops, mine have perished and are missing in action😍

So my question is were there bump stops? Assuming there were what are the recomendations for replacements?
