What would cause this damage?

[PranK]

Hi All,

I went to change my strut top and bearing today when I discovered there was a bit more damage than I expected to see.

What I'm wondering is, what would cause this? Maybe over tightening?



Thanks guys,

Christian

I don't know why they're upside down... They're perfectly upright on my machine.

Were they new when installed, or previously on other suspension?

Hi Dylan.
The spring cap is original i believe. The strut tops and bearings were replaced within 20k ago.

wonder if when the first nut was tightened down the spring hat didnt locate.
I had a similar issue with me mk3 cup kit.

Wonder if that then caused the dead bearing from not sitting flat?

It looked flat as I dismantled. But the damage is definitely on one side which would support what you said.

Could it not be over tightening?

im trying to remember how the stock suspension looks when going together, its been a while.
from memory that spring hat doesnt tighten down to anything? just slides over the shaft?

Here



The cap slides over the shaft, we don't use #7, then 6 (bearing) and 5 (strut top) are screwed onto the shaft, so if the nut (#4) is too tight, i'm wondering if the bearing would be the weakest link.

Thanks Dylan.
