Rear shock makes noise...

[oynot400]

Well I was out riding the other day and I noticed that the rear shock was making a squeaking noise when I jumped. I don't know if it was the fact that it was cold out or the valve is starting to show wear? Either way I am having it rebuilt this winter. Has anyone else noticed this?
Thanks for any input. :)

Yep, check the linkage bearings.

Mine does it and i think it's the shaft seal squeeking. my slave cylinder does it on my truck when it's cold
