Unless it is a coincidence than it must be the compression rod.
Did you refit the the compression rod ball joint seating cone?
If seating cone is properly insitu and not damaged, then I would bung a new compression rod on, or perhaps fit an oem compression rod bush to start with which I have in stock priced at £37.50.
However if it was mine I would stop pussying about and bite the bullet and just fit a new compression rod, cone and nut.
