Yup ... and IF the mounts were squashed in on the the shock bushes due to the bolts being over tightened ... then that will cause the seals to chop out really quickly and can even cause the shaft to snap ... Beer can coolers made from wet suit material make good shock covers to help keep dirt out ... or you can buy covers from SGR USA ... The grub screw either holds the adjuster on or makes the inner shaft turn ? ... Just a guess ...
