Shifter boshings. Search on it.
this is a common item. I have replaced mine twice in a year.
But I like to use my shifter alot.
My mech just changed them a month ago, but I think they may have come apart or out, because my shifter is sloppy again. But he'll fix it for me no problemo.
It is Able to be done DIY, but I prefer to just let my mech do it. he has all the right tools and the lifts to boot.
