Several 19's are reporting this, here's a thread, hope it help and let us know.
Four adjusters; two on top facing up (pushing up), two in front facing forwards (pushing forward), that's two per side. 2014-2018 model years, should be same for 2019.2 front stops adjusted, then put back to where they were originally at as I didn’t notice a difference. Is there more than the 2 front stops that are adjustable? I did not pay attention to that. I didn’t see any rubber mount over the engine cover but didn’t look that hard either.
