Help with trim and tilt noise

[Sinn]

My 2006 Yamaha F115 trim and tilt assembly was changed in August 2014 and I noticed the other day as I was trimming it up and down just to make sure everything was working properly before my next trip and as I was trimming up from all the way lowered it started making an awful noise as like something was crunching or like grinding, anyone else have or had this problem? I hope it isn't going out again. It was changed last time over warranty and they told me it was a $1,500 job. Hope it's something I can fix on my own
