304CR more groaning on the left track

Hello, i have a 2002 304CR with 1700 hrs, the problem is when i have the cab in a 45 deg off from the center moving forward and making turn to the right, i get more groaning noise from the left track when doing a turn. The noise goes away when the cab is straight. It tracks straight when moving forward. Also, when do i need to replace the stick pin, i have some slop. thanks, xr
