Ever since I’ve had my grizzly 07 700 bought in 2010 I’ve had very stiff rear suspension. I am currently in the process of replacing axles etc and was wondering how much movement the a arms should have. When I tighten them up there is little to no movement. Is this the culprit for the stiff rear suspension? I’m wondering does that inner tube through the a arm bushing supposed to bind with the rubber bushing or move freely?

Thanks
