2009 800 I broke my factory sprague, replaced it with new alluminum cage, rollers, pins, new fluid, all the air is bleed out, but seems to be somewhat stuck in 4×4, the indicated on my cluster goes out, but if I purposely spin my rear tires on ice, while the 4×4 switch is in 2×4, front tires will go in and out of enguagement. When switch is in 4×4 mode front tires are locked in as they should be. Any ideas, also a polaris tech did my work for me (after hours) and he doesnt really know whats causing it.
