I’ve got a 2010 rzr i recently bought knowing the front diff needed bearings and seals. The vent hose was off and it was full of mud and water. I replaced bearings and seals and noticed the armature was worn. It didn’t stick to magnet well so I got it resurfaced and it seemed much better. The diff is getting power and magnet is working but still no 4wd. Hilliard clutch is fine. I’m not confident an $87 armature will fix my issue. Did the minor amount of material removed when resurfacing make tolerance too far off? Other ideas?
