The latter is of particular importance. Even if your ACE’s prop shaft is running as it should and everything is perfectly fine, always make sure to re-grease it periodically to extend its functional lifespan. To do this, find the grease fitting on the drive shaft towards the rear end between the universal. You access if from the rear side of the front right tire, and if you can’t find it at first, simply roll your rig a little in either direction until the grease fitting rotates around to the outermost side. So if your ACE is pulling to one side, rumbling like a diesel tug boat, or hitting up against the floorboards, a prop shaft from Everything Polaris Ranger could be the solution to your problems. Be it a new ball and trunnion universal joint, a propeller rod, or a full Polaris ACE drive shaft kit, at Everything Polaris Ranger, we’ve got the prop shafts and prop shaft components to keep you moving in the right direction.
