Partzilla Live Q&A Highlights – Polaris ATV and UTV Repair Questions & Answers

Polaris ATV CV Joint

What is a good sign of a CV joint on a Polaris Sportsman going bad?

John Talley: A good sign? Well it’ll actually be a bad sign, but what typically signifies one is going bad is that you’re going to hear a clicking, especially when you’re turning it, if it’s upfront. When it gets that extra bind when you’re actually trying to make a turn, that’s typically when you’ll hear it make a “click click click” sound. Another thing, just look at the boots, because what typically takes them out is the boot gets ripped; you can’t really see it until you start pulling back that accordion. But what happens is that it gets ripped, then water and mud get in there and they start to wear out the bearings and the surface areas much quicker than they should, and then you’re going to end up having to rebuild it or replace it.

Polaris ATV Drive

I have a 2004 Sportsman that has an intermittent squeal in the front end when I apply gas, even with hubs disengaged and before wheels rotate. Any ideas?

John Talley: Really? That’s interesting, because when I first started reading through there, I was thinking a bearing, because typically when wheel bearings go bad, they actually start squealing. And it’s a very distinct metal grinding sound that you don’t easily forget. But you’re saying that it’s before the wheels rotate, and you’re sure it’s coming from the front end? Because that would imply that nothing is moving, and yet you’re hearing the squealing sound, so that makes me wonder if it’s the belt starting to squeak. Maybe the sheaves are starting to get a little bit glazed, and they’re starting to squeak when they’re trying to engage on the belt. So I’d probably look there first and just listen a little bit more carefully to see if that’s where the sound is coming from. 

Polaris UTV Joint

What can I do to get the pin out of the U-joint on a Polaris Ranger? It’s stuck.

John Talley: I know what you’re talking about. All these U-joints are basically made the same way, and if you’ve been watching us transmit from this particular studio, there has been a Yamaha YXZ1000R behind us. … Getting those U-joints pulled apart was not a lot of fun, and they actually make a tool, I think K&L makes it, where it mounts on either side of the yoke itself and it pushes the pin through. Now you might be able to get it knocked out with a hammer, but if you’re dealing with it on the machine, you’re not going to have a lot of room to strike it with, so you may want to look into one of those tools.  … Once again, it’s just going to take raw pressure to push that through.
