Loud noise happening with Ranger

Recently, at low speeds my 2016 Ranger 900XP will eventually start to make a high pitched squeeling noise. The noise is quite loud when your driving and it makes you feel like something is breaking. If you accelerate faster it tends to go away. But I haven't been driving it because I fear this is causing more damage. I recorded the noise and uploaded it to YouTube.

I had my friend inspect the brakes and learned some pointers too. The noise while driving seems to be coming from the rear, but the rear brakes appeared fine. The front brakes both seem like they had (maybe minorly) scratched the rotors. I'm starting to think its something else, but will likely do a brake job on it soon.

Any suggestions on what to look for with this kind of noise? Or any tips on finding the source of the noise?

Best,
Tim

Belt squeal. Totally normal.


The belt rides low in the primary at low speeds. That means there is a bunch of aluminum pulley out there to "ring like a bell." When the machine accelerates and the belt moves from the bottom of the pulley up to a mid or higher position, the belt mutes any noise made by the pulley. It's the nature of a two pulley torque converter. They are noisy.



Have fun!

So I blew out the clutch area. It didn’t look dirty but it did send out some clouds. Then I greased all the zerks. So far the noise has disappeared. I didnt remove the belt, but it appeared to be ok. Maybe there was a bit of weight offsetting the spinning of the clutch?

Not sure how dust affects it but you should not see too much dust inside the cover. Most of what you blew out was likely rubber dust from the belt. Mine rides 50% on crushed granite and 50% street. I have not blown out my housing but mine will sing most of the time at lower RPMs. It's just the nature of the beast. My Ranger 2600 miles on it and the secondary is starting to make "CLICK-CLICK-CLICK" sounds occasionally as it binds and tightens up unevenly. Time to throw in a DuraClutch.
