It’s slop in the transmission. You can verify it by removing the belt then turn the input shaft (the driven clutch) by hand and you can tell there is a lot play in the rotation until it actually turns the output shaft.

I have a 2013 850 xp I'm getting towards the end of my second belt at just under 2k miles its done it since I got at 250 miles. New belt makes no difference. im pretty hard on mine have already broken axle carrier rear cv axle and a few other things but still runs strong and have had no drive issues from the infamous polaris clunk im convinced its the weights in the clutch ive been recently been told to really blow the clutches out and clean them up well wich should be common practice. Have also been told on 13 and up it may have something to do with the active decent controll

It's the game of the front gimbal I have a 2022 just buying it several days later it started with the same sound

listening from the right side it sounds like it's coming from inside the belt cover. May be the clutch clicking as it engages

Did you ever find the problem. Mine is doing the exact same thing just two rides after my first service done at a dealer. Maybe something with the rear diff fluid change???

My 2020 polaris sportsman high lifter 850 is making that same sound don't know what to do bout it...

It is from where the axle is connected to the differential . slightly loose fit. wiggle the shaft on the diff and you will see

Friend of mine had a similar sound. It was inner CV joint on right rear. But our sportsmans are old. No idea what a new machine would feel/sound like

What is the name of your speakers 🔊??? Your polariz awesome man

Have u tryed it with the brake on like power brake it and see if it does it idk man anything worth a try lol

I have a 800 Polaris 4x4 and the teflon bushings on the clutch were pivoting

I have a 2019 570 and it makes the noise when I’m going about 20-35 kmh any suggestion

Mine just started doing this put a 2 inch lift on it. Of course with the great instructions that came with it they did not have pictures. With my luck I put the lift backwards and caused the atv to be lifted more than supposed to be. Did some research and saw the lift was on backwards. Noise was comin from the left cv so I felt the boot on both left and right side left side was loose and the u joint had came out but the right was ok. 70 dollar mistake on my part 😢

Oct 2022: Our 2021 570 will clunk on IDLE after it warms up and NOT at higher rpms. It has to heat up after a few miles. Otherwise around the yard for small jobs it'll never surface. Also removed both clutches and still happens. Seems to come from upper left of engine, again ONLY WHEN HOT. No extreme vibrations that makes it un drivable.

Listen i have that problem on mine also, samething your saying, off Weight n.p., with weight from reverse to low gear and vise versa, alors that Cluck sound. Changed all my suspension bushing, rear wheel bearing,removed clutch, inspect it, put it Back samething, to find out that the 2 upper bolts of rear deff were loose and the bottom one close to the drive shaft was Also loose. Unfortunatly to tighten them needed to removed... Again my upper tables to reach th2 bolts, and removed tie rods and shocks to tight the one close to the deff. This fixed my cluck problem, meanwhile with time i Will see damaged the aluminum deff.housing.if so Will need to oversize bolts and housing. Will see with time. Hope this helps you out.

Your primary clutch has 3 weights that are held on by a pin on each weight. I had the same click noise and one of my pins had surface rust causing the pin to become bound up.the weight pins are loose after you fully tighten it. And the weight freely moves. As soon as a weight pin is bound up the weight that is stuck clicks because it is moving at a delayed rate of speed and slapping the clutch. Also you can tell if it's a clutch weight if your clutch engages the driven clutch at over 2000rpm . If your weights are free your driven clutch should engage at around 1800 or 1900rpm.

It could be the cv boot like you put a hole in it and when it doesn’t have grease in it it gets dry then it clicks

I got a 04 polaris and when i come off a curb or turning one way or another it will make a clunk noise. I dont know exactly where it is coming from but I for sure dont want a serious problem with it since its gonna be used for snow removal in the winter

No but most people say it’s slop in the rear diff. The u joint. I only use my quad in the winter so I haven’t really checked into it but i will soon. I do know that nothing is broke or will break. I only do plowing on this so if anything was messed up, it woulda been destroyed by now.

It’s and axle. Mine did the same thing. Nothing was broke in the axle just didn’t have grease.

My 850 Highlifter does the same thing which is why I did this search and found your video. I think it's the clutch engaging and disengagibg.

Clutch and rear differential yes. I got a 2022 570

My 2014 570 never did that. I don’t run mine in high water and I clean mine all up when there is a speck of dirt on it. I ride fast over dry trails, sand. I think there is something wrong with the diff.

Sounds like an exhaust damper. Is there one on this?

Rear diff bolt ?

I had this same problem with mine could not find the issue I kept looking and calling I rebuilt both clutches and still had the clunk until I looked at the rear drive shaft that hooks to the diff from the trans the splines on the shaft where worn and it would clunk like that I took it off replaced the driveshaft and greased it really good with new u joints and never heard that noise again

This is normal for all you that own a Polaris, and some other ATVs . I will tell you whv you here sloppy gearing in your "rear-end," Its is because of the gear "ratio". For the low end torque. This is needed when you climb hills, or rough terrain to prevent premature Wear and damage to the drive and transfer. The End result is that you end up with a higher tour gearing forgiving drive system then most. If the gearing was as tite as automobile we would be constily be breaking drive and transfer ends do to the high stress. Yes it can be annoying but this is normal at least for my three Polarises and Four of my other friends that bought them brand-new as well as myself , all different years. All sportsman. And yes' the anoing "clanking" from the slack in the drive. Hopefully this helps unless someone else has a better explanation.

It’s the rear axle, does it more when under load or sudden hard throttle like in low mode. I’m not sure why it does it tho.

I have the same problem on my 2022 850 try taking the rear shaft off and try it then and tell me if that works that'll tell you if it's a rear end or the clutches

My 2020 hd8 has a clunk when u put in gear an start to go it sounds like my 08 silverado when the rear end when out something s outta wack idk where to start lookin

Did you ever figure it out?

Did you happen to figure it out what the noise is my 850 is doing the same thing and it only has 65 hrs on it and it just started I baby mine as well

just run it. polaris are rattle traps but they keep going and going. ive got the 550 it cluncks and bangs..has since day 1. never got any worse and has been very reliable

See if you can make it make the sound by bouncing the rear end, looks like it may be suspension related.

It’s normal play in drive shaft and or it’s cuz your moving let off going again it’s free spooling and then catching up with itself totally normal for Polaris they do it right out of the crate

My clunks all to hell when you take your thumb off the throttle

Baught a highlighter 850 just now have 55hrs on it been to dealer 3 times they won’t fix until diff breaks kept saying it was driveline bolts or diff was loose or it was an axle it’s been making same noise from day 1 I’m guessing it’s ring and pinion lash or bearing tolerance after diff is warm from riding put in park and rock bike back and forth you will be able to hear and feel it in differential

This clunk for the most part is an engineering issue Polaris is well aware of it And does not seem to be affecting long term use

It's the clutch engaging and disengaging

I feel better after reading all the comments, my 07 Polaris hawkeye 300 4x4 I got recently does this and was worried I'd got ripped off. 😅

My brand new 2019 570 touring does that I have 2.5 hours on it and 13.6 miles it started about amd hour I'm to that 2.5 hour usage mark. I tap the throttle and it does it in all gears. Did you ever get it figured out?

It's differential backlash. Mine does exactly that too at the same hours. I'm an automotive technician and had to figure it for myself. ... If you remove the rear prop shaft (4 bolts ) and drive it in awd and the noise goes away, so it's not the clutch. that will confirm it. I did that to mine, no noise.

I bought a 2019 sportsman xp highlifter. The sales man was backing the bike off of one of those 1.5' high spinning show room platforms. I was standing behind the bike and heard a clank right when the clutch engaged and it started moving backwards. I wasn't sure so I didnt say anything. Now I have 50 miles and it clanks only once right when the clutches engage. Also sometime when I let off the throttle. I called the dealer and he said he thinks it's just the clutch springs engainging and disengaging. So I'm off shore right now and will be bringing it in in a couple weeks

It doesn't last when the wheels are up because all the weight is holding it down and the differential can't go anywhere

Rear diff bolts ovaled in the differential every single time the axle goes up you hear it smack

When you're plowing snow or using it to work, are you doing so in low range? If not, you need to. People assume belts take a while before they go bad, but you can foul up a belt in an hour if you're not using the machine properly. That clunking noise you're hearing towards the back is also where the clutches and belt drive is located. Notice the clunking noise occurs slightly after you go on the throttle and exactly when the drive line turns the wheels. This indicates a belt issue, possibly damage with the sheaves on the secondary pulley, but if I had to cast a bet, I'm betting it's a belt.

It the clutch.. all 4 stokes do it its the down shift on the weights

Sounds like the rear universal. Some one gave it a lil hell at the shop. Really hard to tell. Is there any play in the drive shaft at the joint?

Hey, good video! I was wondering what you found wrong with the clunking noise? I am having the same issue with only 100 miles on it. Thanks!

From what I've read, its actually normal for them to do that.

el mio es 2022 le pasa lo mismo es el cardan delantero tiene demasiado juego

I have a 2019 850 sportsman with 300 mi yr old clunks when i snap the throttle dont know why i greased all the fittings never abused drives me nuts im glad im not the only one with problem usually i am

It’s what they do 23 850 here and it clunks, will not effect long term use

Hold front brake as you accelrate

Run it until it breaks then you’ll know 👍🏻😁

Mine does the same thing man. I’ve hear just to leave it be.

Man sound like control arm bushing

It’s slopp in the front diff, Mina has always done this, I have 2 years left of warrenty so I’ll take it in if something happens

I bought a 2018 just 2 days ago. It had .1 mile on it. Not even a full mile. I unloaded it off the trailer and that was the first noise I heard. You know what it is???

Sounds like a. Drive line issue. A. Guys trying to sell one 700. Says its clunking

I've confirmed on my 2019 unit this is rear differential backlash noise and my Polaris won't do anything.... it's very noisy

Clutches in the rear end

Mine does it going to have it looked at before 6 month warranty up hopefully if it's not normal it gets fixed before it's out my pocket but regardless if it is normal I don't really like hearing it mines loud enough other people hear it and I got a 2021 atv and it's making noise that my 20 year old Honda don't

sounds like the cv axle

My 330 does it in forward motion drives me crazy

Jack it up and turn it off you start bouncing the rear axle up and down and you'll find the elongation area

Did you ever fix this? If what was it?...tia

Its the EBS helix rollers . Engin break !!..

My 2019 570 does it and I hate it. My buddy’s 2021 570 does not make it at all.

Transmission coupler

Man, I recently got a new 2022 sportsman 450, mine clunks out on the trail, sounds like drive line slop !

Looks to me that is a suspension issue.. I only hear it when the suspension torques or moves

Have a new 570 Sportsman with 6 hours on it and is making this fucking noise. I guess they're refusing to do anything about this? Do you have an update on yours?

Sounds like a rear u joint

Remove the rear shaft, put it in AWD and go forward... no noise I bet.

No matter how much the mechanics at Polaris wants to put the bs corporate spin on this is a serious issue with Polaris and they need a recall or buy people out on their purchases.

Same problem. I just try to ignore it. I don't like it.

Bought our bike yesterday have the same issue 10000 later I’m pissed

What’s this guys accent? Cool….

Probably your rear diff

Put. Weight. It clunks take away weight not as bad. Insepect drive shaft. Not chain drive is it

hey you fix the nois on your polaris sportmen what the nois

I’ve had my 1000 for almost 3 yrs always done the service on time myself and mine doesn’t clunk. You might want to go educate this punk with a 2x4.

U joint

lo areglaste

I feel I had this same problem. It was the axle. Troubleshooting video here. kzfaq.info/get/bejne/ir9hjLBzxpysdJc.html

drive shaft

Polaris is 🗑 🚮 🗑

Listen i have that problem on mine also, samething your saying, off Weight n.p., with weight from reverse to low gear and vise versa, alors that Cluck sound. Changed all my suspension bushing, rear wheel bearing,removed clutch, inspect it, put it Back samething, to find out that the 2 upper bolts of rear deff were loose and the bottom one close to the drive shaft was Also loose. Unfortunatly to tighten them needed to removed... Again my upper tables to reach th2 bolts, and removed tie rods and shocks to tight the one close to the deff. This fixed my cluck problem, meanwhile with time i Will see damaged the aluminum deff.housing.if so Will need to oversize bolts and housing. Will see with time. Hope this helps you out.
