Do a search. It's everywhere on here. You have to rephase the drive shaft.

 

I don't think that is the issue. The shaft is turning all of the time. If it was the issue it should vibrate all of the time. It only vibrates when the front kicks in.

 

I noticed on mine that I only get vibration when the front tires loose traction and the demand drive engages, other than that I have no other vibration in 4x4 even at 78mph, its really noticeable on ice.

I have same exact problem and I have already had shaft replaced I would like to know what it is ?

I only feel the vibration in 4wd. This is my take on it. It is a torsional vibration that comes from the drive shaft speeding up and slowing down not shaking side to side. In 2wd it's still there since the shaft is turning all the time but it's not transferring any torque. The drive shaft itself isn't very heavy or stiff so you don't feel it. In 4wd that vibration gets transferred through the front diff, axles and all the way out to the front tires.

 

G-ray, you are on to something here. Vibration and harmonics is a science all of its own. The old XP-900 & 4's didn't do it. They also didn't have a tubular chassis. No corners on the tubing to deflect and eliminate the harmonics.

 

put piece of rubber between the carrier bearing and frame, this helped mine a lot.

 

Can you post pics of the rubber mounting idea at the bearing

 

Well I figure if I subscribe to all the post I'll finally get an answer maybe. I agree with the original post here, it's turning all the time,(driveshaft) so noise/vibration how ever you want to identify it should be all the time. On mine if I engage the AWD switch I have a noise, turn it off noise is gone. Also intensifies moving steering wheel left and right swerving motion. Doesn't matter what the speed. And for the first 12 hours no noise just started all of a sudden. The dealer is telling me this is "normal". BS!

 

I have the same problem. This is not normal nor acceptable. It drives me crazy and i want it fixed. Anyone have a theory as to why it gets much worse when we turn the steering wheel?

 

Mine too.. bought it little over a month ago, got 16 hours on it and started to vibrate in 4x4.. more so when turn side to side. Already know its going to be an issue with dealer as he's saying its normal. I don't agree. soon as I get answers I will post. its driving me crazy. please, anyone have any answers to this, please let me/us know.. thanks

 

I am having the same issue.

From what I understand these driveshsfts are very thin and bend over time. I believe thats why the vibration may show up later. Those of you that had the phased and balanced, did you do new shafts? Im not a fan of the rubber. It may mask the problem but if there is something vibrating that shouldnt be it will eventually cause problems. I dont believe you feel it while its not under load like G-Ray said. With that being said this wheel turning, changing the vibes throws off my whole theory.

 

Unfortunately I think all xp1k4's will have this issue. I dont think this is a "built of friday" problem. Polaris should look into this and give us an explanation, however many wont have a driect effect from this untill after the 6 month warranty so I would think thay wont say or do anything. :-(

I think your right about it being blanket issue. I do believe it will all come out in the wash. Unfortunately, your right. untill the problem shows up and is consistently breaking down and polaris has no choice but face a class action court case or address the problem I really doubt they will do anyhing. Kinda like with the belts/helix issues. I paid for my helix. They made it right eventually for me but when I wanted it installed on my rzr there wasnt a problem with the stock helix they said.

 

Mine has been vibrating in 4x4 since day 1. Some say phasing works, some don't. It seems the ones that take there driveline to shops that rephrase and balance have better luck.

I think G ray has some logic. I notice some people taking video of there driveline spinning. They seem to be approx. 1/4" out-of-round. I decided to do the same, take a video of my driveline. Low and behold, mine is the same as the others approx. 1/4" out-of-round or should I say it has a wobble.
I took the video down to my dealer. I showed Derrick (the parts guy), he said to bring it down and show Rob (the owner) on Monday. So we will se what happens.

My thoughts, the driveline has a lot to do with the vibrating.

Everyone with 1000's should see if there driveline has a wobble. If so, take a video of it and show it to your dealer. Or send them to Polaris.

 

I will be doing this for sure. Video is good proof!

 

my 2013 900 XP has a vibration as well. right at fifty hours..

 

I have a 900 as well, just outta nowhere it started humming in 4x4 only, its driving me nuts. Is yours the same issue, I can feel it through the pedal.

 

I think its caused by the different gear ratios in the front and rear. If you have tires spinning at different speeds is has to cause binding and vibration as the traction conditions change for each tire.

 

I agree that the wobble is not good and should not be there. The only issue i have with that being the problem is that the shaft is always turning and yet you don't have any noise and or vibration until the front drive kicks in. I think it is in the front drive and there is no fix for it. I think Polaris will have to redesign the front drive. I wonder if the 2015's have the vibrations???

 

does this happen at high speeds or at any speed. will be picking mine up hopefully on tax free weekend in sept, but my riding will just be slow trail/mud riding down here. i rarely get above 20 in my ranger right now.

 

Well Mine only does it at 5 to 20 or 25mph After that I don't really notice it.

 

well crap

 

Maybe yours won't do it at all :} Not all of them have the issues Good luck

 

fingers crossed now.

 

We re-phase and balance the 2 shafts as one shaft and that gets rid of the vibration. Have a local shop do that for you. Do it and you will like the results. We actually re-tube both shafts with chromoly tubing on our Z1 builds. I still get a slight "noise" when I engage the front diff on a solid hard surface when I turn left or right which is the diff.

We are running the 1k at 105 mph on the street with NO vibration now.

 

My 570 does the same thing. Like mention in 4x4 it gets loud and annoying. This being my first sxs I was a bit scared of the noise but the more I drive it seam to be getting used to it. But does the vibration not hammer out the bearings faster?

 

Yes it does.
