Pop pop pop no front wheel pull = disaster

I was hoping they had that problem fixed but I guess not- first I've seen with the 1k. Must just be the design of the Hilliard clutch.   

$20 K pile of junk!!!

I'm sure it had nothing to do with the dumbass driving it

one thing for sure I bet he was in major pucker mode. Ive rolled my rzr before because of the front diff not hooking up... When those front tires bite and are wanting to grab traction but the diff can't handle the load- I would say the machine failed him first and I think it caused him to back off but we will never know for sure...

If the power stayed consistent on the front and he kept it hammered, might have been a different outcome.. But I think we can still catogorize him as a dumbass based soley on the wheels and tires he was running .   

I think he said it was almost out of gas....Time for a new one!!!  

should have bought a can am

First of all, the front diff is pulling hard. The only problem I see is the shit ass tires on that machine. What is he doing, riding the road?????? Get the hell off the trails with those tires.

Focus on the front wheel and you will see it momentarily stop with every pop. It is a problem that has plagued me from day one- I recognize it very well. The rollers are slipping

I promise you.... different tires, better result!

I agree with you. Other than those tires just being wrong for the terrain, the combination of them with those wheels probably weigh a ton and contributing to the diff missing a lick here and there. You can't deny that the diff is unable to keep them constantly pulling. with every pop that wheel stops.

looked and sounded more like a CV joint popping to me

Yeah, that was a question I always struggled with mine when I started experiencing  the popping and losing pull at the front wheels.  Is it the diff or is it a CV joint? I came to believe that it was the diff and I guess I just got diff on the brain when seeing other rzrs behaving in the same manner..

It's just hard for me to imagine the axle,star, and balls slipping inside the cv cup without breaking or twisting up a boot- that is what would have to happen for the front diff to be pulling and the wheel stopping at each interval of that wretched sound. My axles and Cv's where always good and my boots never twisted-  but i guess sometimes things just ain't like they seem.

Are you guys seeing that front wheel stop?
If so, what do think the mechanics are behind causing that-- diff or CV? Got to be something in the drive line.

Jerrzr, I think you,re right it's probably the front diff rollers slipping. But if he had tires for that terrain there never would have been a problem with him being stuck to start with. We would never have seen this video and that 20 grand wasted.

atleast he looks happy

The front diff acting up in that vid was really the only thing that caught my attention and it  was very disheartening to see that.

Yeah those tires and wheels are shitty and his biggest problem with them I would say is the weight of them. But here is the thing about it--every time that front wheel stopped moving meant it was trying to grab traction but the diff just couldn't handle the load and pull it along and all it takes sometimes is just enough grab to nudge you along.

All agree on the crappy tire set up but that's really beside the point. Any tire can loose traction and when you find yourself in the same kind of situation as that guy with all for tires spinning and feel your machine wanting to grab but instead you hear that popping and feel your machine laying down on you Sucks Ass! You only have two options at that point. Keep open throttle or to let off...if you keep open throttle I can tell you what will happen- your diff will grenade (seen it happen several times).. If you let off, I guess the outcome depends on your situation and in this case the guy rolled.

But then again, that's just my take on things and you all know how I'm out in left field.. 

This is what I don't get. Why is it that only some buggies are having issues with the diffs? I can understand if everyone was having problems with the diff slipping under a heavy load. With yours I would guess that it could just be worn, but that 1K was brand new. Was it because he had a heavy tire/wheel combination and drove it like a dumbass? Given your left field status have you driven yours like a dumbass? What does the inside of the differential look like? Is it just a normal ring and pinion gear set with some type of clutch? Going back to my roots a little, but the Rhinos had the electric locking differential. I never had an issue with either one of mine. Couldn't steer worth a shit with it engaged though. Are the RZR diffs weaker? Or is it because of their different design?

This has nothin to do with the front diff but,I kinda liked the song that was playin on that video of the 1k crash. So much so that I googled it and found out a little more about it. Goes to show you the visual of watchin the RZR sure made the song more enjoyable. Here's the video of the group. I'll bet you'll agree.

10-4 on that one! Just like comparing the official "sail" video with jeb Corliss. Jebs vid much much better!


Google the official group vid and you will see..it Sucks!

lots of questions there and I have a lot that I can say about each one but I first would like to see some other opinions on the subject matters...But as far as me driving my rzr like a dumbass, I am sure  I have- probably on every ride.

I agree shitty tire combo, but yea I also see the front wheel stop with every pop of the diff. I've had mine pop like that goin up hells canyon, and u can feel it in the machine everytime it does it. It just won't pull and when ur in one of those spots u need all u can get. I ended up winching just because I didn't want front diff to blow right then. There's actually a video posted on here and u can here mine popping. Think it's under jellico or Tackett creek posted by big r.

Yep! Just found and watched it.  Its at 1:53 of  Big-R's  Jellico Thanksgiving 2013 video. I think you would agree that once you experience how that feels and sounds, it is unmistakable of what is going on.

All RZRs will do it when enough stress is placed on the diff and since the 4 seaters are a little heavier you will see it in them a little more often I think.

Also, I have noticed as the diff fluid becomes more and more contaminated with that extreme fine metal (which all of them generate)  the amount of stress it takes to cause the diff to slip becomes less and less. With real old and dirty fluid, the diff will pop and slip at the drop of a feather.  The best and about the only thing you can do--apart from riding your rzr like a dumbass   -- is to change that fluid OFTEN!

Yes his tires sucked for that hill climb and yes his front diff was poping and sliping for split seconds throught that climb. But if he would have better more aggresive tires that diff would have been poping and sliping more. From me going through two front diffs in my 900 I can say that one is on its way out. I am not for certian if it is the rollers inside sliping or the ring gear and pinion sliping. In my case the whole diff busted rite where the pinion gear and bearing is.

So glad I don't have to worry about that anymore...................

all the parts to an 800 diff.  with a super atv aluminum cage  its a simple diff that works great. the plastic cage is weak. but never know what will go once its changed
