front axle failure
« on: July 26, 2015, 06:01:52 pm »
Hey   ...   I just bought a new 2015 ZForce  800 53''  back in May  and  have not  had much  issue  till  this  last  few  weeks  .I just got it back from the shop  last week   from getting a busted axle on the passengers side replaced .    Now the  drivers side one  has failed   in the same way  (both  were inner race  failures  ) in the outer joint, i don't  even have 700 km on it  yet . The shop will replace them for  so long  under warranty  but  time will  run  out   is anyone else having this issue ?  I'm not  using  it really ruff  just seems every time i get in a spot  where i need the traction of  Diff lock   they snap like a twig   :-\

I have a 800 53" too and only about 250 miles on it. No issues yet but I'll be watching for this one.

I don't have the 53, but I can say can say the times I've used diff lock it's worked great. It was on stock wheels and tires though.

Since I've upgraded to mud tires and lighter weight rims I'm sure I'll end up breaking axles lif I use it much. Luckily I haven't needed it.

That being said, I was riding arguably the worst mud trails ever a few weeks ago and had a tire blow out. I rode on that flat for 2 hours with 4x4 on the entire time. I pushed the Z8 hard that night and nothing broke.

I know EPS can make it easy to break axles since you don't really gauge the bind you have your wheels in at times, in that sense it can be detrimental to you. Perhaps that could be it? I hope it's just a little bad luck you're going through.

Should we really be going through these front axle failures like this on almost brand new machines? Really?  ::)

My research shows front diff and axle issues are rare and are usually caused by operator error such as jumping in 4wd and applying full power when CV joints are hyperflexed as in fully turned or over lifted. This is true with most any brand though, not just CFMoto. There are however a few reports of some quality-control issues that lead to failures but considering the numbers, overall CFMoto has a pretty good track record so far. It is also rumored that Rhino(which are also made in China) makes their axles. If that's true, then they have to be a decent axle.

I would have to agree with NMKawirider. If you have the axle stressed and stomp on it, you will break something regardless of what you are riding. If there are too many reports of failure, than they really should look at axle material or thickness. Does anyone know of any other axles that can be used?

Interestingly, Big P ATV sales has Rhino axles for the U and Z force. Although they are in Thailand, it does show Rhinos are available for these. That should mean that SuperATV can get them as well as they are a Rhino retailer. They already carry the windshields for the Z8s.

maybe we can start to get a list together as to what oem prt#s they will replace and even if they are an upgrade or not. would be nice to know that we have options.

Just remember when you upgrade your axles and CV joints, the next weakest link will most likely fail.  Be prepared to replace a differential.  Upgrade the diff, and you will be replacing a broken drive shaft.

bezerk has a point. My thought on this is the drive line should be able to take some abuse within reason. I have had many machines over the years and haven't had a broken axle yet. Smoked a belt or two but I'm OK with that.  The new machines are putting out a lot more HP than before and some of the axles they are putting in there are just not strong enough to be pushed like that. Can-Am had plenty of issues with there axles when they rolled out the 650 and larger. Better now I hear with thicker shafts.

Just broke a rear on my 15' z8 ex.
400 miles on the machine and honestly it's been beat.
The break happened when jumping a table top obstacle on A course at an atv event that no one else had the balls to jump and were just rolling over it. Lol I was wide open.
Finished both rounds in "3wd"
Called dealer and he had one in stock, but said they just revised them and ordered me one. Had it in 3 days no questions asked

I have 3 friends near me  one with  a 600 snyper and the other two have  the 800ex and they use them fairly rough  and lifted  with bigger tires and  have not  busted an axle .  Both of  mine broke under what i would consider light strain  with no lift stock tires driving in a straight  line at low speed .The first was at the edge of a muddy  hole  where there was a 8''lip to get up on  dry ground the  hole it self was not deep  because most of the water dried up making the mud extra thick so i put diff lock on  in low range so i wouldn't get coated in crap   and soon as  the wheel came to the lip   the axle snapped   it never even broke traction   ... the second  one  was backing  out of a soft spot  that  got  deeper then i wanted to venture in to  and it snapped once out  of the mud on  the wet grassy part off the trail . I'm hoping it was just a bad batch of steal or  something

zforcejeeper, next time your out with your buds, can you get some info on how they did there lifts? Not much info out there on it. With the bigger tires did they have to change up some of the clutching?
