Mule 4010 rattle


Recommended Posts

I have a brand new Kawasaki Mule 4010 4x4 trans.  While driving it has a vibration/rattle coming from the box area that I can't seem to locate.  I've gone over the vehicle and all the connections associated with converting the vehicle from single to two bench are securely latched.  The tail gate is firmly latched and I don't notice any lose bolts.  Looking for clues to what is vibrating causing the rattle and how to correct.

Welcome to the forum!

I've got an older mule 3010. That thing has always rattled since it was new. Mostly the trailer hitch, when the bar is installed. But I agree with Travis. If it bothers you then it's a dealer/warranty issue. When it needs to go back for the first scheduled warranty maintenance. I'd have them look at it then.

I've identified that the rattle is coming from the hinge for the tailgate.  It only makes the rattle/vibration at mid range RPMs.  If I jam a piece of flexible rubber mat into the jam of the tailgate it stops the vibration form occurring.  A permanent fix would be a rubber or plastic bushing inside the hinge to prevent it from happening.  I'll inquire with the dealer and see what they want to do for a fix.  Thanks for the responses.

Don't know if they'll work on that. Since it's just exactly like it was designed. However, if you give them some ideas that're easy. Like taking the pin out, and giving it a smack right in the middle with a hammer. Like how you fix a household door that creaks/swings by itself. Giving it just enough warp to hold it tight.

Not familiar with the new design, I have no idea if that's even reasonable. But it might work. Maybe grease the hinge pin?

If it's too much end play, maybe you could find a nylon washer at Lowe's? You wouldn't even need to pull the pin. You could just split the washer, and  push it in place in the gap at the end. Even if it wasn't end play, that might put enough pressure on the pin to quieten it down.

      Just received delivery of a 2024 AMP Pro.  Thought I'd start a thread with my impressions as I use it and learn more.  There doesn't seem to be a whole lot of real-world usage information out there on this model.  Hope this will help others as they research.
      Intended Use Cases
      Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property.  The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion.  Wasn't an original use case, but a nice added bonus.  Experiences So Far
      Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing.  The metal on metal contact has damaged the powder coating and the frame.  I expect a little better QC.
      I've only put a few hours on it, so not a ton to report on usage.  It isn't quiet; it's silent.  I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller.  The motor controller is Italian and made by Dana TM4.  Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent).  The motor is rated at 25 hp and 71.5 lb-ft of torque.  It feels very powerful.  All the torque is delivered instantly, if desired.
      The bed is huge and has an electric dump as standard.  Great feature but would like it to go up a bit more.  Probably not feasible from an engineering perspective, but I want and I need ;).
      Power steering is nice, but vague.  Probably common to many UTVs, but I am accustomed to more direct results from input.  Plan early and plan often.
      In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart.  I may get fatter, but I'll also get more done.  After a few days of usage, the battery meter has gone down by 1/10th. 
      Until next time...

      Our R&D team just finished the first unit and wanted to show you guys. Need more cargo space without losing the functionality of being able to fold down the seat to use the full bed? Eagle Mountain Outfitters, the maker of the original metal UTV roof, has designed a foldable rear cargo basket to meet your needs. Price is $625 + $30 shipping.  If you have any question's, please reach out to me at [email protected]

      so i just picked up a 2008 1100 trooper and iv ordered a few parts for it now and 99% of what i got fits perfect my issue now is my rear wheel hub is stripped out got a new cv and it fits great but i order 2 different hubs from 2 different places now and they are both wrong the spline opening is to small to fit the factory cv shaft and yes the shaft factory part #s are the same paid 250 for an original new replacement if anyone has anything that works to replace the original hub please point me in the right direction

      The conversion took about 350lbs. off the vehicle.  It never rode great, but now I feel every  crack in the road.  I have backed off spring compression nut to the point just under where they would move around if suspension was at full extension, but it is still very stiff.  I would like to put some softer coilover springs on it, but I have no idea what the spring rate is with the original springs so I would just be guessing on what to order.  Does anyone have the data for the original spring compression rate?  I am willing to give up a little ground clearance for a softer ride. Right now when sitting still the rear suspension is at or near full extension and the rear tires have several degrees of camber which will cause uneven wear if allowed to continue in this state.
