Interested in feedback on the 2011 & 2012 Troopers

Well, I know many 2008 & 2009 Trooper owners unknowingly became the R&D department for Joyner. I am curious to find out how the 2011 & 2012 Troopers are holding up? Have they resolved all of the common problems? What, if any, issues have you had?

My curiosity stems from wondering to recommed to my friend buying a used Trooper (cheaper but may have problems) or a new and "improved" model.

I haven't seen any comments anywhere on the new Troopers. Maybe none sold yet? If I were going new this would be of greater interest-

Casey at JMC says he will have them for sale soon. He has units currently at EPA for certification. Similar to Joyner w/Chery 1100cc and 5 sp manual trans. Available in 2wd and 4wd. Does not appear to have low range so that's a bummer. Took a ride a couple weeks ago in friends Polaris Ranger and was very impressed on severe mountain trails near Payson. It went places my Trooper would never go due to low range option. Still prefer my Joyner but this new Renli looks sweet!

Hey fellas im new here but have recently bought a 2012 trooper t2. Love the thing for sure! Only have 190 miles on it so far but it seams rock sollid really. Only chinsy thing about it are the skid plates! They are around a 16th in. Thick alluminium and for us rocky trail runners/climbers thats way to flimbsy. Almost had a rock penitrate my skid and hit my gas tank to its getting new skids built at the welders. Its an awsome rig though for sure. Not sure if the rear diff is upgraded for the 12 modle wouldnt know what to look for. Also i ordered some 29x9,50 r14 swampers for it and got lots more planned for performance wise;)

Thanks for the reply 12TrooperT2. We usually don't hear from Trooper owners until there is a problem. Good to hear you are happy with yours. Where did you buy you T2?

The stock skidplates are terrible. The screws protruding out of the bottom are even worse. I recomment a skidplate made out of UHMW.

The welder i took the skids to is building the rear diff plate out of 3/8 in. Aircraft alluminium and the mane plates out of 1/4 in. aircraft alluminium. That should do then slowly build more for the whole bottom side. You guys know if this little engine will push 29 in. tires and klimb still if its stock?

I struggled with the decision to swap out my wheels and put a set of 31" on there. Did it and haven't looked back......except to smile! The extra ground clearance is awesome, and like Charlie says, 1st gear usability improved. I was worried that I would loose some of the rock crawling abilities, but I have still been able to climb all the same hills after the swap as I did before. I actually use first gear now though.

Still it should be said that the low end torque lacks the ability to impress, on an 09' model at least, regardless of the tire size.

What tires did you put Mariner - truck or UTV? And are you still running 14" rims?

Finally got my skid plates back and going to go test em out on an elk hunt tgis weekend they only cost me $150. Also found one problem area for anyone who has a 2012 joyner to look at. Problem is that the bolts are not locktited in place and vibrate loose on the brake callipers. Allredy rattled two of my callipers untill they fell free but nothing a little BLUE LOCKTITE not red cant fix. Also if you have had this problem pay attention to the other brakes as there is a thin washer between the mounting surfaces of the calliper and the hub housing surface. Also has anyone put any interco black momba tires on their trooper? If so how ya like em?

That little thin washer can be a pain to deal with. On mine, I tack welded it in place, making it much easier to reinstall the calipers.

I went to a brembo dual caliper used on motorcycles on my front calipers. Improved the braking, but still not where I want it. I had to fab some mount brakets out of plate steel for these to work. How is the braking on the 2011/2012's? Same I would imagine...they stop you but don't really provide much feel or grab?

I run 30" dominator 540's from superatv. They have been bullet proof. I don't even worry about carrying a spare. I hit a rock in Moab and felt the tire pinch hard against the rim, the kind where you cringe and wait to hear the hiss. Upon inspection I had a small cut in the sidewall, but nothing into the threads. My friends with Maxxis Bighorns have had 4-5 holes each in their sidewalls since I have owned these. They are soft though, so if you run on the road alot I would not recommend them. When we run on the slick rock in Moab I hear other tires churp on steep inclines/declines where mine just bit & stick.

Hey fellas have had a couple more isues with my 2012 trooper one was a problem that evaded me for a week before i figured it out. I came down a steep grade and i mean STEEP to and the fuel pump started getting loud after i leveled out it would get quiet like it got gas now and again so luckaly we made it to camp with only a few spits and sputtrers. After getting back i noticed fuel pressure dropping off and finally syopped falling at 10 psi so i bought the pump and filter (pump out of mid 90s Ford truck & filter from a Chevy) only to find out the fule regulator set screw had came lose so watch the regulater. And the other problem is with the right front break. When aplying break it slaps like it is grabing and is lose but all looks to be good and tight anyone else have that prob? Other than that this machine is great!

T2 Trooper has 370 miles on it as of post.

Hi there 2Scoops! So far i have almost 1200 miles on my 12 mod year T2 and its had minor problems. Some of which i have covered. The break caliper that was slapping was due to a sticky mud plugged port which the calliper floats on. One other isue i have is the lower hiem joints on the front a arms are getting sloppy but easy fix got new ones strait from Joyner for good price think 60 dollars total. Had one shock blow a seal on the front too but this is all due to 1000 miles of rough roads so something has to give eventually i guess. Oh and the headlamp wireing was ziptied way too tight which caused a short and killed the original lamps but new set of led lamps work great. So far my setup has only changed with adding the led head lamps and 15 inch m12 diesel wheels with 29x10.50 super swamper sx bias tires. Have lots more planed tho. Hope this help with your wonders.

Yes it does. Those are very minor. Good to hear it is holding up. The guys on the Wildcat forum have all kinds of crazy problems big and small. I just bent a tie rod on my Wildcat that would have never happened on the Trooper. They used flimsy aluminum tie rods to save weight. The Trooper isn't light but it is stout.

Have you read any of the posts about how to fix the steep down hill problem, easiest is to add a surge tank. Or did they move the pump to inside the tank?

      I have a 2018 Massimo Buck 400 with 278 miles. 
      Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      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...

      Hello,
      Before I invest $10k+ into a brand new UTV for the farm, I want to get my feet wet with a fixer upper and learn the mechanical side of things. I acquired a 2022 Hisun Axis 500 (Lowes-specific model) from an auction for $500. It has only 200 hours and 120 miles on the engine. It looks like the previous owner used it for ranch work and didn't drive it on trails, deep water/mud, or anything too crazy.
      While it runs and moves, it has some problems. It struggles to accelerate up any incline in high and low range and sometimes stalls when I let off of the throttle or change gears. When I apply throttle in neutral, it sounds like it is struggling for fuel/air and pops. When I decelerate, there is a grinding sound coming from the clutch, which I've read to be related to the one way bearing and is semi-common. The last thing I've observed is sometimes the speedometer display sometimes will show a much higher value for a few seconds after barely touching the throttle. Based on the documentation, if a problem is detected from the sensors, the instrument panel display should have an error code rendered on the screen in place of the time, but this isn't happening. Here is a video showing some of these issues (engine is exposed with console removed):
      https://www.youtube.com/watch?v=FFAkO5TaGps
       
      Here is another video of the clutches in action:
       
      I've done some research, but information on this specific unit and sister units is limited. There does seem to be transmission and clutch issues reported. I still need to check into the head gaskets. I don't have the equipment to test compression right now, but I do plan on ordering what is needed soon. I do have an order in place for some cables to read the diagnostics from the computer. There is a shop two hours away from me that works on Hisun products, but I am hoping the problem can be identified and is something within my ability to handle. Below is what I've already investigated.  I am leaning towards the primary clutch needing replacement right now.
      After getting it home and unloaded, I did the following maintenance/checks to it prior to operating it further:
      Changed the engine/clutch oil (and filter) and gear oils using manufacture recommended viscosity Changed the air filter and checked for cracks in the air intake flow. Verified good suction. Cleaned the throttle body Changed the spark plug and verified the gap was within spec (0.6-0.7mm) Changed the coil and coil wire Changed the fuel lines, fuel injector, and verified the fuel pump was outputting the correct initial prime pressure for ignition and continuous pressure after ignition. Also completely emptied the fuel tank and made sure octane 91+ fuel is being used per manufacturer specs. Ran seafoam through system too. Cleaned the spark arrester and verified no cracks or gaps in the exhaust flow Changed out the O2 sensor Checked all wired connections to ensure they were secured and no breaks were visible Checked the belt for tightness and for any signs of wear and tear Verified 4WD and the differential lock function as expected - still hesitates and struggles uphill Verified the fan gears in the shifter are not corroded and working as expected ECU was reset after replacing sensors and fuel-related parts  
       
      Thanks!
