Unlock your Rhino's Rear End.

Well I want to unlock my rear end because I use it alot on asphalt and my yard. Plus it's like turning a bus!


Warn makes this little device for the wolverine to make it able to be 2wd. Seems like if you could have a custom axle made with this in the center and a longer cable it would be the ticket.

Install for it is here Warn 424 Unlocker

Or you could just leave it the way it is and get a good winch, LOL.

Your humor is lost on me???

Kinda what i was thinking? What does a winch have to do with it?
This thread is horrible. I would not want a rear diff. It would make it less safe off- road. Why would Yamaha increase the cost/price by putting in a rear diff?
Seriously?! It wouldn't make it less safe off road. Depending on the application "safety wouldn't change a bit". But with a diff that's capable of being opened you could increase mobility of the vehicle by 100s of percent.

You would cut the turning radius by multiple feet. Adding a disc on each wheel would make sense. With multiple discs you could control them individually and tighten the turning radius to virtually zero. Open diffs reduce axle and tire wear significantly.

An open/limited/lockable diff is worth it's weight in gold. A perm locked dif is almost as unfortunate as a perm. unlocked diff.

Completely agree. Especially for rock crawling. They turn like pigs with the rear end locked.

I want 2WD/4WD selector then a separate locker switch for front/rear.

Been telling manufacturer that for a while.

Funny thing on the RZR is they have a selectable rear locker for RZRs in Europe. Not in the states though.

And the Ranger is cool, but you can't have AWD and an unlocked rear. Only 2WD unlocked.
The Range isn't what it appears.

I haven't screwed with a Ranger much, but being given the option of locking or unlocking any of the diffs.. I guarantee that with a little determination, you can force any option desired onto the system. Might take a little creativity though.
how to put yamaha rhino rear differential bracket
Any mods out there yet for open and locked rear diff?
rhino diff

I know this is an older thread but just a thought for anybody still looking this idea may work for those of us who don't need to use the rhino to its full potential.

I use my rhino 450 for feeding our 12 horses at a horse park. I drive it around 3-4 miles a day half of which is on black top and its eating my rear tires. My question/idea is.
Can I remove one of the rear axles and run like that or will it put too much stress on the single axle still being used. If so
Could I put it in 4wd with the front diff unlocked to take the stress off of the single rear axle. Now would this put too much stress on the front diff with how many miles I put on this thing in a year. Again I rarely go over 20mph and im only hauling 2 bails of hay at a time around 120lbs to 180lbs plus me at 280lbs on relatively flat ground with muddy situations at times but not too bad.

Try it! It may pull hard to the side with the wheel that has power. I don't think it would damage anything but I do not know for sure, would have to try it to know!
It's a thought but not possible right? The hub mounts to the axle?? Don't think you can do this. Think you just to replace your tires when they wear or get a gator or something. It sucks becuase I wanted to drive mine on the street up north and its soo hard on parts becuase the diff. No idea why they couldn't have made the rear like the front. I'm sure it's some strength issue but can't aay
I think you could leave the outer CV stub so you could still attach the hub. It would not be under any load so it should do ok. Now that I think about it you would also need the inner CV to seal the diff. I am back to that idea of cutting the axle and making a sleeve. Since the axle would not carry a load there would not be an issue with it being weaker due to the cutting (or welding). You could keep spare axle, just in case you wanted to run locked again.
You are right I am sorry. Brain fart on that. I would worry about all that torque on one axle but see how it goes!
I was able to mount a open locking differential in the rear of my rhino. Built a makeshift drive shaft just to test it but have not finished the axles yet. You can see progress on my facebook page Sgroi Innovations.

(If I am not allowed to post that please remove it or tell me and I will remove it. I do not want to get in trouble on this great forum!)

Were you ever able to get the unlocked "differential" mod to work with the Rhino as you were discussing a few years back? I have a 2005 Rhino 660 with just 240 hours & 325 miles on it that I barely use simply because of the locked rear axles. I am considering cutting up an old rear axle, popping the spine into the "differential' and activating the front wheel drive when I need the added traction. Obviously I do not have radical traction needs so this might work for my use. Although, if I could install a proper differential for the rear end, even if some welding or mods were required, I would prefer that. Does anyone have an new experiences or ideas to share... other than telling me to buy a freaking golf cart :)
