So I have a 2021 Polaris EV and one day had it pointed down hill and needed to backup in 4wd. So I engaged it and backed up, no problem. THEN I switched to forward without disengaging the 4wd and all sorts of noise started coming out of the front diff for 30 seconds as I decended a hill. So I turned off the 4wd and noise subsided. But now the front diff is noiser than it used to be. And after watching your video, I am thinking that with a polaris, each time you change from moving forward to backward, disengaging and then re-engaging the front diff should be done so the sprague control disc that is magnetically attracted to the friction surface, can rotate appropriately to be in forward or reverse engagement of sprague and rollers. I think this is a significant issue not mentioned in the manual anywhere about how the front diff works and why when changing direction it should be disengaged and re-engaged. I should change the oil and look for damage and am sad that I may have not used it correctly and caused myself some costs and now should do some repair work. I'd like to replace plastic parts in the diff and make it robust for a decade, plastic seems like a bad idea in a very high stress mechanical part.

Nice work!

Great video man! You did to forget at the end to mention to put diff fluid back into it, lol.

Ground issues is the awd cause for not engaging ??? I have a 2013 900 and and just stopped working

So if one left that spring for the neutral it would stay engaged in 4 wheel down hill on engine break?

Who sells the harness for the on and off switch ?? Thank you

on my rzr, i have to take my foot, off the gas to engage. same to disengage, if under load it will not come out of 4 wheel drive

Old Man Jeeping and Biking Yes. The HD Extreme Tru Loc Harness fixed my issue with the popping in front diff. I would not even run yours anymore till you can get it and install it. I broke my diff right after first rebuild without the harness. So save your diff till you get it

sproge? haha
