A friend bought a Rancher 350 a couple weeks ago and I have it at my house. While checking the brakes Saturday once I got up around 8-10mph it started making a noise like screeching metal, thing rides fine and doesn’t seems as if the gears are stripped and the engine sounds great. Could it be diff. Or trans? Doesn’t make the sound going under 8mph. Thanks for any advise.

2003 Rancher ES 414.9hrs 2135 miles sound is coming from towards the back under neath and I didn’t make the noise until I had been riding it for about 30-45minutes. Personally I’m thinking it’s got something to do with the rear end diff. as when I removed the cap I couldn’t feel any grease. I have a 2016 Rancher but I’ve taken extremely good care of it and don’t have any issues but he bought this one used and we know nothing about the maintenance of the Quad.

There should be gear oil in the rear differential, it's not filled to the top so sometimes you can't feel it. I use a straw to dip it in there checking for water after a go through some deep mud to keep from draining it. Try removing the drain plug on the side and see if any oil comes out and take a whiff to see what it smells like.


Anytime I buy something used, I go through it before I ride it too far, check oils for contaminants, level, rear brake sticking, motor oil, stuff like that.
There's a link to the service manuals in my signature below, it's a free download and could come in handy.

IMO< I would suggest Draining the rear diff, and look at the color and amount of oil that is in there,
to re fill, fill till oil comes out the top of the fill hole!
drain into a clear container and look for water or metal in it, can place a magnet on the bottom to pool any metal to one area too!

could be a bearing on diff that is grinding and is DRY and as heat builds, it starts to seize up and makes your grinding noise!

I would also suggest that you ride atv till you hear noise gain, then jack atv up , all 4 tires off the ground and try and pin point the sound better then!
