2004 700 rear axle

I have a 2004 Polaris sportsman. The rear right axle broke near the differential. I purchased an aftermarket axle and after installation the axle slipped out of the rear diff. I re installed it 5 times and the same thing kept happening. I then purchased a Polaris used axle and it stayed in the first install. Now that axle broke by the diff. I ordered a new HD aftermarket axle and I have the same problem. The axle keeps slipping out of the diff. Do I need to order a new Polaris brand axle? Any suggestions?

Hi folks, I have been given an atv, a 99/2000 Polaris Xpedition 325 4x4. It's in pretty good shape and does run well when the carb is cleaned. I hope to learn some things about this machine here as I've never owned one before. I need to find a manual on it, service and repair ones. E-bay has a few as well as carb rebuild kits. It hasn't had any good maintenance at all done over the years. Anyway, I hope to enjoy it. BTW, at times I have a hard time staying connected to the site. I'm using Firefox and I don't have problems on any of my other sites. Just haven't found out what is keeping me from connecting at times.

2002 Sportsman 700 twin-sputters and dies in gear

Hello - first time poster here. I have a 2002 Sportsman 700 twin that has about 3k miles on it and I've had it for just over a year now. I bought it for plowing and a little bit of hunting usage mixed in - so I don't use it a lot. This summer I have been starting it every couple weeks and riding it a few miles to make sure everything is still working and battery is in good shape. Well now of course that the snow season is near, the thing has been giving me issues. It will start and idle just fine, but when I throw it into gear and start driving, it starts to sputter and dies. I can keep it running if I pin the throttle and keep feathering the throttle and give it a lot of gas. I'm thinking it might be a failing needle float valve in the carb. I'm going to get a carb kit and hope that fixes it. Do you think I am on the right track?
