Hi, I have a 2004 Polaris sportsman 700 and I noticed that the four-wheel-drive was intermittent. I raise the machine off the ground and gently gave it a little bit Of gas in 4×4. Once in a while the front wheels would spin slightly and then stop. I Took apart the 4 x 4 switch and make sure the contacts were clean which they were and that made no difference. Also want to mention that my digital display is gone a lot of the time and comes back once in a while. Not sure if anyone has good advice for me. It seems it really doesn’t Go in 4 wheel drive anymore. I noticed the shaft coming from the transmission goes into the front differential which then connects to both left and right drive shafts. I don’t know if the four-wheel-drive Connects inside the differential or at the front wheel themselves. I do see two wires coming down that go inside the front differential. Thank you
