This sounds like one axle pulling at a different speed than the other, as would happen if tires are inflated differently or different size tires.
If one axle is used a lot more than the other, you can have different wear in the gears.

Now those could be the original cause of the problem, which I expect is that the final drive in the front axle is slipping a cog in the gear.

If there is a bit of play that allows the cog to slip, it will likely require a bearing replacement, or more than one. Your first step is to determine whether you have metal filings in the bottom of the housing, a strong indication that a bearing is failing. If one bearing started to fail, metal filings by now will have contaminated the rest.
Your gear slipping a cog will almost never happen as long as the bearings are sound. But once it starts, you may need to take a good look at the gears to see if you have damage there too.
 
Have you ever changed the oil in the final drive case?
It should be part of your yearly maintenance.
Jack up the front of the quad and remove the fill cap.
Turn the wheels and inspect the gears.
Drain the oil into a clean drain pain - inspect it for metal shavings.
 
4x4 and go to switch it into 2x4? the whole front differential pops. SOmething is really wrong. Also, when driveing in 4x4 every 5 seconds or so it pops in the front. What could be wrong. WHat would i need to fix this. I am very handy, and any help is appreciated. Thanks
