Check the Driveline
ATV and UTV axles take a beating and wear if abused in the stock suspension setting, but when you add a lift to a machine the wear comes on harder and much faster. Be very leery of lifted machines that have not had the stock axles replaced with extreme angle units made for lifted machines. The stock axle travels with the suspension and is designed to only drop out at stock travel length. When you lift a machine the stock axle can no longer drop far enough during down travel and this results in premature wear. This also puts tremendous stress on the bearings of the CV joint. Inspect the boots on each axle both against the differential gear box and on the outside near the wheel. Busted CV boots invite trail terrorists and this is a potentially devastating problem. Any crunching or grinding in the driveline should be immediately noted as you head to your truck and leave.
