whizzing noise in high gear

2008 RZR 800 with 1000 miles makes a whizzing noise when in high gear at around 4000 rpm took secondary clutch apart everything looked correct drained trans fluid looked correct no metal filings I've been told this is common with this model year also tried to change transfer case fluid but drain plug needs a special tool? looks difficult.....have a video but this site won't let me upload

Re: whizzing noise in high gear

Could be a vibration resonating something loose like a heat shield etc. Another alternative is that it could be belt whine. https://www.rzrforums.net/rzr-800-sp...t-whine-2.html

Re: whizzing noise in high gear

Had a similar problem. The transfer case was dry on mine and the prop shaft u-joints where dry and deteriorated. Changed the transfer fluid (no special tools required) and installed grease-able u-joints and the noise went away.

Hope this helps.

Re: whizzing noise in high gear

I checked the transfer case and mine was dry as well. It took the full 14 ounces. How is that possible? What happened to the fluid????
