I finally have my frontdriveshaft rattle fixed on my 2006 RTV 900 no thanks to Kubota.My kubota dealer changed out the fron driveshaft twice but the rallte always returned within 20-30 hours of use.I want to thank this fellow for his web-site he posted on here with pics and a fix for the rattle,here is the website www.cornejo.net/rtv900/ Thanks a million,the total cost was a wopping $6.06 for parts but labor by my dealer was $72.00 which I am not going to bitch about because the rattle is finally fixed with around 165 hours on the rtv.Other than th rattle I love this machine.coobie</p>
