I have a 2007 Priarie 360 4X4, it seems periodically that when I put it into drive the the belts start to whine. Is this an indication that they need to be replaced? It doesn't do it loud or even once I start moving only when in drive while at idle/in place. If they are in need of replacing....are they a nightmare to replace. I think I remember looking at the belt price and they were around 90.00 to 100.00 bucks. Any help would be appreciated, this is a newly bought Kawi for me, it didn't have much use from the prior owner and was bought new in 08. Thanks for the help!
