JD La165 - Whining when mower deck is engaged

[StoneyHill]

Our JD La165 started making a very loud whining noise when engaging mower deck. The belt has been changed, the spindles replaced thinking the bearings were bad as well as new blades put on in case they were bent. There isn't much to this deck don't know what else to check? Don't know if this is sheer coincidence but last time I used it before the noise began hooked up and blasted water under deck to clean out the grass - parked it till four days later to start this viscous cycle over again and midway through noise began? Any help would be appreciated!

You have several idler pulleys that could be going bad, take the belt off and spin everything by hand, if you find one a little noisy
by spinning by hand, it will be real loud on the running mower.

Thanks, checked the pulleys all was good, not a sound. So far verified the pulleys, changed the belt, and spindles, other ideas?
