Kubota RTV X900 - Check your rear hub knuckle pins

Just been doing some routine maintenance on my Kubota X900 RTV and noticed something....
The rear hub knuckle pivot pins have sheared in the retaining plates.
I'm guessing that because there is no lubrication, that the aluminium hub is grabbing in on the pins and causing stress because the pins are fixed to the "A" arms.
I need to buy all new pivot pins and lubricate them well before fitting them.
