I removed my FWH's from my hilux in order to clean them up and re seal them as one had worked its way loose. In the process I seem to have stretched one of the springs, the one that goes behind the clutch. Is it possible to get replacement parts new for these hubs? where from? Here's a pic of the difference. I do have an AVM spare I'll use in the meantime, but the Aisin ones are definitely a preferance.

Thanks
Nick
