Volvo XC70 S80 S60 V70 00 09 Complete Front Left Spindle Knuckle Hub 9461943 | eBay

Part Number 9461943

I snapped the bolt that holds the balljoint in. Broke the easy out as well. Price out an entire unit but not exactly sure what to call it. Steering knuckle? Spindle? Just need the part the balljoint presses into. I'd buy new but I see that they're almost $400. I'll get that one off eBay if I need to.

Thanks.

its the knuckle.

Thanks.
