My VR 80-400 F4.5-f5.6 D ED AF fell about 6~9 inches onto hard pack snow. The zoom ring does nothing. The focus motor barely runs at all. I took it to an expert repairman (whom i trust) who said he can not get parts for it. Nikon repair is a fraud (I sent it in for a fall from back in 2012, they gouged me financially and the lens was never as smooth or fast again.) I have insurance but do not know if that will help. Advice &/or suggestions please.
