The shaft does not expand nearly as much as the existing OEM ones of these off my Nissan Altima. The OEM Nissan ones will go into the hole and expand to the point where there is not slop/looseness, These being sold will pull half way out of the same hole. I don't even trust these to hold things in place on the vehicle. I will end up going to a Nissan dealership at some point to get the OEM version for $1.50 apiece.
