Does it work when you force the source address to the desired address?
With ping, use -I address, with ssh use -b address.
3.7 contains some route caching that might play a role. Forcing a
source address might have the effect of clearing that cache.
Also, double check the routing table with route -n show, to rule out
wrong reverse lookups and remaining route entries for the old address.
