Not sure if this is what they call 'Tramlining' but nearly every bump in road throws the steering and car off centre. This is quite scary on dual carriageway doing 60. Even driving cautiously still feels dangerous.
Have checked my front shocks and dont appear to show any signs of leaking also ARB links look a bit tired but I have seen worse.
I do seem to remember having something very similar on my old MX5 but front shocks were gone and replaced and sorted the issue out.
