Before I take it into the shop, anyone got any advice?

At higher speeds, (above 40km/hr anyway) it is kind of normal, at slower speeds almost nothing happens when you turn the wheel 45' - 90'.

Driving along the elevated toll road, you need about 45' to counter the camber in the road, this just started a few weeks ago.

Is it likely a easy fix or mega bucks ? Job for the Isuzu dealer ?

yes I am clueless

Not knowing the exact suspensions setup, but it sounds like bush wear in control arms is possible with the arms moving back at load/speed putting slop in the steering

Or worn out track rod end joint or wear in the rack. If it started suddenly more likely to be a track rod end than the rack. That much play in a TRE is serious. It could let go.
