if it matches a bump it could easily be the front sway bar bushings - they tend to dry and you get a metal/dry plastic squeak. - easily fixed with some Silicon spray on the bushings.
however if it's only when you turn - I'd check all clearances in the front end
wheel lock to lock right and left and look for clearance
Do you know if it got one of the Balljoint recalls? - they recalled everything once and some of the early KJ's twice -
how to check
