I'd try holding off on the WD-40.. Do you think you are apt enough to take it apart? Better asked, think you got it in ya to rip apart the steering housing?
I'm thinkin' it's prolly the end of the stalk, the little plastic piece, is broken.. Wear and tear? It has to be because it's not stuck.. The stalk, you can move it right? So, no WD-40 wouldn't do nothin'. If the entire STICK is stuck, then try LITTLE BIT. But, if you can jiggle then, yeah, it's the other end, its broken...
Whoa. that didn't help.. sorry bro.. wait out a little bit more, maybe you'll get a proper answer...
