04 leveled Yukon hard to keep in the lane

[JD4440]

HI , I have a new to me Yukon that seems like you have to really drive it to stay in the lane/keep straight. It was bad when I bought it w/ 143k but just figured it was worn shocks or needed a line up. I've replaced the wheels and new michelins w/ road force balancing, new keys and extenders, 4600 series Bilsteins, and had it aligned . I'm at a loss unless I try poly sway bar bushings...........

Check out your idler and pitman arm, those take the grunt of steering play

It does feel like what I would think a loose pitman arm would feel like, but wouldn't they find that while being lined up ? It's almost like it has speed sensitive steering and it's not tightening up at speed.

They should find a loose pitman arm while aligning in fact they shouldn't align it if they notice that they should just tell you.
I'd take it back to them and have them drive it.

I get my alignments at the dealer and they just installed a new high dollar machine during the GM mandated remodel. Both them and the chevy dealer here did. And I know the man that does the work personally and he's very particular; He'd tell you if it was worn at all I'm sure. I guess it wouldn't hurt to have them look at it again, I despise paying for diagnostic time though.
