Handling issues.... any thoughts?

[PlumCrazyChris]

Guys,
I can't seem to get the front end on my challenger to handle right.   I rebuilt the front end with poly graphite back in '06, and really only have a few thousand miles on it.   Upper control arms are Moog problem solver offset.  I HAVE had to replace the sway bar bushings already, they were poly and split.   and I also just replaced the strut rods with adjustables last year.  It made a noticeable difference.

Could it be that I just need to replace all the bushings again?   I thought poly was supposed to last longer than rubber.... 

Symptoms:
when I drive over a groove in the pavement, the car swerves to follow the groove and I have to correct quickly. 
 
Any thoughts?

What size tires do you have on the front of the car? If they are wide, this could be a part of your issue. What are your other suspension parts specifically your steering box? In stock Mopar boxes/suspension there is a bit of slop and with an over pressurized steering box they tended to handle poorly especially on grooved roads. I don't think it is your bushings, I think you need to look at your idler arm, pitman arm and steering box.

To me it seems like you have a'70 Challenger alignment on your car. Designed for bias ply tires, it will track grooves in the road.
If you brought it to a shop and asked for them to align the front end, That's what you would get. A '70 alignment that doesn't take advantage of the moog offset bushings.
If I'm guessing right on the alignment, bring it to a shop and ask them to align it with as much  positive caster they can get...like 3-4*. Then -.5* camber and 1/16" toe in. It will make a lot of difference.

I would absolutely agree with these comments, many people either specific a "stock" alignment or the tech looks up old settings and applies them. A "modern" alignment as stated above with dramatically change the way the car handles.

I also agree with the alignment.
Had my alignment done to these similar specs and the car drives like a modern one.
