Thanks everyone for your feedback!
Bad340fish, yep, I already spoke to Jim this morning and taking it to him as soon as I get the motor back in. He said he may put a B-body tie rods on it as well as checking out all the other components.

Yes good parts are a must. But it is not just the contributing factor. when coming down it is going threw a caster change and a toe change. the thing is to minimize toe change (bump steer).info in mopar chassis book. dougs car has very little bump steer. oops saw someone beat me to that.

wade get a copy of the old direct connection race manuals. this is called bump steer and it does cost et not much but some. the race manual show you how to map your front end out from all the way up to all the way down. you have to raise or lower the point of contact from the outer tire rod to the spindle. there are people that sell bump steer kits they work too. google bump steer I have used the manual on many cars, PIA to do, but it does help. Best fix is rack and pinion, but lots of geometry issues with that too.

The video of the challenger is from 2010 and I've done some work on it since then. Replacing all the bushes including the idler arm helped but didn't eliminate it. Limiting travel helps but may cause traction issues, especially with Caltracs.I also found out that E bodys use 2 different Pitman arms on manual steering boxes and they have to match the idler arm or the heights are different, this will mess up the bumpsteer as each side will then do it's own thing. At the same time, I flipped the tie rod ball joint/steering link bar to help with toe out on extension, but it still does it, though to a much lesser degree. I'm replacing the stock K member with a QA1 tubular after a big wheelie elongated cracked the LCA/torsion bar pivot mount, maybe this will help. IMHO, the only way to eliminate it entirely is going to a strut type front. HTH's

I have these on my car and it still does it. I think it happens when there is very little weight on the front tires. If you will go back and look at old Hemi Challenge races, before they tied them down so much, almost all of the SS/AH cars did it at the time. Here is a slow motion leave for my car and you can see them wobble. This is probably aggravated by the fact the most of us run so little toe in. My car has had the bump steer corrected. https://www.youtube.com/watch?v=TB47w1GF6TY&feature=youtu.be

A steering damper, like is used on VW's and Monte Carlo's. Used to see that problem a lot on old straight axle drag cars. Basically it's a sideways shock absorber.

When my Valiant was doing this I tightened the top control arm bolts super tight and it cured it.

My buddy's 68 Barracuda did the same exact thing. It would eventually loosen the bolts holding on the steering box. The fix is simple but sadly it's been a few years and I can't remember it all. Maybe it's bump steer? Maybe the fix was rod ends for the outer ball joints. Sorry I can't remember the exact process.

wade i have noticed that your front tires lean in more than mine do. Although they both seem to look fine when parked. That might be a function of different brand of front end parts?

looks like the upper bump stops are gone, or have been cut down

My upper bump stops are cut down to almost down to the numb for more travel.
