Hi,
I have very strange problem with my Chally.
I did complete overhauling of my car, I put new polyurethane bushing in front suspension and all balljoints too, so the is no play in it. Then in workshop I set the correct front geometry (according to Dave suggestion), but......
When I driving forward front of the car is going up about 2 cm, so the geometry is changing - camber from negative is positive and toe is much "in" and is not possible to keep car driving straight.
After one meter on reverse gear geometry again is correct....

Do you have any idea what could be wrong?

You can get quite close with the popular static adjustments,
Really you do need to visit an alignment shop & get proper measurements so you can pin point any discrepancies.

But I visited an alignment shop and the set the geometry. And I did it twice.....

Can you remember if it was set to the factory specs, or for proper handling?
It's possible the front is twisted, they often aren't at all straight & need offset UCA bushes to help correct them.

Hi,
I measured once again the toe using the home made tool and I discovered that toe is too much in. It should be max 2.38mm but was set about 11mm. It is another proof that you can't trust in any mechanic skills....
I set about 2mm and problems DISAPEARED
Regards

Haha there ya go then, if ya want any job doin ........do it ya self!

I just did my Corvette a few weeks ago.

I checked the current alignment and it was all over the place. Obviously done by a "professional".

I do have a good engineer just around the corner from me that can do a very accurate 4-wheel alignment (at least you only have the front wheels to worry about on an old Challenger) but I decided to do it myself for a bit of excitement.

It took me a week!

But I went from the stock 0.25 degrees camber to 0.5 on the rear and 0.7 on the front Zero toe on the rear and just a fraction toe on the front with as much caster as the adjustments would allow on the front.

That extra caster made a very feelable difference in the steering. More feedback through the power steering and turns into the corners much better.

So even a car designed to handle like the C5 Corvette can be improved by more negative camber and positive caster.
