Title pretty much sums it up. Took my '69 in for an alignment, the right wheel had -2.1 degrees of caster and that is the closest he could get. Left wheel had -0.6.
This is a good mechanic that I trust, and have known for years.
He mentioned the possiblility of a bent spindle... is that possible? Seems that might be possible on today's value-engineered cars, but back then the General used some pretty beefy stuff.
If it's worth anything, it used to be a 4-wheen drum car and I converted to front discs with a kit (including spindles) from Stainless Steel Brakes.
Thanks!

Bob,
What were the camber readings? Did he try to adjust the caster by moving the shims? With todays radial tires positive caster is better but negative caster is ok as long as both sides are within .5 degree of each other.
Neg caster is easier to steer at low speed (when parking for instance)with manual steering.
Pos caster tracks better at higher speeds ,if you drive on the highway alot you'll want this.

Camber was also out of spec. It was -1.1, and if he tried to correct that any more then the caster would get even worse.
The left side was +0.8 deg of caster according to the printout. Left side camber was +1.0 degrees (within spec).
Doesn't sound very balanced to me.

If I remember correctly, he took out all of the front shims and left some rear shims to get the camber close.
It rides okay except it pulls to the right. Is that what you were thinking? Or do you suspect another problem?
Thanks,

this has been descused in quite some detail. do some searches for "frame sag" thats what it sounds like you have. i have done a lot of work with this issue myself. measure your frame and you have several choices if it is, 1, get the frame pulled back out, 2, get off set upper arm shafts, or 3 get adjustable upper control arms like i have.

How long have you had the car? Sounds like at one time it was hit in the suspesion/ front frame area and the frame rail is rolled in. Have someone check the frame for true.
