He's alluding to brake drag, I think. When you apply the brakes then the
drag is equalized and the pulling stops. When you release the brakes, the
right side drags and pulls the car that way.
Good call. The alignment shop should be able to confirm or deny this.
Pulling to the right hard. Tire pressure OK. Lugs all tight. Nothing
obviously loose underneath. Bushings look good. Any ideas what to check
before I head to the mechanic?
You need an alignment to see what the problem might be. Has there been a
curb or pothole in your recent past?

I would definitely jack it up and check for a dragging brake before
going to the alignment shop. If one is dragging go to a brake shop and
have it fixed. It needs to be fixed whether it is the whole cause of
the pull or not. If it still pulls, get it aligned.
Personally, I'd put the alignment ahead of a stuck brake because a stuck
brake would likely present with a different symptom set that included the
pull to one side, whereas the alignment would present soley as a pull
without the symptoms that would come from a stuck brake.
Having said that, one cannot discount the stuck brake. It could cause this.
It should have other symptoms too, and that's why I put it down the list for
the symptom given.

I have owned 2 different aerostars, and both at one point or other
presented with a strong pull to the right. BOTH times it was a caliper
problem. I never had alignment problems on either vehicle in 240,000
KM on one and well over 16000km on the other.
I'd do the simple (and free) check first.
Does it pull more after driving for a while, or from cold? Does the
pull change when braking? Better or worse with brakes on?
Nothing obviously loose underneath. Bushings look good. Any ideas what

I took it to 2 general mechanics I have used. First one is not set up
for alignment but put it up and looked it over. The only think he saw
was a possible leaking left ball joint. Took to another general
mechanic - also not set up for alignment. (I thought both of them
were...) He said nothing looked obviously wrong, brakes not binding,
recommended an alignment.
Went to the tire place I use, did an alignment and this is the before
Before alignment (all 3 should be the same photo)
When I drove out, the car pulled just as much to the right as when I
drove in. Turned around. Mechanic said the front right tire was were
worn on the outside and was causing it to be pulled. Also had lubed it
and said specifically that the ball joints and bushings were all fine.
I do need 2 new tires, but surprised that the pulling happened suddenly
due to a worn tire....
So my question is..... is the report in these photos show it is was way
out of alignment or just a little -- enough to cause the wear?
If it started suddenly I would suspect a damaged tire, either from
hitting a pothole or similar causing a belt failure in the tire. That
could cause a pull.
As for the numbers. The caster angles should match on that vehicle. When
they don't it can cause a pull. 1/2 a degree difference is enough to
cause issues and you have over that. With more on the right side.
Thanks Steve. Looking at the caster, before alignment it was 3.0 left
and 3.7 right. After alignment it was 2.9 left and 3.6 right. Does
that mean alignment needs to be done again?
The right front tow was -.15 before alignment and +0.03 after. That
makes sense to me because the front right tire was worn quite a bit on
The rear toe before align was -.13 left and -.07 right. After align was
-.24 left and +0.17 right. Is that also something to have corrected?
Sounds like your mechanic un-aligned it . Both sides ahould be very close
to each other , I'd be demanding they redo it and do it right or give me
back my money . I don't know about where you live , but here all 3 dealers
have the proper equipment , and none charges all that much - compared to
tires at $150 each .
Thanks Steve. Good specs - tighter than Ford or the tire dealer.
Here's what I got from the Ford dealer. Looks like tire dealer needs to
adjust the toe closer to mid-range
Toe Total - Min. -.2 Max. +.32
Toe: 0.06 plus/minus 0.26
Camber: +0.25 plus/minus 0.5
Caster: +4 plus/minus 2

It needs to be done, period. He didn't accomplish anything as far as
the caster is concerned.
. He made an iprovement on the front tow
You have a solid axle. There is no way to adjust rear toe, but the
truck is "dog-tracking". The aerostar has a 4 link coil suspension - a
bent component or worn bushing can allow the axle to shift back on one
side or forward on the other - causing the "dog track" If there is a
significant amount of actual toe in or toe out on a solid axle you
have a bent differential housing or axle tube.
I'd say find a real mechanic, and a real alignment man. The caster
should be between 2.5 and 4.5 degrees - and within 1/4 degree right to
left. The camber should be between +.8 and -.8 degrees, and within
1/4 degree between sides.
The clown that did your "alignment" is a hack.
If the tire is the cause of the pull it will pull the other way if you
switch tires right to left, and the pull will dissapear if you switch
front to back (the first thing to do when diagnosing a pull, by the
I had a problem similiar with a GMC Savana. Did alignments, replace
steering box, swap wheels, all on warranty, all to no success.
My daughter borrowed it for a couple of snowy days, lost control and
head on into a boulder.
The steering wheel was sideways, the hood in bungy cords, but it
drove fine and no more pulling to the left.
After the $9000 repair, is still running straight. Go figure.
