Default Car is pulling to the right.

Need some ideas as to why my car is pulling to the right. I just had the car aligned and its pulling to the right. It seems to brake straight, but I don't know if the caliper is hangin.

I was once told by a good friend in the auto industry that all new cars were designed with a slight pull to the right as a safety feature. In case you fell asleep on a two lane road you the car would naturally drive away from oncoming traffic. Recently I had an alignment done on my wifes car and it too pulls slightly to the right, but brakes straight. I just assumed it was the same reasoning and let it go.

Just got done chasing this demon away...and the caliper is most likely the culprit. If it were me, I would just replace the brake line and caliper, and be done with it.

Tires can also be the culprit. Try switching the fronts and see what happens.

If alignment is correct, just adjust the steering valve - you can make the car pull either way or track straight by simply turning the adjustment screw.

If you pull the driver's side tire off and look right at the power steering cylinder on the centerlink, there is an adjustable valve with a cover pointing out to the driver's side. Pull the cap off the the valve. Under the cap is a slotted head adjuster screw. This screw adjusts the "balance" of the power steering, and will apply more or less force to one side or the other. If you raise the front of the car off the ground with the engine running, you can adjust the valve to make the wheels turn fully one way or the other all by themselves... so you set the valve to its neutral center position in order to get the car to track straight. If the car pulls one way or the other, simply give the adjuster screw a "tweak" to offset the pull.

The adjustable valve is unique to the Vette steering systems - I thought this adjustment was pretty common knowledge since setting it up right is imperative to making a Vette track straight - misadjustment of this valve is the most common reason for a Vette pulling to one side or the other. It's only used on power steering-equipped cars.

Some roads have camber sloping to the right...if you let go of the steering wheel,it could wander to the right...
Can you elaborate more ??? Also,an under-inflated tire can cause that...

The stock alignment generally requires 1/8" toe-in....I run zero toe and vette tracks straight...

cap is off and there is a bolt instead of an adjuster screw?

It should be adjustable by turning. Raise the front end off the ground. With the engine running, turn the screw/bolt one way or the other - you should get to a point that the wheels actually start turning by themselves. If you count the number of turns from lock-to-lock on the adjuster, you can find the center position. This should be neutral steer. Make note of which way you turn it to make the steering pull which way. Once centered, leave the cap off and take the car out for a test drive - you can then easily reach in behind the wheel and make minor adjustments until the car tracks straight. Once done, put the cap back on.

I couldn't have said it better.. On my vette it was pulling to the left when on the gas. Drive your vette on a flat road. let go of the steering wheel and increase speed. If the steering pulls stop make the slight adjustment. If it pulls the same way you know you have to go in the other direction.
