pulling to the right
 

Just had a re built rack & pinion installed. then got front end alignment, went out on the road and noticed it pulled to the right ( did that before also but bigger problem at the time was steering and vibrations )
took the car back to Kaughman Tires they re did the entire alignment and results the same
the car has new tires from 1 year ago. The car now steers tight with the new rack & no vibrations but pulls to the right slightly
What to do >? Older gent at Kaufman's owns a C-5 he said possible break calipers

could be the way the tires wore with the "bad" alignment. To see if it's a hanging caliper, pull the wheels and compare the pad thickness on each side. If the pads on the right are noticeably more worn then I'd say it was a caliper issue.

Thanks

Post the alignment specs … Castor is probably all screwed up.

What would lead you to believe that after two alignments?

Having been a front end man back in the day, the first thing I checked after putting a car on the rack was the air pressure.
After having had two alignments with the same results, the next thing that I would do is switch the front tires from side to side. If I was the front end man, I would have switched the fronts after the first alignment. Brand new radials will sometimes (rarely) have misaligned belts and create a pull. If they are directional tires, I am not sure how that would pan out with the switch. Like I said, back in the day
A caliper can cause a pull, but I have also seen brake lines create a pull. With hydraulics, change both sides not just one, calipers or lines.
Tires can develop a wear pattern and the problem will persist.
Some rack and pinions have a centering valve adjustment.
Did your car pull before you had the new tires installed?
After the new tires were installed?
Or only after the rack was installed?

:iagree:

Tires, air pressure, calipers, wheel bearing, hydraulics or missed faulty/bent component are far more likely to be causing this problem than a wrong adjustment after two alignments.

The fact that the car pulls.

So by that informative answer, are we to assume that castor(sic) would be the only possibility for causing this condition? You say "probably" so enlighten us as to your rational for coming to this conclusion so definitively.

​​​​​​​We won't know definitively until the op posts the alignment specs, which is what I asked him to do in my earlier post. Once that occurs, a determination can be made. The very fact the op is asking about this condition after already having it aligned makes me think whomever did the alignment had his head up his ass. Do you think the alignment guy told him to ask the corvette forum why his car is pulling ?

Yes, there is a possibility that the alignment tech "had his head up his ass". However, if that were so, it is just as likely that he would have screwed up the toe or the camber. Rational thought though, after two alignments, would lead one to search out other causes for the pull as the poster in post #6 put forth. Stating that it is "probably" the caster is nothing more than a WAG if you don't elaborate on your methods(which is what I asked) of determining that diagnosis. As far as what the alignment guy may or may not have asked the OP is irrelevant to this discussion.

Castor is the setting that is most responsible for a car pulling. It is also the setting that is the least understood by the typical alignment tech.

As far a WAG goes, I would direct you to reread your own post # 7 where you literally list seven different things, all of which would have been at least visually inspected by even an incompetent alignment tech, if for no other reason than to upsell the customer.

OK, I can see this is going nowhere. You obviously have no faith in anyone's abilities but your own, judging by the condescending tone of your references to the alignment tech. It's not nuclear physics, what is there to understand about the steering axis being positively offset a few degrees?

Why would I have faith in someone's ability that allowed the car to leave while its still pulling ? That's stupid.

As far as understanding castor, I don't have a problem with it. I'm saying many other folks do. You might be one of those folks, or you wouldn't have made the statement in the bolded print quoted above.

Explain where my statement is wrong! Methinks the truth comes out that it is you who have no idea what they are talking about!

A castor split will be in tenths of a degree, not full degrees. You would know that if you had ever done an alignment.

The wheel alignment when left and right front have same camber and caster, the car will pull slightly to follow the road contour.
The alignment guy should know how to adjust the caster slightly more on the right side to help counteract the pull.

This means adjusting shim, is time consuming so most "lazy" alignment mechanics just do a simple Toe and go alignment.
Do not let them ask for more money, you pay for a 4 wheel alignment and expect the camber caster and toe in be checked and any errors be adjusted. A mechanic with experience will easily be able to estimate the shim change required, not needing a constant change check re change check.

I do my own alignments now, tired of lazy so called professional' s doing a toe and go or setting to what they think suits a c4..:smash:

My c4 drives straight with hands of the wheel, its not acceptable to have a so called professional do an alignment without recording all specs
and ensuring the car drives correctly during test drive. Making any changes needed, pressures of workload mean they don't really care if they return the vehicle and its not right without identifying what the cause is.

They have to check everything is sound before starting the alignment ....

You can add that changing castor, can change camber, and vice versa. So the shim game can be difficult for the inexperienced tech. Its actually kind of hard to get both castor and camber correct simultaneously, and do so in a reasonable amount of time, unless you have some practice.

Really!! Confirming my thoughts! 1/10th's of a degree. Really Hoss? LOL See link below for C4 specs.(the C4 is 5-7 degrees positive)
