After completely rebuilding my front & rear suspension with all new components, I did my first home alignment. While it felt OK, it wasn't quite spot on and I took the car to a local shop where one of the guys who does alignments is older and is familiar with Corvettes.

After the first alignment the car had a bit of a pull to the right and the steering wheel was not centered. I went back and he made a couple changes and got the wheel centered, but the car still drifts to the right when I don't hold it about 10-15 degrees to the left.

I went back this AM and had it looked at again. He said the left rear toe was off a bit, and adjusted the front camber. The car is a little better, but to go straight down the road, i have to hold the wheel a bit to the left of center. If i let go, it gently drifts to the right.

I'm ready to try and solve this myself - looking for some input on how to get the car to stop drifting to the right. The alignment printout from todays session is attached. Any suggestions on how best to approach this?

Front looks really good. Although I can't see if the steering box is on high center.
rear is toed out. Needs to be toed in.
I'd start there. Get your rear wheels as close to zero camber as you can, get a touch of toe in , about a 1/8 inch per side.

When the steering wheel is straight it’s on high center for the box. If i hold the wheel perfectly straight the car will drift to the right. So as i drive i have to hold the wheel a bit to the left.

I’ll start with getting the rear camber zeroed out.

Most common cause of vehicle drift is tire problem and/or severe road crown. On lift specs look good but I prefer to set all my alignments with slight toe in as tire to road friction will want to push the wheels out. Even so, going by your spec sheet, with good tires and fairly flat road you should go straight. Since he’s already tweaked it a couple times I would first cross the front tires and see if it goes away or goes to the left now. If it does you know it’s in the tires. If the roads by you are crowned pretty good I would decrease the left side caster to compensate. Where I am in Indiana our roads have a pretty good amount of crown to them. I normally set left side caster about 1 to 1.5 degree less than the right side. Counteracts the vehicles tendency to want to ride down the crown to the right.

Not a guru…
modified specs were factory new setting (the tightest)
Make sure steering valve is adjusted right if you have power stearing.
after all suspension components and finally fixng axle end play…my 79 is very tight and straight.
tire pressure check as well.

I think the advice from 68blvert about caster is pretty good. Once I have everything set about right, that is how I make my final adjustments.
