Default Rearend issues

I have an 87 corvette and when I take it for a drive and I let off the gas and then give it a little gas you can feel the rearend pull the car to the right. It does the same thing when I make a right turn after I let off gas and then give it some gas but it does not do it when I make a left turn. Does anyone know what might be causing that. It is really aggrevating to drive that way.

Have the alignment checked mainly the rear thrust angle.

They did something wrong;
1. They either neglected to observe a failed suspension joint (tie rod end/bushing, etc) or
2. Did a poor alignment.

OK Thanks. Guess I will need to take it somewhere else.

Make sure the thrust angle is zero.
This is a must

You can ballpark this yourself. Get a couple of 4X4 blocks and a straight bar. Put the bar against the rear wheels on one side of the car and sight forward. Make a mark on the pavement where this line crosses the center of the front wheels. Do this with the other side of the car. Compare the difference between the two measurements. They should be the same.

A difference in tire circumference will create the pulling scenario. Check tire pressure then measure the circumference around the center of the thread using a 1/4” tape.
