Car actively trying to swap ends on track?

[RussMcB]

Here's a quick, free thing you can do. Are you familiar with checking toe alignment using strings? It is often done by using four jack stands to create a rectangle around the car. The two side strings should be parallel with the car's centerline. Then you can measure the distances between the string and the front and rear of the rims. By comparing the gaps you should be able to tell if a rear wheel is excessively toed in or out.

This method is very good at identifying a single rear wheel that is out of alignment.

An easier, quicker (and much less accurate) method I often do is to tie a string end to something on the rear of the car, like a tail pipe, then pull it around to the side of the car, touching the rear tire's rear sidewall and the rear tire's front sidewall, then seeing where it is relative to, say, the "ZR-1" badge on the front fender. If it is a foot away from the car, that rear tire has a ton of toe out. If the string hits the middle of the door, that rear tire has a lot of toe in.

Hope that makes sense. maybe I could make a drawing or find something on the web to better describe it. Maybe Google "sting alignment".
