Memory Steer
Memory steer is the used term to describe a vehicle wanting to pull to the left or right after completing a turn in that same direction. There are many causes for this problem from an improperly installed front end part to a binding or worn front suspension/steering part. 
It's common for older vehicles with front struts to have memory steer because the bearings in the strut tower are worn or binding. It is also possible that the spring plate is worn causing this condition. Always use care when compressing strut springs while replacing these parts.
Binding front end parts will cause this problem. Check the tie rod ends, idler arm, and other linkage for binding. Be careful when installing these parts because some vehicles require the wheels to 
be straight on the final torque. If the wheel is turned the tie rod will act as a spring returning it to the turned position. Binding ball joints will also cause memory steer. Check all your pivot points in the front end. Worn front end parts can also cause this condition.
An unbalanced power steering rack can cause this condition. Pressure may be bleeding off from one side causing the vehicle to pull and display memory steer. Also look for a worn, over adjusted, or an under adjusted sector shaft in the gear box. It is unlikely a worn wheel bearing would cause memory steer. It may cause the vehicle to pull but the customer would be complaining of a growling sound first. The wheel bearing is the least likely of the four choices.
