My son told me that a few times doing 60 mpg on the highway that his car will suddenly pull to the left. He does not hit a bump or put on the brakes at this time to cause the car to pull. I have not had a chance to take a test drive yet. Any thoughts?

Ball joints have no grease zerks ... so ball joint could be bad,  Also, tie rod, and even the lower control arm (rubber bushings) can break down over time.  Also, bad Hub can cause this,  

 

How many miles on the car?

Have the tire checked for a broken cord.  Had a similar problem last summer. 

sticking brakes, some kind of failure with cv joint on left axle????

 

start with a careful inspection of driveline, brakes and steering components

I'll check all those items and report back. 117k for mileage
