Thanks for the suggestions...
I'm not sure how a bad tire/wheel would present 'bumps' only when holding the steering wheel to the left but not when going straight down the road.
I'm surprised that feeling the roughness when turning left would point to the left (drivers side) components. I would have thought that the PS CV joint or tire/wheel would be the one under more load and therefore transmit roughness. Assuming it's a CV joint, what is the progression of symptoms?
By the way, the 'bumps' are much slower than if they were generated at each rotation of the tire/wheel. 60mph = 88fps. Say wheel is 8' in circumference for calculation simplicity; that would mean 11 rotations(bumps) per second. 'Bump' is 2-3 per second. FWIW.
Had a chance to buy a used 'true-track' at a swap meet last week and passed it up. Should have grabbed it!
