Just bought my kid his first Mustang...'90 5.0 Coupe (AOD to reduce the temptation to play), stock down to the air silencer. I know the suspension on this model is not the same as my GT, but the steering seems to have alot of slop. On a smooth, level road, no problem, no pull, no vibration. But if the road has ruts, this thing is allover the place. It's almost like the front tires are fighting each other. Where should I look first?
