An alignment/tires/steering question. "Drives with pep"--habit of runs into curbs a lot. Just replaced front driver wheel and tire, and repaired one rear wheel. Now at high speeds, the steering wheel vibrates and shimmies like a bad dancer. Guys who did tire job may not have balanced them or put on a bad wheel. Go back, or find a different mechanic.
