I'm new to this web not sure where to find answeres to my problem. Just bought a 98 Tacoma 2wd 3.4 w/5spd. Turns out it has a shimmy/vibration that starts at 70 mph no matter if I'm in gear or neutral. I put in new KYB shocks and had front end aligned and wheels balanced but no help. Wheel bearings seem fine, they're not loose and the truck stops smoothly. Any ideas?
