Feel heavy vibration when sitting at idle, start ups, and any time when not driving down road accelerating. Feel mostly when sitting still in drive when turning the steering wheel either direction but when you start driving you don't feel this vibration at all. We have replaced: harmonic balancer, plugs, variable valve timing solenoid and someone else replaced the motor mounts before it came to us. Can't seem to locate this problem and pouring too much $ into a warranty job!!

Hello! After hearing the problem became worse after changing the HB....The issue appears to be a broken Flex Plate...a flexplate consists of a piece of thick sheet metal that bolts to the crankshaft and torque converter...Guru...saailer
I would add that a flex plate is likened to the flywheel in a manual transmission vehicle...saailer

SOURCE: steering vibration while driving
check badly worn frt tire,bent wheel rim,loose wheel rim,frt tires may need te be rebalance
SOURCE: When my 2005 Infiniti G35x
One of the front wheels isn't balanced correctly and its vibrations cause a resonance in the suspension at that speeds.
You might also have a look at the shocks - if you have fitted new tires their hardness and misbalance might bring out the weaknesses in the shocks : these vibrations might be the first sign the shocks have aged and will soon have to be replaced.
You just need to have all the wheels balanced and the bushings of the suspension inspected at a tyre shop - a 30 minute/$50 simple job.
SOURCE: steering wheel vibration
Did they "turn" your rotors? They may have "improperly" turned your front rotors. This is common and they should correct this where you had the work done.
SOURCE: severe vibration and knocking sound!
My sons explorer had a similar problem. beleive it ior not, it was the shakles, they were severely wroughted, I changed them and the vibration is gone.
Take a look, it may help

There really isn't a groan noise but more of a vibration while sitting still with truck in or out of gear. After changeing the harmonic balancer the vibration got worse!
