2005 Hyundai Elantra Engine short rapid vibration shake felt in seat and steering wheel equally while car in gear at a stop but not in Neutral or Park position, vibration/shake worse at higher speeds, ruled out tires, rims, ball joints, hub bearings brakes.
Everything done to vehicle so far:
Checked ball joints, tie rods, hub bearings for any play and found nothing wrong. Front and Rear alignment performed, Replace 2 warped rims with more than 1/8 run-out that were causing severe vibration at speeds above 50mph, Installed new tires, road force balance all 4 wheels/tires, re-surfaced both front brake rotors due to both slightly warped. This has taken care of 50% of vibration problem rapid shaking/vibration still there at all speeds, worst is felt at 55-70mph.
I feel the shaking/vibration in the seat and steering wheel, most noticeable in the seat. You feel it the best on smooth pavement. When I put the car into any gear while brake applied at a stop the engine shake/pulsates gets work as you start to accelerate forward this is the same feeling shake/vibration felt at higher speeds. When transmission is placed into neutral or park the shake significantly decreases and can hardly be felt. I believe the cause of the problem to be an engine/ transmission related problem like a motor mount or mount on left side where transmission is mounted or something on chassis/ frame is loose.
Please help, I have already paid $919 for replacement parts and repairs.
