Re: 3K RPM engine vibration - 20R

Just checked this....haven't messed with it yet.

As for the drive shaft.....vibration occurs with truck not moving and when moving. Drive shaft is speed related, not rpms.

Can a pulley really make the whole engine vibrate? I've always diagnosed pulley bearing with stick/pole method. Put one end on the part by the pulley and the other on your head by your ear. You'll know if it's f-ed up.
