95 F150 with Vibration Problems
Hello to all and I hope that someone can help me with my problem.
I have a '95 F150 standard cab, 2WD, inline 6cyl engine, 4 speed tranny (3+OD) with some weird vibration problems and need help to diagnose:
Only happens in 3rd and OD gear.
Only happens when accellerating.
Sounds like I'm driving over 'rumble' strips.
I can feel the vibration through the steering wheel, dash board, arm rest, ect...
Is intermittent, sometime it happens sometimes not although it is happening more as time goes by.
Experiencing a 'loss of power' during this.
No codes, no check engine light, no check transmission light on gear shifter (I was told that if the tranny had problems, that the OD light will flash on the gear shifter).
When I release the accelerator and depress the accelerator again, the vibration and sound goes away 'most' of the time.
I do believe it is a drivetrain problem. Not the u-joints, diff, axels, or tires.
