Vibration when letting gas pedal loose?

[The Mexican]

Hey man ... I'm getting a freakin vibration when I let loose of the gas pedal, going downhill, at about 60mph. So far ...

1. Replaced all ujoints
2. Tightened Nuts, including the pinons

What can this be? Tie rods maybe?

P.S. I'm a freakin legal U.S. Citizen ... and so is my father/mother ... and my grandpops legally entered this country AND STILL fought against Mexico as an American during the Pancho Villa era. My blood is of Mexican descent but my heart is AMERICAN. So screw all of you who think otherwise!!!!

well i would have said check the ujoints but since you already did this i don't know what to tell you...

whats with the US citizen crap......?

Welcome to the site and i hope you get your problems, with your truck worked out.

Try experiment: on level road, accelel to 45 + m.p.h.
Windows open
ease up on gas pedel.
Did ya get vibes ?
did ya hear a noise that sounds like the vibrations ?

If yes, it's most likely you differential

( you can also lift a tire off the ground, rig in neutral (xfer case in neutral) and rotate, by hand, the D Shaft, listen & feel the axle housing...a worn out diff can be felt,,,it's not a strong feeling though...

Ditto on the chip on your shoulder..


Have you checked to see if your diffs need rebuild??
And.. are your hubs locked?

Springover?

You have a bad rear pinion bearing. This is common and expected. Time for a rebuild.
