Hello everyone.
My 2005 H2 has a vibration in the accelerator pedal and I only feel it when I lift off the pedal going 30mph+. It's only subtle but I'm hoping to find what it is before it gets worse.
Any ideas would be very helpful!

 

Moved this for you to the place where H2 questions go..... the H2 section.


Front tire out of balance? Uneven wear?

 

warped rotors?

 

I also have an 05 with the same issue. Ive had this issue since truck hit 50k miles. I am now at 89k miles. I just recently replaced the torque converter while fixing rear main seal but that did not help this vibration. I get it bet 30-40 mph. Its not the tires nor the rotors since I've changed both since I hit 50k miles.

 

I don't think it's anything to do with the front end or brakes as it only happens for a second when I let off the accelerator but with my foot still touching the pedal. I'm gonna check the drive shaft u joint this weekend as I've been told it could be this. I'm hoping it's not the front diff...

 

Keep us posted. I checked my front diff and mine is fine. I have same exact symptoms as you. I would love to know the culprit if you can figure it out.

 

If its just at 30mph as you let off the peddle, look mechanically at it from the pedal to the intake. Does it do that in park at idle when you throttle up to 30mph rpm and let off.

 

I have the same issue. doesnt do it in park. when you throttle up and speed hits 40mph (mostly), started to do it at 30mph recently, if you press the gas and allow truck to speed past 30-40mph you will not feel the vibration.

 

I would look at the pedal throttle control as well as the return spring on the pedal. To test the drive train load vibration return to the pedal, drive on a nice straight road with no one around and slip it into neutral around 35 mph and press the pedal and let off to see if it happens then.

 

It happens a little more noticeably at higher speeds. It doesn't do it in park either for me. I've tried it in N at high speed and it doesn't do it. It happens all the time over 30mph. As soon as i release the pedal, I feel the vibration with my foot. Never while accelerating, only when I let off. It only lasts about a second
