I experienced this when reaching 80 - 90 MPH and I let off my gas pedal my car tends to vibrate but if I step on the gas it disappears. This only happens at around 80 - 90 MPH after I let off the gas and anything above that, it doesn't bother me. Any ideas as to why I'm experiencing this? Btw, I was driving interstate with a speed limit of 90.

 

if it doesn't bother you then how is it a problem?

 

Um. Where is there an interstate with a 90 mph speed limit?

 

i didn't want to say anything.

 

I had a problem kind of like that but it was when I went 60 the steering wheel would start vibrating, but it was due to unbalanced wheels.

 

I have a similar issue I've noticed... not sure what it is, I had my wheels balanced when I got the tires and everything was fine for a year then I noticed it starting happening after I took the front wheels off to check the brakes... I have since taken them off and reseated them multiple times, I guess I'll just need to get them rebalanced.

 

thats right where the rear end likes to howl... ( wait.. can i make a joke out of that?)

Seriously tho, i have solid rear diff bushings and while the vibration is now gone, thats where its the loudest, around 80 ish, freeway cruisng etc.

Vibration, well your rear bushing is prob shot... as is everyones really. And if not, its probably just another one. Check that first tho.

 

mine def. feels like the vibration is coming from the front end... how could a rear bushing cause this?

 

if its coming from the front then its most likely an out of balance wheel.. bad tire.. or alignment issue

 

Take off each wheel and check that the axl nut is tight. This is a common problem. And put loctight on all of them.

 

I don't think there are axle nuts on the front wheel hub assemblies.
