I hear a very light pulsating noise when i give it gas above 30mph..The noise would go away if i'm not on the gas or if i'm over 65mph...Dunno if it's still there but it might be that the motor is draining out the noise above 65mph...it sounds more or less like when you drive a car with lug nuts loose on your car..that clunking noise....I can't pinpoint exactly where it's coming from but if i had to guess, it would either be the tranny internally or my axles...what do you guys think? Btw...i can't feel it either...

New observation....I still hear it at 65mph...it's more of a knocking noise....very light noise tho..The noise go with the speed of the car....I dont think it's wheel bearing personally...

bad wheel bearing?

 

how about BAD cat? the comb inside is all f**K up? as it gain in some rpm the comb inside shakes ??? bad guess

 

i think the same thing was happening to me a few weeks ago. My teacher said it was my wheel bearing. I just kept driving on it and it went away though, so i dont know

 

Wheel bearing?...really...hum...what checks can i do..to see if it is my wheel bearing?

 

I think it might be your wheel bearings. I dont know how to check also check your lugnuts and make sure they are on tight enough. Its good idea to change your wheel beaings so your whees don't fall off. I had loose lugnuts and badwheel bearings

 

put your front on jackstands and run the car in gear

 

I don't think its your wheel bearings. If it was your wheel bearings it would be making noise constantly. And, it sounds more like a roaring noise.

Lift your car and check all of your suspension and drive train components. check for wheel wobble (tie rods, ball joints) To check your wheel bearings its pretty simple. Lift your car and run it in gear, with the wheel on. gently place 2 fingers on the coil spring. If you feel some harsh vibrations comming through the spring the wheel bearing is going bad. The wheel on the side you are checking must be spinning.

 

axles can do this aswell....if you have some spare axles I would just put them in and check out everythign at the same time that has to do with the suspension and wheels

 

your cv joints could be bad, or possible your wheel bearing.. id do what redzone says first,

if you have access to a lift, raise it up and hold the suspension parts and you can feel it if there is a bad wheel bearing, plus it will sound like a semi tire and get louder as your speed increased

 

it could be a main shaft bearing for the tranny.. my trans does that, irritating as fawk... ugly noise at low RPM's and goes faster the faster you drive... either that or release bearing in trans...

 

to check the transmission just push the clutch in while the car is in nuetral. if the noise goes away then it could be the throwout bearing or the mainshaft bearing......

the noise goes away without hitting the clutch....just need to let off the gas for the noise to go way.

Now what do you mean by a ugly noise....???

 

I have another question..if it's something that's internal in the tranny...what can cause a very slight knockin noise that i have?

 

I also had some type of noise and thought it was going to be the axles or wheel bearings until I saw a missing lug nut and checked. I found that some of my lug nugs were loose. I tightened them all up with a torque wrench all at the same torque specs. and the sound went away. I was already thinking how much it was going to be to fix.
