Whining Noise

Re: Whining Noise

Try this: When driving above 35mph and you hear the noise, slightly swerve the car from left to right. Don't go crazy with the swerving, the idea is to lean the car to the left and right. Pay attention to the noise and see if it gets louder and quieter depending on which side the car is leaning on. If the noise gets louder when you turn to the left (car leaning to the right) and quieter when you turn to the right (car leaning to the left) then the problem is most likely on the right side of the car (the side that has the most weigth on it during the turn). From there you need to identify if it's from the front or rear. If it's in the front, then you're most likely looking at a wheel bearing/hub. If it's in the rear, then it could be an axle bearing or carrier side bearing.

As mentioned, it could also be a tire noise. Try rotating the tires from front to back, left to right, etc and see if the noise changes.

Re: Whining Noise

Ok, I went out and jacked the pass. rear up. I pushed and pulled on the top of the wheel and it moves, just a little, like a bad ball joint would in the front. At first I thought the lugs were loose, but it's the entire axle moving, clanking the rotor on the brake pad in the process. Any ideas?

Pinion nut maybe?

Pinion nut maybe?

sounds like it could be....you need to have your diffy checked either way with that happening...

Re: Whining Noise

not safe to drive?

[Firebirdkid96]

Re: Whining Noise

safe to drive but not for long distances. I'd get it looked at soon. Just get someone to pull the diff cover. Is it a torsen posi?

Re: Whining Noise

No, I wish. Just an open diff.

[Firebirdkid96]

Re: Whining Noise

then which axle is pulling, pass or driver?

[Bonemaro]

Re: Whining Noise

pass... actually, I didn't try the driver's side.

Re: Whining Noise

try to move the driveshaft in and out of the diff. it shouldnt move at all. that will tell you if the pinion nut is backing off. also try the driver's side. let us know/

Re: Whining Noise

sounds like pinion nut to me

Re: Whining Noise

Can the pinion nut back off if one is always droppin' the clutch and drivin' it like you stole it?

Re: Whining Noise

I had pinon nut back off on my truck before. when it started making the noise, I drove about 20 miles before it locked up.

Does your car make the sound in neutral around 35 or just in gear?

heck yes.

only thing that leads me to believe it may not be the pinion nut is that you have an open diff with play in the pass. wheel..


definetly just see if you can pull the Driveshaft in/out of the diff.

that will tell us whether its the pinion nut or not.

Hmm...scary. I been driving it 60 miles a day with it making noise for several weeks. Just crazy that way, I guess. Locked up you say?

If always makes the sound... neutral, in gear, coasting, braking, accelerating. Sometimes it will get a little louder under load.

I'll try to get under there tonight to check the DS.
