Ok
any I dea why I'm getting a noise from my car that acts just like the alt noise from your stereo?? With my system out and no power to my amps this noise still exists. It goes up and down right along with the reving of my engine just like a poorley grounded stereo would do. It's been like this for the longest time but I've been too lazy to fix it. Any ideas????

hey Les remember how my car sounded with the manifold leak?? does it sound like that? where exactly is the noise coming from...

dat_nomad

Sup Dog,

Yeah i remember that sound your car had (supercherger ). Naw this is more like an electrical wine, but it's coming from the engine bay. If I had my stereo in I would swear it was alternator wine but the system is not on and has no power. I regounded the engine, the alt (which still has problems ) and the battery to chasis.
the engine and the battery now boast a nice stinger 0 guage wire to chasis, (all of which have been sanded down for good connection) and the alt has a nice 4 guage stinger wire. The noise has all the same charecteristics of the stero noise but no stero and not from speakers.

I'm surprised no one ever answered this post.
I guess it's a mystery.

Mine is a '90 SE (5-spd also) and I just noticed it doing the same thing. I personally suspect the tranny is making the noise. I found when I moved the shifter a little while driving I could alter the noise, or almost get it to go away. I just had my clutch done, and because of that I have new trans fluid, so I know fluid isn't the problem.
I know I didn't solve anything here - just relating my experience and a possible cause of the noise.

do you have rca connectors that are made of steel around the connector?then they are touching a part of the steel frame of the car underneath the dash or somewhere in the trunk....just tape them and voila!!!

dat_nomad

your forgetting even with the system totally out the car I get this noise. It definately IS NOT from the stereo. It is coming from the bay. I might have an electrical problem of some kind.

Mine makes the exact same noise, but only in first gear. And just as you described, I can make it go away by moving the shifter a little. Puzzling. Any diagnoses??

shvelle

If I had to guess? I think it's just normal wear and tear within the transmission. The gears aren't meshing as closely as they would have when new. Not sure there's anything you can do about it, barring buying a brand new trans? I suggest a louder stereo as the solution...

a few days ago someone had a similar problem and changing the alternator fixed it...hope this helps

rustangkilla

What does the alternator have to do with the transmission and shifter noise? Do you have a link to that post?

shvelle

The alternator has nothing to do with shifter noise, rustangkilla. I think drstillpatient was just responding to the original post - offering another suggestion as to the cause of dat_nomad's problem.

i dont think it has any connection...i was only informing you someone had similar prob...

anyhow...if you;re sure its shifter noise...(i assume you have a 5-speed) then it might be the shifter bracket...its a problem on the 5speeds...there is a rubber mount that holds the shifter in place...its right above the heat shield so overtime (like 12-13 years) the rubber stiffens and eventually breaks...

me and some other 5 speed owners had this problem sometime ago...IF and i say IF its the same problem then u'll need a new shifter bracket ($28 at courtesy nissan). the sympoms were that u could hear a whine/grind while driving and moving the shifter changed/reduced it.
the post for this one was titled "nissan's poor material choices" i think..thats all i remember.

AGAIN...thats all assuming its for sure that shifter noise AND if you have a 5 speed. just another attempt to help you...

p.s. thanks for the clarification shvelle

rustangkilla

Cool. I appriciate your help, I was just unclear on that last post You dont happen to have a part number on that bracket do you??

THanks!

drstillpatient

yeah the part number is 34560-51E05.

you can check the bracket by removing the plastic trim piece around the shifter and remove the dust boot beneath it. The bracket is like 4x3inch rectangular metal piece with a piece of rubber going across it. that rubber may be broken.
good luck!

dat_nomad

interesting suggestions guys I might give that a try cause i need a new bracket but this noise is still coming from the "front " of the vehicle. (reletive to my position in the drivers seat.

shvelle

Ahhh...., but keep in mind that where your shifter is, is not where your transmission is. The tranny is right about where you said the noise seems to be originating from (driver side under hood). If the shifter bracket were the cause here, then that could allow additional tension to be placed on the shifting mechanisim, which would then add friction to the gears - causing additional noise.
Bear in mind that I'm not saying this as fact - just as a possible connection between the two.
I'll definately be removing my console to check that bracket once the weather warms up - the noise is annoying!
