Need help diagnosing this new noise
Posted 08 February 2004 - 10:37 PM
Its an 84 ea-81 with the 4spd 4wd.
The noise is tuff to describe but I'll do my best. It happens when your coming up to a stop the cars in neutral and your just barely rolling...if the stereo is turned off you can hear this noise it sounds like there is maybe some snow caught between the fender and the tire, a soft scrapping noise. Its related somehow to the wheel revolutions, the slower the car is moving the slower the noise is. I tried to figure out exactly where its coming from, it sounds like its coming from one of the wheels up front but I can't tell which side.
Things I have done so far
I drove around real slow in 1st gear to see if I could reproduce the sound and it doesn't do it.
Tried rolling backwards real slow and I didn't hear it either.
Looked under the car to see if the c.v. boots were torn or any other obvious problems.
It doesn't make the noise when its in gear or any other time except when your just barely rolling, I want to ignore it but I also don't want to get stranded somewhere. Its got me stumped and I don't really want to tear into it since I have no idea what is wrong. If you guys have any quick or cheap things for me to check that would be a great help. My only idea I have is maybe its wheel bearings?( I really hope not though) Thanks.

I say that cuz I've never seen brakes -- especially drum brakes -- that don't drag almost imperceptibly. And since you don't hear it except under the quietest conditions, it just might be. In gear or at higher speeds, the noise would be drowned out.
Anyway, jack it up and rotate the wheels by hand to listen, brakes or not. Hey, I'm not familiar with EA81 drivetrain so I can't offer anything more specific

Out side shot but what about a rock in your tread? or a skid or blemish in your tire? This could telegraph a noise through your sub.
Check your brakes!

I just went out for a drive and I couldn't get it to make the sound anymore? I check the cv boots their fine, both axles are pretty new, replaced both since I got back.

My guess is the one of the wheels is loose - either lug nuts, or the castle nut/spacer/bearing assembly.
I would jack up each corner, one side at a time and do the "shake test", by grabbing the outer edge of the wheel.
No shakes? I would still go thru and remove the wheel, cotter pin, castle nut etc., grease it up, and put it all back together at the proper torque.
I don't think it's the brakes unless something was warped. And then there would be performance issues too.
good luck, John
