Rattle with no solution?

[1of1]

Now I know rattles can be tough to find, but this one is very strange. When driving slow (in a long drive way )  there is a rattle sound coming from the tranny tunnel ( or the middle of the car to the rear....When you hit a bump at low speed I hear a clunking or a "can rattle sound ". I have put her on the rack and all the mounts are tight and exhaust seems to be in good order, no wear marks were something may be hitting, I know it's old, but you know when something is not right?, on smooth roads over 25 miles an hour you can't hear it.....  Any thoughts?

Thanks in advance

Is it an auto or manual trans?  Does the car have a console?  Could there be something under the console that's making the sound?    Cound a nut or drill bit have fallen into the frame durring floor pan replacement or something?

Long shot, but double check the top of the shock tower and make sure the bolts are tight.

4speed, console, No drill bits that I know of....This is a suspention sound......Like a wood ball in a bottle....... Cody, I will check the shock towers I rear never thought of that, any more Ideas would be great!

Cody, I check the towers front and back all tight.....The bolts in the rear you can move the shock a little bit when you twist it but not much, the rubbers are in very good shape......

I will give anything a shot!

Check and make sure the steering column shaft is centered in the tube.  Someone just this past week found that to be the cause of a rattle.  If it's not, you can adjust it with the tree bolts at the firewall.

Can you get it to make the noise by bouncing the front end while the car is at rest?

Do you have an aftermarket pinion snubber? I was hearing a rubbing sound for the longest time, then a few weeks ago I discovered it was my pinion snubber. I had it set for original ride height and never adjusted it when I lowered the rear an inch.

I was the one with the column issue and adjusted it as directed by the forum and it is now centerd and that noise is gone, Bouncing the suspention does not make a noise?

This sound is not a rubbing sound. I don't know what a pinion snubber is , but the car was restored complete stock, so I don't think so....But I am open to any solution

I did drive the car, and shut the engine down and the rattling is still there. Now the car was restored 10 years ago and sat since then, now when I push up and down on the car when it is parked there are no noises and the shocks seem to react as they are supposed too....they do stop and do not continue to let the car bounce, Now they are 10 years old and the rattleing seems to be produced when it hits a "sharp" bump. Could the shocks be bad from sitting for 10 years in shows and storage? Maybe when they have to react to a sharp bump they simply seize? Jaring the car......... I made sure the spare was tight along with the jack......Widows rolled up and down same noise???

I rebuilt the front end "all of it"...... A arms , ball joints on and on......

I think it's time for someone to ride along with you.  You can consentrate on the road and they can try to isolate the area the noise is coming from.  If someone you know has a stethoscope that would come in real handy.

Take everything out of the car that you can.  Spare, jack, anything in the glove box / console.  Have someone drive with you and find a road you can get the noise / rattle to happen on consistently.  Keep going over the road making the sound until you find out where it's coming from.  I've rode in the truck and upside down in the passenger seat to track down a rattle.

Check the drive shaft/u-joints for wear and bolts for tightness.
