birds nest...?

[bluefoxamazone]

hello!!

while cruising my 53 cranbrook convertible, I hear noises from the rear end of the car, just like there is a birds nest with six fledglings under the car. I have checked but couldn't find anything loose...

Someone an idea..? could this squeeking come from the leaf springs perhaps??

Spring squeak is very likely. If it is, you should be able to duplicate it by just bouncing the rear bumper up and down,  and maybe have a helper listen closeby the springs.   Or get a heavy helper to bounce it while you listen.

 

Some early cars had the rear springs wrapped metal with holes in the bottom to add grease.  Are your springs wrapped?

If not the springs 2 other items to check are the u-joint and the lug nuts.

The springs on my 47 DeSoto squeaked,  They did not have the magic Mopar spring wrap, of great notoriety.  Attempts to grease them without taking things apart just didn't work. 

I found some PVC spring liners at one of the speed equipment houses, and installed the liners.  No squeak.  (In the photo, I'm getting ready to put in 2-inch lowering blocks.  Cool.)

Also check your exhaust hangers.

checked alle the above mentioned possible causes of the squeeking.. Greased all greasable points.

 Nothing helped. Yesterday made a trip and found the squeeking was most hearable at 40km/hr.

Of course I am driving a convertible and you hear and smell everything...

All suggestions welcome.

The hub could be moving slightly relative to the axle causing your squeak.  Check to see if the 'key' is missing from either rear axle (where the rear brake drum attaches).  Also check the rear drum attaching nut for proper tightness.

can you hear the squeak with the car stationary and bouncing the rear bumper with your body weight?  Simple test, but can tell us a lot.

Were the rubber boots on your u-joints intact? I know you said you've checked all 

greaseable parts but they may require a closer look. Check the fluid level in your rear?

Loose parts in your top mechanism? Lot of extra stuff to wiggle around in a rag top.

Spring shackles?

thanks for the hints guys. It seems like I have some more things to check...

I'll get back on this...

[bluefoxamazone]

nothing found so far.... ;-(

Loose or broken brake return spring inside the drum?

Had a set of front wheel bearings squeak like birds right before they seized to the spindle.  Thought is was a speedo cable till they let go.

found it... solved it..

I have pumped 1/2kilo of grease into the rubber sleeve around the universal joint and the noise is gone.

Thanks to all who have helped thinking about a possible cause.

best regards
