Very noisy ride 1931 coupe
 

I was trying to figure out where all the noise was coming from as I drive down the street. I figured the car may be a little squeaky but this was ridiculous. Come to find out it, it was just dry leaf springs, I spayed them down with WD40 no more squeaks, just thought I'd pass it on - I love simple fixes.

Next noise is a large thump from the rear echoing through the rumble seat area as I go over big bumps. Seems the bottom pan of the trunk hits the top of rear end pumpkin. I put some rubber inner tube in there and it better. Can someone tell me what should the space be between the top of the pumpkin and the floor pan of the trunk? Is there a way to increase the clearance? Thanks

That is the purpose of accessory spring covers, to keep the springs lubricated and quiet. Each spring cover has a felt reservoir that you saturate with a high viscosity oil. Via capillary action, the oil gets between the spring leaves.

The improvement in ride smoothness is very noticeable.

Sounds like a nice improvement, I assume the springs need to come apart to install the add on, right?

They are just covers that wrap around the springs with an oiling felt on the inside. http://www.snydersantiqueauto.com/spring-covers

Looks like a great idea - anyone else use these with positive results? Found them at Mikes for $31.00 for the set.

Buy them, they work well.

I've installed a couple sets for customers, and I like them.
The sets sold by Bert's and Little Dearborn look like better quality than some others I've seen.

How long is your rear spring center bolt. I know of one model A that ended up with hole in the top of deff. case from a bolt that was not cut off.

On order from Macs hope to install soon

Installed a set this spring using used 600w from transmition. They dripped for a few weeks then stopped, no squeaks rides more smoothly.

Re: Very noisy ride 1931 coupe
 

I soaked them in 30 weight oil and mounted them. A bit of a mess and they dripped for about a week but man what a difference, it is so quiet now, thanks for the tip.

Anothe often missed lubrication point is the oil hole in the front hand crank bearing that is intended to lube the front spring in the crossmember

Well lubed springs along with properly working shocks make for a good ride ---but if the shocks don't work or are missing a dry stiff spring takes on some of the shock function---

Re: Very noisy ride 1931 coupe
 

Can you send a pic or explain where the lubrication point is for the front hand crank bearing you mention. I looked around not sure where it is - thanks

Page 359-360 of the service bulletins---all starting crank bearings now have a hole in the lower part of the bearing, flowing a little oil through this hole allows oil drain down between the sides of the crossmember and eliminates any possibility of a squeak occurring between the crossmember and the spring>

I too though --why does the crank need oil ----then I tried oiling there ---and saw a change in the lubrication of the spring ---the oil goes down the space between the centerbolt of the spring and the frame onto the spring

this is what Kurt is talking about... i didnt know about it either...thanks for bringing it up
if your bearing does not have a hole it shows where to drill one..
