ghaskett Posted April 19, 2014 Share Posted April 19, 2014 Recently replaced rear coil springs on '56 Special. After about 100 mile there is a significant up/down motion squeak coming from rear. I'm sure it's coming from both coils. Any up/down motion will set off the squeeks which started up around 100 miles into the installation. But before I tear into them again, I was wondering what you're thoughts are on this. Thanks! Link to comment Share on other sites More sharing options...
buick5563 Posted April 19, 2014 Share Posted April 19, 2014 There are supposed to be spring insulators that are possibly missing. Link to comment Share on other sites More sharing options...
JohnD1956 Posted April 20, 2014 Share Posted April 20, 2014 How are the bushings in the panhard bar? and on the lower shock mounts? Link to comment Share on other sites More sharing options...
Paul Falabella Posted April 21, 2014 Share Posted April 21, 2014 I second checking the transverse bar. My 55 was noisy back there, had the shocks rebuilt and rebushed the bar, no more noise. Link to comment Share on other sites More sharing options...
avgwarhawk Posted April 22, 2014 Share Posted April 22, 2014 There are supposed to be spring insulators that are possibly missing.I suspect this as well. Link to comment Share on other sites More sharing options...
bhambulldog Posted April 23, 2014 Share Posted April 23, 2014 The swing arms' attachment points may be suspect Link to comment Share on other sites More sharing options...

60FlatTop Posted April 26, 2014 Share Posted April 26, 2014 A standard shop and maybe a hobbyist will disconnect the rear shocks on a rear coil spring car, unbolt the springs, and pull down each side far enough to remove and replace the spring. Then hook it all back up.After 30, 40,50 or more years this method will probably twist the rubber bushings enough to shear them. It will bang going over curbs or in driveways and ride rough once the bushings are damaged.When I replace rear springs or do any service that extends the axle travel I loosen each bushing through bolt and make sure it slides freely on the inner sleeve.Then I insert a large chisel between the arm and the serrated end of the inner bushing sleeve and spread the components enough to release the grip of the serrations. That will give free movement to all the suspension arms and links. The axle can travel far beyond its normal positions without stressing the bushings.When the service is complete I rest the full weight of the car on the suspension and tighten to specs. A little anti-sieze on the through bolts and nuts will help in the future.Check the bushings for cracks or eccentric crushing. It they are shot only new will fix it.Bernie Link to comment Share on other sites More sharing options...
