torsion bar suspension quirks

Posted by John Miller On 2010/2/16 23:21:06

Our 1955 Constellation drives like new except that every once in a while the rear will drop to the ground for no apparent reason. 60 to 70 percent of the time the suspension functions like it should.
When this happens the car will eventually adjust high then low one or two times then settle to normal and no problems for a day, week or month. The electrical system has been checked and the front end rebuilt and everything lubed several times.
Any Ideas on solving this problem would be appreciated.
