steering and suspension Suspension Noise

[tdk930]

Hi,

 

I upgraded by 76 2002 to an Ireland coilover setup.    It handles great and the stance is nice.  The only issue its that it has that spring settling sound every time i take it out like it was just jacked up and lowered.  That DOING - DOING sound.  Any idea how to get rid of this?  Not sure if its front or rear.  I rebuilt the complete rear end and did bushings all way round.  Just want this noise to stop.

Sounds like a washer was missed between the upper spring perch and camberplate when everything was put together.  This would mean the hat is binding on the underside of the plate as you turn the steering wheel.  I've got the blow up diagram if you PM me.

I also had a "clunking" noise issue but it stemmed from the spring being very very  stiff (selected by PO) and "dropping" out when the suspension drooped with my coil overs.  The area I live in has lots of pot holes and discontinuities in the roadways.   Added a Eibach helper spring - see note:

 

From Eibach web site

A Helper spring is used to prevent the Main spring from becoming loose in the spring seat when the suspension is unloaded or at full droop. The Helper spring has very little spring rate, and therefore has no effect on the suspension characteristics of the vehicle. Up to 2" (50mm) of spring-to-perch gap can be covered with the use of a Helper spring.

 

 

By the way.....best to talk to Andrew or one of the guys at Ireland.......this is only a solution for my particular suspension problem.
