[Healeys] FW: BN4 - 100/6 front suspension

[Bob Haskell]

Les,

By the installed height of the springs, I meant from upper spring perch 
to lower spring perch.  Are the springs compressed the same amount?

The front suspension a-arms - The a-arms go from the kingpin, spring 
perch to the frame.  The metastatic bushings at the frame can bind and 
the a-arms won't move through their full range of travel.  As you have 
the springs out, you can see how easy each side moves up and down. Do 
the lower arms move freely?  Do the upper a-arms (shocks) move without 
any binding?

Normally when assembling the front suspension folks don't tighten up the 
castellated nuts (and install the cotter pins) until the car is sitting 
on the ground with the engine in it.

Cheers,

Bob Haskell
