>>Why is this bushing
>>Why is this bushing so complex compared to the inner ones ( many parts make up one unit ), <<
Hi Bob, welcome aboard.
good question,
The outer bushings are 'true' bushings . Steel pins that swivel in a metal shell. This design is to provide smooth solid swivel motion without the deflection common to rubber, that tends towards impresise alignments and especially handling.
This design is right from the race cars and provides total stability where the 'rubber meets the road'.
You don't want to change this portion of the suspension, but careful inspection and replacement of worn/frozen pins and bushings may be neccesary to allow solid smooth movement.
