Steering and Suspension

Suplex reports that front coil-springs were subject to a major design change in March 2002.  Springs fitted prior to March 2002 have 4.25 coils whereas later springs have only 3.70 coils.  More critically, upper and lower pigtail dimensions changed at the same time necessitating revised upper and lower spring mounts.  Mechanics need to make sure they order the correct parts to avoid fitting problems. Colour codes on the OE spring help when choosing the correct aftermarket replacement part.
