1969 coil springs

<< < (4/4)

RoyceP:
I typically have to re - arch rear leaf springs due to metal fatigue. I have never had to do anything to coil springs despite 200,000 or even 400,000 miles. They just do not wear at the same rate.


Rubber parts I had to replace the front stuff several times in the course of 400,000 miles. Idler arms last maybe 25K miles. Strud rod bushings maybe 50K miles. Lower control arm inners last maybe 30K miles.

True, but they do compress from use, and the results from different manufacturing processes, where made and when can be a factor. They ain't identical or perfect, they just conform to a range "called a tolerance".
