Can old spring leaves be interchanged with new ones? I’m asking because I have a set of old springs that are still fine with the exception of one middle leaf from the driver’s side that has about 3" broken off an end. I’d rather swap leaves in favor of still using the old set as the new springs – sold specific for the '120 and sourced from “the usuals” – appear to be of careless manufacturer. Okay, I’ll be honest here: they look like third world crap. I will only use the new springs if I have to after doing some remedial work such as taking an angle grinder to clean up the leaf ends, removing paint and greasing between leaves, using bushings at each end that actually fit the original bolts and replacing the center pins to more match the dimensions of the originals. And I don’t want to do all of that knowing that I may still be fitting substandard springs.
Attached are pictures of old and new springs. The set on the left are the questionable new ones. The set in the center are early-day 8-leaf replacements for the 7-leaf originals on the right. Too bad the originals were prone to breakage early on as the manufacturer obviously took some pride in their product. Rounded edges and they taper in thickness on all ends. Nice.
Finally, I’ll add that three springs are pictured but I actually have a total of six – a match for each example pictured.So I wouldn’t be doing this to just one side of the car.
Any thoughts here from those who have done this before?
