I've got an OT car with sagging rear leaf springs. It's a back-up daily
driver. Anyhow, I really want to fix the sagging rear (it's been irriating
me for years now). Is it better to get long add-a-leaf's or to have the rear
springs re-arched?
Thanks,
Carl
My choice would be to have the springs re-arched.... adding an extra leaf to
the pack seems to help as well though the ride will get a little rougher.

Thanks, Jim. Any thoughs on how much the service will cost and how long it
will take? Will the ride change consierably?

Personally, the cars that I have treated to an extra leaf always seem to
drive nicer. The feel is a little crisper.... something I like.
Been a long time since I've been around a spring shop... I worked in one in
the 70s and we re-arched a lot of car springs. I would think 2 to 3 hours to
re&re the packs, a couple of hours between the rebuild and hammermill, and
maybe a $100 or so in leaves and hardware - maybe a bit more if the bushings
in the eyes are gone (remember, I'm thinking in Loonies and not
Washingtons).
Best bet is to phone spring shops in your area for a quote...

The spring sags because the metal gets weak and
loses it's "spring". If you re-arch them, you have not
gained that ability back. And unless it's done right,
you'll lose even more.
Check in to the price of new springs. Sometimes,
there's very little difference in cost between new and
re-arched.
Also, consider simple spring blocks or a longer
shackle.

Actually, there's not much lost in the way of "spring".... the springs sag
through the same dynamics that the hammermill can unsag them. The continuous
loading of the spring will cause the metal to "re-adjust" itself over time.
Longer shackles usually introduce a modicum of instability since they tend
to "rack" more than the shorter stock shackles. Most of the installations I
have seen tend to bend the back 1/3 of the spring down rather than bring
ride height back.

Why not just replace the springs? Leaf springs are not the expensive. I
bought a brand new set for my Explorer for $75 each.
