I believe this is a trick question. I'm not familiar with a single model of Caravan, Town & Country, or Voyager that had leaf springs. They were all designed with coil spring and strut suspensions.
If a Caravan had leaf springs it would be a bad idea to drive it with one broken, unless you want to scrape your undercarriage off on the road.
Yes
Coil springs in the front, leaf springs in the rear.
Broken are weak leaf springs on the rear.
You will have to determine why they are squeaking. Can be a worn rubber bushing or broken spring if they are leaf springs. Put it on a rack and do a complete inspection.
Could be the dowel in the spring is broken off or lose u-bolts.
Leaf springs can not be repaired, if they are broken or sagged, they should be replaced. You can buy complete sets from salvage yards or spring specialists.
coil springs and independent suspension replaced leaf springs to give a better and smoother ride
Leaf springs can be reset, or re arched. They will need to be taken off and taken to a specialty shop that has the machinery to reshape the springs properly.
Get new springs made.
Coil springs. Leaf springs. Torsion bar.
They must be crap! Our company has two dodge 1500's, and one 2500. We have had four broken leaf springs so far. we never carry heavy loads in two of these trucks. Dodge should recall them. Do i hear class action?
Coil springs are spiral. Leaf springs are flat blades of steel stacked on top of each other. Air springs are bags of air. Leaf springs are cheaper and carry more weight (hence often rear springs are leaf). Coil springs are wound tighter at the bottom so that their spring constant is greater (this is to make a linear force after compensating for gravity).
