My 72 Dart is still Squealing after alignment, It done fine before on mountain curves, put New leaf springs on, drove it & on some mountain curves it has light squealing, but on flat curves it don't, So I go to have a alignment & front raised up a little, seem like it went straight, rides a little smother, but drove it back up on the mountain & its still squealing around some curves,.. & I drove it just the same as I all way have before I put leaf springs on!.. The springs are in the holes, Could I over tighten the u bolts on one side & it do that?... He set the setting for everyday driving!.. Any suggestions?...

If you're sure it's in the leaf spring area, it would be a pain, but you could pull the bolts out and smear some more grease up in the eye holes.

Are you talking about tires squealing or suspension squeaking? If it is tires squealing then Does it handle any different when it makes this noise? Does the front or rear of the car push you out? If you changed the spring rate significantly it can and will affect the handling. It's a balancing act between the front and rear.
In theory, there is no difference between theory and practice. In practice, there is.

There is no rear alignment on that vehicle. If the rear is off the geometric centerline and thrust angle will be off. Alignment machine will show this. If it is off, the rear spring perch is broken, or loose. If the car has radial tires I set camber as close to zero degrees +/- 1/2 degree....try to get as much positive caster as possible. Usually hard to do if still has factory front suspension. FirmFeel.com has great parts. Toe-in 0 -1/32" in total. You can actually alter the rear alignment by using the shims mentioned in one of the above posts. Adding shims between the front spring hanger and the mounting boss on the car will effectively push the rear wheel on that same side towards the back of the car thus altering the relative position of both rear wheels to the front wheels slightly.

the build quality back in those days was horrible. the rear could be in there located anywhere, with up to 1/2" variation from factory blueprints without having broken, or worn out parts. very easy, but labor intensive, to relocate closer to specs by shims and slotting holes where needed. measure closely [twice or more] before cutting [hole slotting, shimming] once.

Rare, but I will quote myself; Does it have a Sure-Grip or even a spool? If so, tire squeal is very normal on hard & / or fast turns.

Well I been driving it & its steal doing it on 3 sharp curves, Its a short tire squeal or you could say a tire chirp, I took it back to wear I had alignment & he sead it seems fine & it just my tires, but if it my tires why did it not do it before, I know better then that, So I've been just driving it, its not as loud now, with music on you don't hear it. Something I am wondering about is can you over tighten leaf springs u bolts because they do look it to me??? By the looks of that spring pack, I would suspect you may have one or more broken leafs. Even if the leafs are not broken, the ends of each spring could be dragging on the longer leaf above it, that could give you a squeak as the suspension moves up and down. If you jack the car up, and look at the ends of each spring leaf, you may be able to see scraping or wear marks on the longer leaf. Gene
