Rear shackle angle difference?

wedge5 · Aug 10, 2014

For some reason my pass side rear shackle rotated backwards so the angle is different than the driver side. The car now sags on the right side. How do I adjust it back and how could this have happened? I have looked things over and haven't found anything obvious.

Pictures. I need to see what you mean rotated backwards

Sometimes this happens take the weight off the car and loosen up rhe shackle bolts and let it hang free then jack up the rear by the u bolts and with a prybar help the shackel go where its supposed to be.. tighten it up with the weight of the car on them. If it wont stay the main leaf is too short oor has too much arch in it and will need to be replaced with the right one measure from spring eye to spring eye both sides.... longer than stock shackle arms will do this also...... be careful you could knock your teeth out if the pry bar slips while tightening and the shackle swings around under load... I was a spring shop mechanic for a little while and it takes some strength to pull it around.... dont bite off more then you can chew with shackle arms.... high lift trucks were prone to the same thing weight in the trunk will help (200#) and tightening them on the groung

I kinda figured that would be hard to express in words. Basically the drivers side shackle is at a 90* angle and the pass side is at a 135* angle.

I am not sure if I can figure out how to post pics. I use an IPad these days and never learned how to post pics with it.

It sounds like the pass. side spring is sagging. Have you inspected it to see if it has any broken leafs in it?

Either that or someone parked a few hundred pounds in one side of your trunk and you don't know about it.

I gave it a visual but nothing stood out as out of the ordinary except the shackle at an 135* angle.

Jack up that side of the car until it's level, see if the shackle angle is back to normal. If you let the car down and the sag returns, I'd start looking into spring problems.

So its not a flipped shackle... Sometimes the leafs will break neer the u bolts and sometimes you won't see it till its off the car and you pull the center bolt.... if there old get a new set both sides and new u bolts because it could be that or the rubber bushings are gone.. or a combination....

A way to tell sometimes is to jack the car up and if you have to move the body up a lot more on that side than the other because the wheel stay on the ground is a sighn... like if I jack up a car with good springs once weight comes off the rear follows if you have a jack under the pumpkin and jack it up when you're just starting to see the body move off the stands... if you lower the jack and it drops 3' without the shocks hooked up there weak and done a foot not so bad its better to use a professional 4 point lift... just to check should be no charge...
