After a LOT of work on the suspension of my 74
Replacing the shocks (the original 1974 factory models) all the bushings and bringing most everything else up to modern standards my car is sitting higher on the front end than it was before.
I do know that the Rear leaf spring needs to be replaced, which I am currently searching the vendors for the best replacement part AND price. I am also replacing the stabilizer bar and bushings.
Do you think that the Leaf Spring replacenment will help to solve the front to rear balance issue? Are there any other possible problems I am over-looking?
Thanks for the help-

Did you replace the spring or put the old one back in?
If it's new springs, they should settle a little.
If it's the same spring, the shocks and bushings shouldn't make it sit any higher.
1.. Is the spring indexed properly in the upper pocket? The bottom end of the coil should be back from the hole at the end of the pocket
2.. Was the suspension loaded when you tightened the A-arm bushings? If they were hanging when tightened, they may be holding the suspension from going nicely where it should go

It is the old, (original 74 spring) which I think may need replacing, I do know that the stabilizer bar and bushings need to be replaced for sure. I guess the real question is that the height change happened after replacing the shocks..........?????????????????

You said you replaced all the bushings. Did you replace the upper and lower control arm bushings? If so, that's what Mooser's talking about. You have to tighten the bolts that hold the control arm bushing in place with the front end settled otherwise you get your nose in the air. If all you did was replace shocks either the shocks are wrong or the install is incorrect (which would be hard to do...). What shocks did you use? You said you brought everthing else up to modern standards, what's that mean?
The rear spring shouldn't have anything to do with how the front end sits. Can you post pics?

Yes to everything damoroso said above. Sounds like a classic error in putting the springs back in wrong. Did you do the work or did a shop? How much higher is it? Post some pics.

The top of the springs are not seated.
I had mine put in by a shop here in town.
I had them reinstalled by a better shop here in town.
1 1/2 hours labor.
Look familiar?

The springs have Cutouts where they fit in. I am probably sure they are done properly. It seems you would hear it if they were not seated properly.
The mechanic thinks the LEAF SPRING is worn out it lets the rear end squat down.
He is going to check it to make sure it is installed properly though.
We shall see

I'd still bet on the spring not being in the top pocket properly. The bottom one doesn't seem to matter as much as long since it should end before the drain hole, but the top does and is hard to see if it's in right.
You'd have to bring the rear down a lot to have the weight transfer off the front enough to raise it very high at the wheel well, tip of the nose maybe but not the pivoting point
What's the measurement from the ground to top of the fender arch?

Hi A,
I'm curious about what makes you think the stabilizer bar needs to be replaced; and also why your mechanic thinks the rear spring needs to be replaced.
Have you checked the rear ride-height dimension? That may give you some concrete info about the condition of the rear spring.
I know.... 'questions' not 'answers', but pehaps necessary questions so you can make a good choice.
Regards,
Alan

I am going to check all of these things tomorrow and give you the results.

Hi A,
Very near the front of the AIM is a sheet titled "Trim Heights". In 71 it's UPC 0, Sheet A-12.
There are dimensions to measure the body relative to the ground (tire size affects these), and also dimensions to measure the suspension (wheels, tires, etc., don't affect them).
Do you have a 74 AIM? If not perhaps someone can send you a scan of the sheet.
Good Luck!

YOU GUYS ARE RIGHT
The top of the springs were NOT seated properly. That is the problem with the height issue on the front end. We will have to fix that in the shop tomorrow. Should not be too big of an issue
I am hoping.

I have done a lot of suspension work last and this year with no problems. I guess the shop made a mistake on the front springs.
