What's the condition of your idler arm?

[juit]

I'll check it in the morning and let U know

My shop used a high tech computer type and it couldn't be better.

Did they check all the front suspension components like ball joints, idler arm, tie rod ends, control arm bushings-- etc, etc. before they aligned it? If they didn't then you differently need to take it somewhere else.

[juit]

they told me that they all are in good cond, even when I did the shelby drop the check the arms and spring pearches

10-4--- Maybe they can do a 4-wheel alignment/check. They do it on newer cars---not for sure if they can do that on an older mustang.

Double-check the rear suspension and mounting points - I've seen rusted/broken torque boxes, bad spring eye bushings, cracked leaf spring (the 68 even had one when I got it), bent springs (especially by the ends) all can cause odd handling problems.

I would probably pull the rear springs, take them apart to clean them, then replace the pads and re-assemble with a new center bolt (pin) and new eye bushings and new upper mount bushings and then you'll know it's all straight as can get. All the bushings, pads and center pins shouldn't cost more than $40 or so. If you go for poly bushings it'll run a bit more but still a lot cheaper than new springs would be.

I've pulled stock springs out of cars where one side was a little bit lower than the other but wasn't too noticable until you sat the springs side-by-side (upside-down) and then there was almost 1" of height difference.

a mechanic told me that the rear suspension was toooo stiff compared to other cars, could this be the problem?

Old trick I used on 4 WD vehicles, drive slowly through a puddle of water and as straight as possible out the other side, check your tracks to see if you are dog tracking.. Pretty simple way to see if all four paws are going in the same direction at the same time..

Now that is just too logical. Well done sir.
