Pro-Kits and sagging on Drivers side

[240sxTurbo]

Anyone else have this issue on their SVO. We have noticed since installing these units that one side(drivers) sits lower than the passengers side. For example, passenger rear is about 2.0in off the tire, drivers is about 1.0in. The car has 245/40/16 in rear, 225/50/16 in the front running of the 1994 to 1995 stock mustang wheels.

The issue is the rear scrubs, no suprise really, but only on that one side. I'm convinced that the other side shouldn't issue based on the ride we took but who knows until you really start to hammer on it.

Things we have done:
Swap rear springs from side to side, no effect, drives is always lower in front and rear.
Took both rear springs put in a press, used scale and put same amount of weight on them and measured, same height was the result.

The only thing we haven't done was call Eibach, but honestly it doesn't seem like the spring. The car has not been aligned yet so I don't know if that would affect it. Likewise not sure if its common practice to corner weight these cars but thats the only other thing I would think could cause it to sag, it just plain has more weight on that corner.

Car made its maiden voyage for the first time is 13 years yesterday, 2.1 miles, then we decided we need to fix the springs and the clutch pedal....

Any ideas is appreciated.

Thanks

check the insulators - make sure you put the ones in against the top of the k-member, and the ones on the spring that goes into the cradle at the bottom.

check the sway-bar, and bushings

past that, you can visualy inspect the control amrs, shock towers, and stuff to make sure they don't look bent, but it is hard to tell unless you are on a rack.

We have done most if not all that stuff, car is a very clean and straight SVO, at this point you could "eat" off the bottom of it every part has at some point been removed/redone or replaced.....

All new bushing everywhere too. Going to put in a call to Eibach too see what they say.

Thanks for the tips.

You might want to check the straightness of the sway-bars.

I had a friend that banged his head against a wall for a year trying to figure out why his car "leaned" to one side, swapped out everything and its mother.

Then he swapped out the front sway-bar and it fixed the prob. We layed them down next to eachother and the "bad" one was barely noticably tweeked, but it turnned out to be the culprit.

PS.....also, check to make sure the "pig-tails" of the rear springs are pointed in the same direction ( to the rear. )

[240sxTurbo]

Still an issue.........update

Well we have made multiple changes to see if the problem would correct itself on the car, below is a list of things we have actually done.

Verified spring position
Loosened up all the suspension, put load down on it tightened up
Loosened sway bars, individually, and seperately then re set everything.

My father being a engineer actually had his survey guys out on lunch one day to check the angle of the floor and verify that it wasn't sloping(not that we thought it was).

This is really crazy guys. The car has never been in a wreck or anything. The one thing that did seem to make a difference was we preloaded just the drivers side of the front sway, and put a 1/4in spacer under the drivers side front spring, and the drives side rear then appeared to come up. After 20 miles of driving however it appears to have settled back to the original position.

We truely are at a lose on this, its getting to be just irritating more than anything. We can put 225's on the rear and get ride of the scrub problem, but the car should sit level.

We are open to thoughts, seems that any changes made on the drives side rear(side that sages) also affects the other side by the same amount, ie put in spacers and the whole rear sits up.

We are almost to he point of getting it on a frame machine and making 100% sure its just not tweaked.

Thanks

what happens if you remove the end-links completly on the sway bar -- I know it will handle like crap, but does it sit level ??

If that don't cut it, I think your next plan may be to contact eiback, and say hey -- this thing won't sit level, is there a chance one of these is faulty, or even another spring has been swapped into the wrong box ??

The car did sit level with the stock springs -- right?

[240sxTurbo]

No go on the sway bar endlinks front alone, rear alone, or front and rear together.

The car did sit level when purchased, this has only been since the springs were added.


Funny thing is, we have swapped sides with the springs, even put them both in a press and put the same amount of weight on them and measured, they are the same spring rate it appears as the height doesn't change.

This car has been fully pulled apart and put back together, you could eat off the underside, so its very likely something isn't right somewhere but we have just about exhausted all the possible reasons why.

Eibach might be the only source for help, but I don't think another set of springs will do any good based on our testing.

Global west sells spacers for leveling Mustangs, so apparently it is not a new problem for the fox body.

Here is the link: http://www.globalwest.net/mustang%20...erch%20spacers

Have you recently added a set of subframe connectors. I recall a post where they were installed when the body was not properly level and caused a similar problem as you discribed.

[240sxTurbo]

Thanks for the link.....no subframe spacers were added to this car. Its stock rebuilt koni's on Eibachs....

That like will be helpful as we are to the point where we just want it level.

This is one thing you havent really mentioned. Are the springs "clocked" like Gator mentioned? The fronts particularly are sensitive to this as the spring cup is shaped to accept the end (or "pigtail" as Gator called it).

The "flat" sides of the coils go on the chassis side and the pigtail or open ends rest on the suspension arms. Might you have them backwards? Are there EIbach PN's on all the springs? (Might you have gotten 2 4 cyl units and 2 V8 units by accident?

Thats all I could come up with.

[240sxTurbo]

We have verifed that information as well since we have had them off and on 62,000,000 times......:p

The theory of the two of one kind and two of another kind is out the window as for that to be the case it would have to have been each side was different(ie right = v8 and left = i4).

Reason we know this isn't the case is we have swapped sides with them and the car doesn't change the way it sits.

Maybe we should just dump all the dead body's out of the drivers side and start over......

[GAboySVO]

This just a shot in the dark, but could one of those rebuilt Konis have been swapped out for a non-SVO type during the rebuild, ie: the spindle attachment bracket on the strut tube at a different height?

[SVOeric]

Not trying to point out the obvious here-- but
If you have swapped sides on springs, and the car still sits low on the same side, It would have to be a strut, or something that didn't change. -- that strut idea does sound logical, as I have a pair of new koni's with a klunk in one strut.

If you put my car up on a body lift, the drivers side wheel hangs lower than the passengerside( by like 4 inches). -- the only thing it can be is the strut. (or the car was seriously tweeked -- which it's not.

-- but the 4-week swap out is why I haven't replaced it yet.

[240sxTurbo]

I can honestly say that has never come to mind about the strut being the issue but at least it is something else to look into.

At this point we haven't got much to lose checking.

Thanks

Spring setting in LCA

After reading this thread and coming across the LCA's that I replaced recently, I observed that the springs on my stock
86 SVO did not seat at the end of the cup as others have mentioned. Just an observation after reading this thread of
how my SVO was put together at the factory.
