THere has been some discussions on the Mustang II suspensions. Look in the archives section.

My guess would be that you are correct about the spring being defective. Is it new? Has it been on the truck a long time?

My truck's PO put on the FatMan MII IFS. I run a 351C and the front end weight of my truck is 2300# and I'm sure that's a whole lot more than any Mustang was. So, the springs were probably sized to the weight.

Hey, stuff happens.

 

I am definitely speaking up on a subject here wher I have no actual knowledge whatsover. With that disclaimer out of the way, is it possible that the Mustang II's had different springs for the 4 cylinder, 6 cylinder, and V8 options that were available on the car and is it possible that you have a spring set from a 4 or 6 cylinder? If you have the heavier spring from a V8, it is quite possible that it's just worn out. My daughter has a 97 Ranger and I have a 96 Explorer. I've had to replace rear leaf springs on both beause they were worn out already and the rear of the vehicle sagged (96 Explorer)/leaned (97 Ranger).

If you are concerned about pumping a bunch of time and some money into a project that you aren't certain will be successful, I completely understand. I felt that way with the Ranger and the Explorer but it did fix both of them. The springs were cheap (less than $100.00 at a local boneyard) and the job did not take all that long.

Again, not a suspension expert by any means, these are just my experiences. Good luck with it.

 

I guess we are assuming that your MII is a kit and not a cut and paste from donors.
Have your current springs ever been cut? Any amount of heat applied to them? Are you using Strut rods? If so original or after market?

And do you like patties or links?

 

Mustang II is From TCI

 

How long has it been in? Did you tell them what drivetrain you were using when ordering? Have you contacted TCI to see what they have to say? Mismatched springs would have shown up immediately. I'd take the springs out and set them side by side. If one is shorter than the other then you likely have a bad spring.

 

check to be sure that the spring on the low (sagging) side is not bent into an arc, it only takes a little bit to bow these springs if they have any bind in them at all. Also, make sure the spring is seated properly on the lower control arm. I had one of these problems once and it turned out that the spring was rotated about 10° Good luck!

 

Thanks Fellas....

 

in re my last post, the spring that was rotated was on the OTHER side and it made that side high, it was not the low side that was the problem

 

Let us all know what you find.

 

word of note, that mII's, thunderbirds, etc... had different spring weights for 4, 6, and 8 cylinders. What fatfenders56 said was my guess, that maybe the spring wasn't rotated in all the way.

 

Since the unit in question was a kit I'd expect it uses new made to order springs rather than OEM Mustang units so the chance of getting a mismatched set would be low and be obvious as soon as weight was put on them.

 

I suspect that he's got a bad spring, even if made to order. Problem will be getting a match without having to buy the pair. I would recommend getting down there and looking for soemthing obvious first, broken bolt, bracket, etc. If nothing is found, you can try replacing a shocks but in mky experience, it's almost always the spring.

Can you post a picture of both sides with the wheels removed and a picture of the truck that shows the offending stance??
