Replacing rear springs

It's easier than you think. Just put the rear of the car up on jack stands under the frame rails then use your jack to support the diff. The hardest part is getting the bolt out of the front of the leaf spring.

Good luck
 
yea, I figgered that I might have to get out the sawzall or something if they were rusted too bad.

Now, I have another question.

The reason I am doing this is because my drivers side rear end sags and at the tire it is about 1-1/4 " lower than the passanger side. I have already lowered the front end with 1" lowering springs.

I like the stance better looking toward the drivers side.

I just checked the CJ Pony website (haven't called them yet) and they have standard rear leafs and a set by Global West. But I didn't see any that were lowering. So I am afraid that the rear is going to sit way too high with standard new springs.

Can anyone recommend a place to get lowered springs, and is it worth extra money to get springs with a brand name???
 
Yeah, the front bolt is the tough one. If it is stuck, go the WD40 route and be patient. Patience is the hard part.

The rear end has some alignment adjustment. That is, the rear can be swiveled a bit, the differential being the center of rotation. This is because of some play in the way the leaf spring locator and the spring perch/plate mate up. If it gets rotated, the car will track a bit sideways (rear end swung out a bit one way or the other).

To check, let the car down and point the front wheels dead straight ahead. Tie a string around the car at the center of the tires - just wrap it around tightly and tie it off. Look at the rear wheels. The string should touch the front and back surface of the tire's sidewall. If the string is off the front or rear of the tire surface, jack up the car, loosen up the spring u-bolts and adjust the rear until the string touches front and rear of tire.

Wow! This is pretty ironic. I'm in the middle of doing an "around $500" suspension build and was taking a look at my rear springs. Wouldn't you know that I have the same exact problem! My passenger side sits about 1-1/2" higher than my drivers side.

Let me know if you find a place with nice springs.

So far i've found a set of 'mid eye' springs from http://www.americanpony.com thats $150 and supposed to lower your rear 1-1/2". Which, over the years is probably where your/my car sits right now. I know there are posts floating around that talks about the differences between standard and mid eye leafs. If I find it, i'll let you know.

One more thing. I don't think (at least I didn't see) these particular springs are on their website. I actually found them in their catalog.
 
Get a good set of Mid-eye or Reverse-eye leaf springs from any of the major parts suppliers (MustangsPlus, MustangsUnlimited, NPD, etc)

Mid eye's will drop 1" from stock, and reverse eyes about 1.5"

I have Mid eyes, and now that I've lowered the front 2", I wish I would have done the reverse-eye leafs.

cool, thanks,

Ok, so I just went to Mustang Plus website. What is the advantage or difference between a 4, 4-1/2, 5, 5-1/2 springs??? :shrug:

Besides the obvious of more springs

update:

I just finished reading the performance differences between the different spring numbers. Looks like I'd use 4 or 4-1/2.

Generally speaking, the more leafs, the stiffer the spring. Stock originals were usually only 3 leaf. A 4 or 4 1/2 leaf should be enough for most street cars, although some prefer even stiffer suspenstion. More leafs also help fight axle wind-up and subsequent wheel hop, which can be a killer for differentials. The rear suspension should really be built with the front end and overall use of the car in mind. This keeps you from having as much buyers remorse and bruised kidneys/ego. ;)

Strange my rear passenger side is lower than my drivers side. I also just ordered all new stuff including Maier 4.5 leafs (160 'low' for 1.25 drop), KYB shocks, and heavy shackles from Mustang Depot for $490.
 
By far, the hardest part is the front bolt.

If you do have to go the sawzall route, get good blades and make sure you're cutting the bolt and not the hardened sleeve in the center of the bushing. Sometimes the bolt is rusted to the sleeve and you end up making 4 cuts to get them out.
 
it has begun

I would have liked to have posted that it is complete..............but.......one spring off is as far as I got over the weekend. Took 4 hours: getting out tools to cleaning up mess. I can't see the install of the new spring taking more than an hour start to finish. :rolleyes: I learned enough that the other side should go faster.

Made only one mistakes. :mad:

1. I placed the support jack under the pumpkin. This technique didn't work well with taking all the stress off the spring. I wound up using the sawzall on the rear shackle before coming to that conclusion. For the other side I'll have a jack support near each spring so that I can have better control.

Other than that, I got lucky with being able to remove every nut without without having to resort to the saw.
