Coil Spring Scoliosis?

Just finished wasting five hours today, installing and uninstalling, Currie 4" coils springs.

A fellow Jeeper who has installed coil springs on several vehicles, assisted. After installing the passenger front first we noticed the spring was bowing in and out and in and out all the way from the perch to the frame mount. Looked like a stack of dimes.

Anyway we commenced with the driver side hoping that having both in would alleviate the bowing on the passenger side...not so much.

FYI The axles is centered and all control arms are same length.

FYI these pics only capture one dimension, they are bowed both fore and aft.



]

We then noticed the Currie springs are not flat at the point were they sit in the frame mount. To demonstrate, I stood up both the Jeep's current aftermarket spring and the Currie spring on there frame mount side on our patio, (well tried in the case of the Currie spring). Here is a link to a short movie showing the demonstration. The movie takes a few moments to load.

As you can see the Currie spring is not flat on it's top. In addition, we found an OEM spring and laid it on it's top end and it also stood straight up.

Could this phenomenon explain why the Currie springs sit all akimbo when installed? These bow so much we could not connect the driver side swaybar link.

I am not a rocket scientist, for certain, but I feel as though I am not a simpleton either. What are we missing? Is there some technique I am not aware of when installing springs in a Jeep? I found no installation instructions with the springs.

HELP!

I assume the springs are new? That is pretty bad for new springs, mine did that after a year but that's because I didn't cut, rotate and re-weld the lower spring pads. When you lift the jeep the angle changes on the spring pad due to suspension geometry, normally it take a while for the springs to bow.

Ya and i have my caster set relatively low and the control arms are same length. Very frustrating. Calling retailer first thing Monday morning.

Did you have to compress the springs to get them in? The stand-up test isn't really a good one. I've seen some that will and some that wont.

I had the currie rock jock 4" lift installed a few weeks ago. The front springs bow forward slightly but not alot. I did notice theres a notch in the bottom spring pad to seat where the coil ends. I noticed a popping noise caused by the right spring rubbing the bump stop thats been to added the lower spring pad. A little lube and the popping is gone.

Yes we did compress them.

For clarification, are you saying you believe that the Currie spring's angled top (frame mount side) does not contribute to the bowing?

No, just rubber bumpstops.

Thanks gonna call them tomorrow. I am unclear as to how these springs can sit straight between perch and frame mount when they cannot sit up straight freely on their own. But I may learn something after speaking with them.

I won't say it's Currie's fault until I speak with them. I am relatively new to working on vehicles so it's possible I am missing something, but I can't put my finger on it.

I don't believe the top would cause that much of a problem. I've seen springs with hoaky curls at the top and have them end up straight. I've only seen that when the spring perchs have alignment issues (control arms to short or long), Or the springs were loaded inplace. After the compression did you allow the springs to relax before you put them in place and set weight on them? I know the fronts were a bear to get around the bump stops.

I think the springs were unloaded, calling Currie soon. Thanks.

UPDATE

UPDATE

I spoke with a Currie rep on Monday 12-21-09, after the aborted Currie spring install the weekend before. He conferred with a Currie mechanic who told him that some bow was natural. When I mentioned to the Currie rep that the springs could not stand freely on their top or bottom when laid on level ground, he said that observation does not indicate that a spring is faulty.

I said I would try the install again.

So the plan was:

Remove: 3" coils (not bowing) and 1 & 3/4" coils spacers

Install: 4" Currie coils and 3/4" coil spacers.

So yesterday, I worked with someone else on the removal/install. He also has many years offroading and install experience.

We set CA's to the lengths Currie recommended. We did not use spring compressors and the springs were unloaded when installed. The springs were seated on the axles perches and frame mounts properly. They appeared straight when installed and the axle was at full droop. Once the install was complete we bolted everything back up, threw on the wheels, removed the jack. Centered the axles. Here are the results of another three hours work.



Again, the springs bow outward on either side.

So I ask you, is the amount of bow you see in these pics, a "natural" amount of bow? Is it proper for Currie springs to look like this?

I hope someone from Currie will chime in...I will be contacting them AGAIN, tomorrow.

i have to say you have bad springs. the metal in the springs must be weak. i have installed many lifts and have never seen that. its as if the spring can not hold up the weght of the jeep.

just a thought you might want to pony up some coin for adjustable sway bar links. those rear links (you moved to the front) will limit your axle droop.
