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.
