ROUGH RIDE AFTER COIL SPRING INSTALL

[whitehummer]

they are only half cranked. is it possible that all the weight in rear is on the springs and new shocks would help?

Check the clearance on the front upper metal bump stops. If you are touching them with the upper a-arms, then you don't have any downward flex. Also, did you install extended shock brackets up front? And don't forget, coil spring suspension is a bit harsher than the air suspension and if you crank the front, you also stiffen the suspension a bit.

i agree with indy, could be a combo of the crank. and new springs in rear.

may just be you are not used to it.

I just dont get why people continue to screw around cranking on those keys... Just barely gives you enough clearance running 37's. If you ever have to really slam on the brakes, that nice big pinchweld (hiding behing the liner) on the firewall is going to love slicing into your front tires.

ive heard that a few times... but ive never heard of it happening

[[__--MUD--__]]

Who would actually admit that happened to them after being warned about it?

good question. this summer i do plan on doing the cognito kit... should make it easier on the front end

i took some pics to show you

in the third pic it looks like the upper control arm is sitting on the frame stop.
check and see if it is. That would deff cause your rough ride. I had the same thing happen when i cranked mine up. Replaced them with the cognitos and that fixed the rough ride and the alignment shop could get the alignment back in specs.

They are resting on frame. I started replacing the ball joints today and thought that might bring them up a bit but not enough I'm sure. So what exactly are you suggesting I do? Thanks
