Default Solution to simple issue escapes me

I'm sure this is something really simple but for some reason, it just escapes me right now.

Put as simply as I can, My 2.2 Solid Axle crawler will slightly 'lift' the front end when I turn the steering all the way to the Driver side. When I turn all the way to the Passenger side, instead the front suspension slightly 'lowers' itself. I must have something adjusted incorrectly?

if you have a frame mounted servo, lay it upside down, and check your end points while turning. when the steering on the axle maxes out, if the servo keeps pushing it can force the articulation, or burn out the servo.

Is the servo on the axle, or in the chassis? Better yet, what chassis is it? My friends Crawler King did the same. So we made a servo plate out of aluminium to mount the servo on the front axle and that stopped it.

With a chassis mounted servo the drag link can act like a lever when the wheels are in a bind. Hold the the tire with your hand and try to turn, you will see the servo tries to push the axle up or down a bit rather than turning the wheels.

The greater the drag link angle the worse the effect will be. Try to keep your drag link as close to parallel with your axle as you can.

Yes, all of you pretty much nailed it as my truck does have the servo mounted on the chassis. When it maxes out the steering, thats when it 'flexes'. So I should mount it on the axle instead, or can I just turn it?
