if i use the front right to crawl up something it flexes as it should but if i try to the left it lifts the right tire up also. almost like if i put torque on that side the chassis leans to the left. i no this sounds funny but it is hard to explain. any help would be nice

run a search on torque twist should tell you what you need to know

Any chance you could post a vid clip?
Or even some body off shots top & bottom of your rig

All I can think of is if you made your own rear drive shaft it might be to long like:You glue a cut down male into the female shaft and then install a female on the other side..If one female touches the other under flex it could efect twist I ran into this on my old rig playing with driveshaft lengths....the other is make sure the 2front and the 2rear upper links are the same lenght as each other rear to rear front to front not front to rear cause that wouldn't effect anything to do with a articulation prob. like this..Or anything hitting an upper link...Chassis screw

But I don't know I'm just fishing in the dark here

my friend your crawler is infected with a bad case of torque twist

Yup, that's torque twist. The easiest and cheapest way to combat it is to try to put more weight onto the front right part of the axle and to put thicker shock oil in the left rear and front right shocks. Preloading the left rear and front right springs also helps, with more preload on the left rear. Ultimately you may need to use a 4-link suspension setup.
